In 1994, SIG Sauer and Federal Premium co-developed the .357 SIG cartridge to replicate the ballistics of the 125-grain .357 Magnum revolver load — when fired in a 4-inch barrel — in a high-capacity, semi-automatic pistol.
Pistols firing the .357 SIG can exceed the capacities of typical K- and N-frame revolvers by 2–10 rounds, providing both law enforcement and private citizens with increased firepower. At the same time, the .357 SIG is a highly energetic cartridge, and many of its proponents tout its greater stopping power compared with its closest competitors.
So, I decided to take a closer look at the Best .357 SIG Handguns currently on the market, to find the most reliable, durable, and accurate pistols you can buy in this caliber to make an informed decision on which is the perfect option for you and your shooting style.
.357 Magnum power in an automatic… Why the .357 SIG?
The .357 SIG is derived from the 10mm Auto, and while it never became as popular as the .40 S&W, it has seen adoption by the highway police of several states, the U.S. Secret Service, and the Federal Air Marshal Service. Some gun enthusiasts also regard the cartridge as the superior choice for self-defense due to its high muzzle energy and increased barrier penetration relative to more common handgun calibers.
In Lucky Gunner’s testing, .357 SIG self-defense loads consistently meet the minimum standard for penetration established by the FBI. In addition, many .357 SIG JHP bullets expand to approximately six-tenths of one inch or more. Finally, some advocates of this caliber emphasize the importance of “hydrostatic shock” in inflicting wound trauma.
Best .357 SIG Handguns
Let’s start with an Austrian favorite…
1 Glock 31 — Best .357 SIG Handgun for Home Defense
No list of “Best Handguns” would be complete without the Glock. In 1986, the 9mm Glock 17 reached American shores, and it didn’t take long for the Austrian manufacturer to establish itself as a household name in the U.S. Among police departments, competition shooters, and private citizens interested in concealed carry, the Glock is the default centerfire handgun.
The Glock 31, or G31, is the .357 SIG variant of the full-size 9mm Glock 17, introduced in 1996.
The Glock is a locked-breech, semi-automatic, striker-fired handgun with a polymer frame. The pistol has a no-frills exterior and few external controls to manipulate, contributing to its simplicity. More importantly, the Glock is reliable in the extreme — an essential criterion for a self-defense handgun.
As the Glock 31 is a full-size weapon, I’m listing it here as a home-defense handgun. It’s not as concealable as some of the other firearms, but for protecting your home or vehicle, there are fewer practical limitations regarding weight and bulk. For these reasons, selecting a weapon that’s easier to control and that recoils less is prudent.
- Barrel length: 4.49 inches
- Overall length: 7.95 inches
- Height: 5.47 inches
- Width: 1.26 inches
- Weight: 33.16 ounces
- Magazine: 15-round detachable box
Glock firearms use the company’s signature Safe Action System, which comprises three passive safety devices:
The trigger safety consists of a spring-loaded lever located in the center of the trigger face. The trigger safety blocks rearward movement of the trigger until it’s fully depressed, becoming flush with the trigger itself.
A multitude of firearms uses a similar kind of system, such as the Springfield Armory XD.
Firing-Pin and Drop Safeties
In some firearms, the firing mechanism is susceptible to impact. To prevent unintentional discharge, manufacturers often incorporate a system that prevents the firing pin or striker from moving forward until the shooter deliberately presses the trigger.
In the Glock series of firearms, pressing the trigger causes the trigger bar to raise the firing pin safety, allowing the firing pin to move forward, entering a ready position. In addition to raising the firing-pin safety, the trigger bar also engages the firing pin at the rear, ensuring the pistol is drop-safe under a variety of circumstances.
While the Glock’s passive safeties have become increasingly common on modern combat handguns, those who prefer manual safety catches will find the SAS lacking.
The Glock 31, as a polymer-framed handgun, is relatively lightweight — 33.16 ounces (w/ loaded magazine) — compared with many comparably sized aluminum- and steel-framed weapons. Due to the high velocity, lightweight bullet, and low bore axis, the recoil impulse tends to exert force rearward more than upward.
The pistol is also somewhat front-heavy, which helps keep muzzle flip to a minimum. You’ll feel the recoil against your palm and wrist, but it’s manageable and consistent with proper technique.
The G31 is, by far, the easiest to shoot among Glock pistols in this caliber.
Glock pistols are not known for their crisp, competition-grade triggers by default. A common complaint regarding the Glock trigger is that it’s “spongey” — the break is not a positive, metallic snap. For some, the creep is also excessive.
That being said, the trigger action is sufficiently light and predictable for an experienced shooter to master, as evidenced by the proliferation of Glock pistols in formal matches. Many competition shooters alter the trigger action in some way, but the stock trigger is adequate for most practical purposes.
Where the Glock differs from DA/SA handguns is that the trigger breaks at the same weight every time — approximately 5.5 lb — and the stroke and reset are identical from one shot to the next.
Sights and Accuracy
Standard Glock sights consist of a front blade and a rear notch with a U-shaped outline. As the OEM sights are plastic, some gun owners choose to replace the stock sights with aftermarket metallic sights. Whether you prefer more traditional three-dot combat sights, tritium night sights, or something else, the iron sights are easy to replace, and there are myriad options available.
Reliability and Durability
The Glock series is known for its functional reliability, as discussed in the introductory paragraph, but it’s also durable, featuring a nitrocarburizing process called Tenifer. This increases wear and corrosion resistance while also creating a non-reflective matte-black finish.
The standard magazine capacity for the G31 is 15 rounds — the same as that of the 9mm G19 — but both 10- and 16-round magazines are also available.
The Glock Gen4 series incorporates removable backstraps, which allows the shooter to adjust the grip frame dimensions according to the size of their firing hand.
The grip frame is textured, and in Gen4, Glock substituted a pebble-like stippling pattern for the checkering of Gen3 pistols while retaining the three finger grooves molded into the front strap.
If you’re interested in customization and accessories, Glock handguns have a definite advantage compared with their competitors. From spare magazines and replacement sights to custom grip texturing and extended controls, you can find practically anything to further personalize your Glock firearm.
Let’s move on with a more compact option. the…
2 Glock 32 — Best General-Purpose .357 SIG Handgun
As a general workhorse and for concealed carry, a full-size pistol may not be ideal. For a more compact alternative to the Glock 31, consider the G32 — the .357-caliber variant of the popular 9mm Glock 19. For concealed carry, the G32 strikes a balance between the full-size G31 and subcompact G33, offering less bulk than the former but more control than the latter.
The critical dimensions for concealment are the height — i.e., from the magazine floor or base plate to the top of the slide — and the length from the muzzle to the rear of the grip frame. To illustrate how these factors can affect concealment and holster selection, Massad Ayoob demonstrated the differences in height and length between the Glock 17, 19, and 26 pistols in a presentation for PanteaoProductions.
The height of the G32 is 0.43 inches less than that of the G31, while its length is 0.67 inches shorter. This allows the G32 to be more easily concealed under clothing. Unlike the G33, the G32 has more available surface area for achieving a full-firing grip — your little finger will not curl under the magazine — allowing for a more “shootable” weapon.
- Barrel length: 4.02 inches
- Overall length: 7.28 inches
- Height: 5.04 inches
- Width: 1.26 inches
- Weight: 30.34 ounces
- Magazine: 13-round detachable box
Safety and Trigger Press
As with all other Glock firearms, the G32 has the same Safe Action System described above — there is no practical difference. The trigger action of the G32 is practically identical to that of the G31 — it’s a standard Glock press. Like the G31, you can modify the trigger by installing a competition-grade kit if you find the stock Glock trigger to be inadequate for your needs or preferences.
The G32 is lighter, by roughly three ounces, than its full-size counterpart, and the recoil impulse is expectedly greater; however, there is sufficient gripping surface available to maintain control of the weapon. The weight seems to exert less of an influence on the recoil than the length. As the G31 is more front-heavy, the muzzle flip is lessened. It is sufficiently controllable and “shootable” to fulfill the role of best general purpose .357 SIG handgun.
Sights and Accuracy
The Glock 31 is the most accurate of the .357-caliber Glock handguns, but the G32 is a close second, achieving group sizes of approximately 2.0 inches at 25 yards.
As for the sights, they’re standard for the Glock series but easily replaceable, and you should consider replacing the OEM sights if you intend to participate in competitive matches or attend classes at a reputable shooting school.
A more compact weapon, the Glock 32 sacrifices two rounds of ammunition for a reduced height, decreasing the magazine capacity from 15 rounds to 13.
Like the Gen4 G31, the G32 has removable backstraps, so you can customize the fit of the pistol. The pistol’s size lends itself to a high degree of control.
Next, on my rundown of the Best .357 SIG Handguns, a metal-framed, hammer-fired challenger…
3 SIG P229 — Most Accurate .357 SIG Handgun
Polymer-framed, striker-fired handguns have become the standard type for combat, law enforcement, and private self-defense. Impact-resistant thermoplastics are lightweight and impervious to corrosion, and striker mechanisms eliminate, or minimize, exterior protrusions and typically use fewer parts.
Balanced and precise…
However, some shooters prefer metal-framed, hammer-fired pistols, and there are a few reasons for this. First, a steel- or aluminum-framed handgun can feel more balanced in the hand; polymer-framed handguns tend to be top-heavy, even when the frame is reinforced. Second, the sometimes increased weight can more effectively absorb recoil — in a powerful weapon, like a .357 SIG, this can make the difference between “manageable” and “uncomfortable to fire.”
As for hammer-fired weapons, they tend to have a more crisp trigger press, especially in the single-action mode, allowing for more precise shooting.
Fortunately, there are still high-quality alternatives to striker-fired pistols, such as the popular SIG Sauer P220 series. The P229, a compact variant of the P226, is a short-recoil-operated, double-action/single-action (DA/SA), hammer-fired handgun. Introduced in 1991 to compete against the Glock 19, the P229 is similar in size and weight to the Austrian weapon but has an aluminum-alloy frame.
The P229 is available in three chamberings: 9mm Luger, .40 S&W, and .357 SIG. Unlike its predecessor, the P228, the P229 has a heavier machined stainless-steel slide to more effectively control the recoil of the more powerful cartridges.
- Barrel length: 3.89 inches
- Overall length: 7.08 inches
- Weight: 31.9 ounces
- Magazine: 10/12-round detachable box
The P229 does not have a manual safety catch. Instead, P220-series pistols have a decocking lever, located on the left side of the frame, above the magazine catch and forward of the slide stop. By depressing this lever, the hammer will lower safely on a chambered cartridge.
Of course, the word “safely” must be taken with a grain of salt regarding firearms. As practically any owner’s manual will assert, often in bold lettering — mechanical safeties can fail — therefore, it’s necessary to keep the muzzle pointed in a safe direction at all times.
As with the Glock series, the DA/SA pistol, with a decocking lever, is a simple design with few external controls.
As a DA/SA handgun, the customary method for carrying the P229 is with a round in the chamber, a full magazine in place, and the hammer down. The first shot is double action — i.e., pressing the trigger will both cock and release the hammer — and all subsequent shots will be single action as the reciprocating slide recocks the hammer.
In single-action mode, the trigger stroke is shorter and has a 4.4-lb break. Furthermore, the trigger reset is both short and positive, allowing for fast follow-up shots. The P229 has a longer, heavier 10-lb trigger pull in double action.
Like the Glock 31, which is comparable in weight, the P229 recoils sharply but linearly; there is minimal muzzle flip, but the rearward recoil can prove stout, depending on the load. The slide velocity of the .357-caliber variant is greater than that of the 9mm or .40-caliber P229, owing to the increased muzzle velocity and chamber pressure. Fortunately, the textured grip panels, serrated front strap, and grip frame height increase traction and controllability.
Dimensionally, the P229 is closer to the Glock 32 (and G19) than the Glock 31.
Sights and Accuracy
SIG Sauer firearms are generally known for being accurate, and this is equally true regarding the P229. At 25 yards, when fired from a bench rest, the P229 can achieve group sizes of 1.4–1.75 inches, depending on the ammunition. This is more than acceptable for a combat handgun and more accurate than any other weapon I tested.
The iron sights are the standard three-dot type, consisting of a front blade that you align with a rear notch. For improved low-light visibility, SIGLITE night sights, which substitute self-illuminating tritium, are available.
The short, light, single-action trigger break also contributes to its ability to print tight groups.
Reliability and Durability
SIG has a reputation for producing reliable, durable firearms. In the XM9 trials, the P226 experienced fewer malfunctions than the Beretta, and the SEALs swore by the M11 for years. For both wear and corrosion resistance, SIG applies the Nitron finish to its firearms. The company describes Nitron as a “metallic protective coating” that is an “extremely hard, microscopically thin barrier that protects metal finishes from corrosion and cosmetic damage.”
The SIG P229 has a standard magazine capacity of 12 rounds — three fewer rounds than the Glock 31 and one less than the G32 but three more than the Glock 33. The magazine catch is a horizontally sliding button located on the left side of the frame, under the decocking lever.
Up next, a small, discreet powerhouse…
4 Glock 33 — Best Subcompact .357 SIG Handgun
While the Glock 32 and P229 are among the best compact .357 SIG firearms available, there are few subcompact weapons in this caliber that compare with the Glock 33. Subcompact pistols in powerful calibers, such as the .40 S&W, .45 ACP, .357 SIG, and 10mm Auto, are controversial. By reducing the height, and thus available gripping surface, and weight in the interest of increasing concealability, you invariably sacrifice control.
However, if your priority is to carry more power than standard concealed-carry calibers afford in an ultra-compact package, the G33 is the best choice on the market in .357 SIG.
- Barrel length: 3.43 inches
- Overall length: 6.50 inches
- Height (including magazine): 4.21 inches
- Width: 1.26 inches
- Weight (w/ loaded magazine): 25.93 ounces
- Magazine capacity: 9-round detachable box
Introduced in 1998, the G33 is the .357-caliber variant of the Glock 26 (the so-called Baby Glock) and has a similar profile to the .40-caliber G27. Having a height of only 4.21 inches, it is exceptionally concealable, and its lightweight construction is convenient for daily carry.
Safety and Trigger Press
Like previous entries on this list, the G33 shares the same Glock trigger press, breaking at approximately 5.5 lb, and the Safe Action System is identical.
The G33 has a short grip frame, and it’s common for the little finger to curl under the magazine. As a result, acquiring a full-firing grip during the draw stroke can prove challenging, necessitating additional training. It can also exacerbate felt recoil considerably. For this reason, many shooters use magazines with extended base plates. This has the advantage of extending the front strap, allowing for the use of three fingers instead of two, and the capacity.
Sights and Accuracy
The sighting system in use in the G33 is the same as that of the G31 and G32, but it’s worth discussing the pistol’s accuracy. Although it has a shorter barrel and sight radius, this doesn’t appear to affect the pistol’s practical accuracy. At 25 yards, five-shot group sizes of 2.9–3.3 inches are possible. While not as accurate as the G31 or G32, the entire purpose of carrying a subcompact is for self-defense at extremely close ranges.
Despite its diminutive size, the G33 has a standard capacity of 9+1 using a flush-fitting magazine. It is also compatible with other .357-caliber Glock magazines, allowing for capacities ranging from 9–16 rounds.
