Does Glock Make a .357 SIG?
Glock handguns are revered for their rugged reliability, ease of use, and wide availability across common calibers. One question we frequently get from customers like you is: “Does Glock manufacture pistols for the powerful .357 SIG cartridge?”
The answer is yes. Glock produces several models built specifically for the potent .357 SIG round. This article will cover everything you need to know about Glock’s .357 SIG pistol offerings and how this exceptional caliber stacks up against other popular defensive loads.
Glock's .357 SIG Trio: Models 31, 32, and 33
The .357 SIG caliber is offered in Glock's full-size, compact, and subcompact pistol models - giving you a choice for your specific needs.
Glock 31
The flagship .357 SIG is the full-sized Glock 31 with a 4.49-inch barrel length. This versatile duty pistol has a standard 15+1 round capacity and accepts higher capacity magazines. The medium-large grip frame provides ample space for a secure hold to manage stout recoil during rapid firing.
With the longest sight radius of the three models, the G31 excels as a self-defense sidearm and as a holstered cruiser carry gun.
Glock 32
Next is the G32 – the compact .357 SIG variant with a 3.78-inch barrel and short, 13+1 capacity grip able to conceal under light cover garments. Police officers and armed citizens gravitate toward the G32 as a powerful CCW pistol that still allows a full firing grip and 12+1 extended mags.
The 3.78-inch barrel does sacrifice some velocity yet produces impressive muzzle energy for the G32’s size.
Glock 33
Lastly, Glock produces the diminutive G33 subcompact single stack suitable for discreet carry. With a 3-inch barrel and short frame housing just 9+1 rounds, the G33 trades ammo capacity for lightweight portability.
Yet despite its small size, the G33 still churns out upwards of 500 ft-lbs of energy – proving the efficacy of the .357 SIG round in compact platforms.
Glock’s .357 SIG models offer full-size, compact, and subcompact sizes – all engineered to exacting Glock standards.
What is .357 SIG?
Jointly developed in the 1990s by Federal and SIG Sauer, the .357 SIG cartridge sought to improve on the 9mm Luger’s stopping power. Based on the .40 S&W case necked down to .355”, the .357 SIG drives bullets over 1350 fps – faster than standard 9mm loads. This gives it superior energy for exceptional penetration and efficacy.
The .357 SIG can match a .357 Magnum revolver's power with extra capacity.
Reasons to Consider a Glock .357 SIG
Assuming you can handle the moderately manageable recoil, Glock .357 SIG pistols provide tangible benefits for defense:
- Stopping Power: The .357 SIG hits hard, rapidly incapacitating threats - key for personal safety. Proper ammo helps balance penetration.
- Higher Ammo Capacity: The full-size G31 carries an impressive 15+1 rounds of .357 power – more than double that of a .357 revolver. Fast reloads keep more rounds available.
- Accuracy At Distance: Thanks to velocity and trajectory, the .357 SIG excels past 100 yards – an advantage over 9mm.
Anyone wanting .357 Magnum power with a semi-auto Glock's extra rounds may favor the hard-hitting .357 SIG.
FAQS
