Glock
Glock pistols have earned a reputation for reliability, simplicity, and near-zero maintenance that has made them the most trusted handgun on the planet. From the full-size Glock 17 to the slim Glock 43X and the optics-ready Glock 19 MOS, every model shares the same striker-fired Safe Action system that cycles reliably in any condition. Whether you’re buying your first handgun or adding another Glock to the safe, Impact Guns carries the full lineup—new Gen 5, Gen 6, and V-Series models—across all major calibers.

Why Glock Dominates the Market
Introduced in 1982, Glock’s polymer-frame design was considered radical—today it’s the standard every other manufacturer competes against. The Safe Action trigger system fires only when the trigger is deliberately pulled, eliminating the need for an external manual safety while keeping the action consistent shot after shot. Law enforcement agencies, military units, and competitive shooters worldwide rely on Glocks for one simple reason: they work every time. With fewer than 35 components, there’s very little that can go wrong.
Glock Models at a Glance
The Glock lineup is organized by frame size and caliber. Full-size models like the G17 (9mm) and G21 (.45 ACP) offer the longest sight radius and highest capacity. Compact models—the G19, G23, and G32—balance capacity with concealability. Sub-compact and slimline models including the G43, G43X, and G48 are built specifically for everyday carry. The 10mm G20 and G29 serve hunters and those needing hard-hitting performance in the field. The G34 and G35 are purpose-built for competition with extended barrels and lighter triggers.
Gen 5, Gen 6, and V-Series—What’s the Difference?
Gen 5 brought flared magwell, ambidextrous slide stop, and removal of finger grooves for a more universal grip. Gen 6 builds on that with refined tolerances and updated internal components. The V-Series (Voyager) represents Glock’s value-oriented lineup—same proven Safe Action internals at a more accessible price point. MOS (Modular Optic System) variants add a factory-milled slide for direct red dot mounting without an adapter plate, which has become increasingly popular for duty and carry use.
Choosing the Right Glock Caliber
9mm is the overwhelming choice for most buyers—lower recoil, higher capacity, and modern defensive ammunition that matches or exceeds older larger-caliber loads. The .40 S&W G22 and G23 remain popular with shooters who prefer that caliber’s terminal performance. .45 ACP G21 and G30 models serve those committed to the classic cartridge. 10mm G20 and G29 offer serious power for hunting or bear country carry. The .380 ACP G42 is the smallest Glock made and a natural choice for deep concealment.
Glock for Concealed Carry
The G43, G43X, and G48 are Glock’s dedicated carry pistols. The single-stack G43 holds 6+1 rounds of 9mm in a package thin enough for ankle or pocket carry. The G43X and G48 share the same slim frame with a longer grip that accepts 10-round magazines—the G48 adds a longer slide for improved accuracy at distance. All three accept Shield Arms S15 magazines for a significant capacity upgrade. For a slightly larger carry gun with more rounds, the G19 compact remains the most popular concealed carry pistol in the country.
