The Glock 43 is a single-stack 9mm Luger subcompact pistol designed around concealed carry. At 1.02 inches wide and 17.95 oz. with an empty magazine, it disappears in most carry configurations. The gray Cerakote frame and black slide are the identifying visual features of this variant.

Detailed Features 

The G43 uses Glock's three-passive-safety system (trigger safety, firing pin safety, and drop safety) without a manual external safety lever. This means it's ready to fire as soon as you draw and grip it. The polymer frame is durable and contributes to the light carry weight. Fixed sights are low-profile and catch clothing less than taller aftermarket options. The aftermarket for the G43 is large: trigger upgrades, sights, mag extensions, and holsters are widely available. 
 

Usage 

The G43 is used almost exclusively as a concealed carry pistol. The slim single-stack design is the point. It fits in a pocket holster, AIWB, or IWB in most clothing without printing. The 6+1 capacity is the main trade-off for that slimness. It also works as a backup gun for duty carry. At the range it's a usable training tool, though the recoil is snappier than the larger G19.

The Glock 43 Gen 3 is one of the most discussed carry pistols in the market, and feedback is largely consistent across forums and review sites.

Concealability: The most cited strength. At 1.02 inches wide, it carries more comfortably than most 9mm options, and owners regularly mention being able to carry it in situations where a thicker gun wouldn't work.

Reliability: Glock's reliability reputation extends to the 43. Most owners report zero mechanical issues over thousands of rounds, which is the expectation at this price point and brand.

Ease of use: The Safe Action system with no external manual safety is frequently mentioned positively, particularly by new carriers who don't want to manage an extra step under stress.

Accuracy: Accuracy gets positive marks given the 3.39-inch barrel. Most owners can shoot it well enough for defensive distances, though it takes more practice than a full-size pistol.

Aftermarket: The availability of holsters, sights, triggers, and magazine extensions is a consistent selling point. Owners appreciate that the G43 ecosystem is mature and easy to shop for.

Capacity: The 6+1 capacity is the most common complaint. Buyers coming from double-stack pistols feel the trade-off, and some immediately add a Pearce or Shield Arms magazine extension. A few switched to the G43X for higher capacity in a similar size.

Recoil: The light weight makes recoil more pronounced than larger 9mm pistols. Experienced shooters adapt quickly; newer shooters sometimes find it harder to control for accurate rapid fire.

Grip size: Owners with larger hands note the short grip can be uncomfortable during extended sessions or when firing quickly. Adding a pinky extension helps most people.

Price: Some buyers feel Glock charges a premium for what is a relatively simple design. Most consider it fair given the brand's track record.
