The Glock 43 is a subcompact 9mm Luger semi-automatic pistol with a 3.4-inch barrel, 6-round capacity, and polymer frame. This version has a Tiffany Blue finish. At 17.9 oz unloaded it's one of the lighter carry options in the Glock lineup, and the single-stack magazine keeps the profile narrow.

Detailed Features 

The cold hammer-forged barrel uses polygonal rifling, which Glock uses across its lineup for consistent accuracy and easier cleaning. The polymer frame keeps weight down without sacrificing durability. Three passive safeties (trigger, firing pin, and drop) engage and disengage automatically as part of normal operation. 
 
The 3.4-inch barrel is short, which affects velocity compared to a full-size 9mm, but at the distances where a subcompact is most likely to be used that difference rarely matters. The 6-round flush magazine is the limiting factor for most owners. 
 

Usage Scenarios 

Concealed carry is what the G43 is built around. The slim grip and short barrel disappear under a t-shirt in most inside-the-waistband holsters. It works at the range for practice, though 6 rounds per magazine means a lot of reloads during longer sessions. Home defense use is feasible, though most owners with that as the primary goal would choose a higher-capacity option.

Owners of the Glock G43 Gen 1 in Tiffany Blue come at it from two directions, carry practicality and aesthetics, and both groups tend to be satisfied with what they got.

The finish is the first conversation. Tiffany Blue is unusual in the handgun market, and owners who chose it generally like that it stands out. It's a carry gun that doesn't look like every other carry gun.

The compact size is the most consistently praised functional trait. The G43 is genuinely slim, single-stack 9mm in a polymer frame, and owners report it carries comfortably throughout the day in a range of holsters and clothing. Concealment is not a struggle.

Reliability follows the standard Glock pattern. Most owners report no failures across varied ammunition, and that consistent function is a key reason people choose it for self-defense.

The 6-round capacity is the most common criticism, particularly from owners who compare it to newer subcompacts that fit 10+ rounds in a similar footprint. The G43 was designed before that generation of micro-compact pistols, and some buyers feel the capacity is now dated.

Trigger feel gets mixed marks. Glock's standard trigger is functional and consistent, but some shooters prefer a lighter or crisper break and look at aftermarket options fairly quickly.

Aftermarket support for the G43 specifically is narrower than for the G19 or G17, which limits customization choices compared to other Glock models.
