The Glock 43 is one of the most popular single-stack 9mm pistols out there, and for good reason. It's thin, light, and easy to carry. But if you run a G43, picking up a spare magazine just makes sense. The KCI USA KCIMZ053 gives you exactly that at a price that makes grabbing two or three easy to justify.
The construction here is more thoughtful than it might look at first glance. The body combines a hardened steel insert encased in polymer, so you get the rigidity and feed-lip durability of steel with a polymer shell that resists dents, dings, and the kind of deformation that can happen when magazines get dropped on concrete repeatedly. Inside, a stainless steel wire spring and anti-tilt polymer follower work together to keep rounds feeding consistently from first round to last.
A few practical details worth knowing: the rear of the magazine has numbered witness holes so you can do a quick round count at a glance without having to rack the slide or drop the mag. The baseplate is removable for easy field stripping and cleaning. And the included grip extension gives your pinky finger somewhere to land, which makes a real difference in control on a pistol this compact.
The flush-fit profile keeps the mag sitting tight against the grip frame, which matters when you're carrying concealed and want clean lines without anything catching on your cover garment. KCI backs this magazine with a limited lifetime warranty on manufacturing defects, which is a good sign for a budget-friendly aftermarket product.
This is a single magazine, sold in black matte finish, and fits the Glock 43 chambered in 9x19mm. Not manufactured or endorsed by Glock, Inc.
Yes, the KCI KCIMZ053 is designed specifically for the Glock 43 chambered in 9x19mm. It is precision-engineered to fit the G43 magazine well and function with the factory controls. Keep in mind this is an aftermarket product and is not manufactured or endorsed by Glock, Inc.
It does. The KCI Glock 43 magazine includes a built-in grip extension at the base, which gives your pinky finger a place to rest. For a compact pistol like the G43, that extra bit of grip surface can noticeably improve control during shooting.
The body uses a hardened steel insert encased in a polymer exterior. This combination gives you the rigidity and feed-lip durability of steel while the polymer shell helps protect against dents and deformation from everyday handling and the occasional drop.
KCI USA covers their magazines with a limited lifetime warranty against manufacturing defects. If the magazine fails due to a material or workmanship issue, KCI will repair or replace it at their discretion. Normal wear and misuse are not covered.
Absolutely. The flush-fit design and compact profile make it well suited for concealed carry use with the Glock 43. The numbered witness holes let you confirm round count quickly, and the removable baseplate makes cleaning straightforward after range sessions.
The KCI mag uses a stainless steel wire spring, which holds up well to the repeated compression of keeping it loaded. Stainless steel resists corrosion better than standard carbon steel springs, making it a reasonable choice for a carry magazine that may stay loaded for extended periods.
