About This Firearm
The Glock G43 is a single-stack striker-fired 9mm built for concealed carry. Glock still lists it beside the wider Slimline pistols. Its magazine stacks 6 rounds in one column, which holds the gun to 1.06 inches across and 4.25 inches tall, and a molded beaver tail lets the firing hand sit high on the grip.
One flush magazine, a cleaning set, a cable lock and a lockable case come in the box, so a spare magazine is bought separately. Nothing on the grip adjusts, since the Slimline frame takes none of the beavertail backstraps a Gen5 frame does. The slide has no optic cut and the frame has no accessory rail, so a red dot or a weapon light means a different pistol. There is no manual safety, and three automatic mechanical safeties sit inside the fire control instead.
If you're cross-shopping, the Glock G43X puts the same 3.41-inch barrel and slide on a grip 0.79 inches taller, which gives the little finger somewhere to land, and it brings two magazines in the box at 18.7 oz. The Sig Sauer P365 matches the G43 on width, comes in lighter at 17.8 oz, and fits 10 rounds into a grip 4.3 inches tall. Both hold more than the G43, whose grip is 4.25 inches tall.

Strengths & Limitations
- The grip texture is aggressive and the magazine catch is enlarged, so the thumb reaches it without the hand shifting.
- A cable lock ships with the pistol in the USA, which covers locked storage without another purchase.
- The controls are a trigger, a slide stop and a magazine catch, with no safety lever or decocker to work under stress.
- A spare magazine has to be bought separately.
- The grip ends above the little finger, and no extended floorplate comes in the box.
- Reversing the magazine catch takes a field strip and a small screwdriver, and New Style magazines are required once it sits in the left-hand position.

Frequently Asked Questions
How does the Slimline grip differ from a Gen5 grip?
A Gen5 frame comes with beavertail backstraps that add 2 or 4 mm of frame circumference. The Slimline frame has one fixed circumference with the beaver tail molded in, so hand fit is whatever the frame gives.
How often does Glock say to clean it?
Before the first time it is fired, after every time it is fired, whenever it has met rain, dust, salt water or a drop, and at least once a year. Glock also warns against over-lubricating, because excess oil collects unburned powder.
Can reloaded ammunition be used in it?
No. Glock's instructions rule out reloaded, remanufactured and handloaded ammunition, and the caliber the pistol is chambered for is marked on the barrel.
