Chambered in 9x19 the G43x MOS features slide cuts designed for specific micro-optics and the GLOCK Slim Mounting Rail for mounting accessories. The G43X MOS has a short subcompact barrel length and a comfortably balanced, versatile compact-size grip with a minimal profile. It incorporates elements of the Slimline series such as the short trigger distance, a frame with a built-in beavertail as seen on the G43 and the G42, a reversible magazine catch. This model has the incredibly accurate, match-grade GLOCK Marksman Barrel (GMB) of the Gen5 series as well as the tough nDLC finish on the slide. The G43X MOS also features precision-milled front serrations. The slim magazine has an orange magazine follower for higher visibility and is specifically developed to ensure the 10 rds magazine capacity. Note: The G43X with the Modular Optic System (MOS) does not come with adapter plates.

Quick delivery from Bud's once I got my FFL dealer situation sorted. Love the feel of the 43X in my hand, nice weight, shoots flawlessly, installed night sights and ordered two after market 15-round mags, so good to go. Will be able to use stock 10-round mags if I need to lighten the weight a bit. After reading all the complaints about Glock triggers, the trigger on the 43X is quite decent w/ minimal take-up and a short re-set. Feel no need to change it out. Highly recommend.

Good pistol but only 10 rounds, need to buy after market mag to be 15 rounds and invest in high sights and the red dot you end in a $1,500 pistol(Glock come on), insted buy a hellcat pro comp.

I have.a PSA Dagger Micro and I wanted to compare it to the Glock 43 X MOS so I bought one. I took it to the range and ran a couple hundred rounds through it. It shot very well. After all the rounds my finger was a bit sore due to the trigger safety feeling sharp. I’ve qualified on a G 22 and a G 21 and neither trigger was an issue. The 43 X is definitely a much better made gun and for daily carry I’d feel more secure with the 43 X. The Dagger Micro has less felt recoil than the 43 X. My concern with the Micro is with the standard PSA 15 round mags I had jams and light strikes. Running the Micro with Glock 10 round mags I didn’t experience jams. Summing the guns up, the G43x will be a great carry weapon and the Micro will be a range tool.
