Comparing the Glock 43x to the Glock 43: In-Depth Analysis-MTR has holsters for them
MTR Custom Leather scored big time and got our hands on the all new Glock 43x and Glock 48 before they were released, which gave us the ability to get our hands on them and have holsters ready well before launch! We are excited to have a full lineup of holsters available for all of the SlimLine Glocks including the 43x:
A-2 Dual Carry
A-3A Tuckable Adversary
B-1A Slimline Deluxe Pancake Belt Slide
A-8 Paddle Holster
(Every holster from shoulder rigs, ankles rigs IWB, OWB can be made for the Glock 43X)
The Glock 43x not only features front cocking serrations but also features an nPVD finish vs the standard Gen5 nDLC finish found on the Glock 43. The verdict is out as to how the nPVD will stand up vs. the nDLC but hey, at least it looks nice…
HERE IS A RUNDOWN OF SOME OF THE MOST OBVIOUS CHANGES…
HEIGHT WITH MAGAZINE:
The Glock 43x has a height of 5.04″ vs the Glock 43 that features a height of 4.25″.
The change gives the shooter more grip length which allows for a more full grip and better control of the pistol.
The extended height allows another advantage over the Glock 43 which is magazine capacity. The Glock 43 comes with a flush 6 round magazine while the 43x holds 4 additional rounds bringing you up to 10 rounds with a flush magazine. When it comes to magazine capacity bigger is almost always better and the 43x is certainly delivering with the additional 4 rounds.
Many customers are expecting that Glock will be releasing an extended or higher capacity magazine in the future, but there is nothing official from Glock at this time.
