When it comes to concealed carry, Glock doesn't play games—and neither should you. Two of the most talked-about pistols in the Glock Slimline series are the Glock 43 and the Glock 43X. Both have their fanbases, both pack a serious punch for their size, and both are built with the legendary Glock reliability. But which one is right for your everyday carry setup?
We’re breaking it down—side by side, spec for spec, and real-world performance—so you can decide which one earns a spot in your holster. Let's go.

Glock 43X: Slimline With More Firepower

Double the mag capacity over the G43
-
Longer grip = better control

Final Thoughts: Which Glock is Right for You?
If maximum conceal ability is your priority and you’re okay with 6+1, the G43 is still a top-tier choice. But if you want more rounds, better grip, and optics-ready options, the G43X delivers without compromising on slim carry.
Whichever you choose, you’re getting Glock’s legendary durability, reliability, and performance. And guess what? Moriarti Armaments has both models in stock and ready to ship.
Pro Tip:
Looking to push capacity even further? Consider Shield Arms S15 mags with the 43X for a whopping 15-round setup in a slim frame. Just don’t forget to swap in a steel mag catch!
