The difference between the Glock 43 and 43X is in the size of the grip. The Glock 43X has the same size slide and barrel as the 43, but it has a prolonged grip. That means it’s larger than its cousin and can hold a magazine with 10 rounds. Barrel length remains the same as 43, and overall length is extended to 6.5 inches. It has significant elements of the Gen 5 and Slimline series, like nDLC finish, the short trigger distance, built-in beaver-tail, a reversible magazine catch, and Glock Marksman Barrel. It doesn’t have finger grooves, but has well designed front and rear slide serrations. This front slide serrations are innovative and haven’t been seen on the Glock handguns before. The longer grip provides more solid grasp and makes drawing, holding, and aiming easier for the user. It’s suitable for both right-handed and left-handed shooters, and perfect for hidden carry.
