Moving from a Glock Gen 5 to a Gen 6 creates an obvious question for anyone who already owns aftermarket accessories: how much of the existing setup can be reused?

Magazine extensions are among the most popular upgrades for Glock pistols because they can improve both shooting comfort and magazine capacity without permanently modifying the firearm.

One of the biggest advantages of owning a Glock is the enormous aftermarket support available for nearly every model. While trigger kits, barrels, and recoil systems often get the most attention, they also change how the pistol operates internally.

The Glock Gen 6 platform introduced meaningful updates to its internal geometry while retaining much of the familiar Glock ergonomics shooters have trusted for years.

The Glock 43X and Glock 48 are among the most popular slimline Glock pistols, and for good reason. They share the same grip frame, magazine design, controls, and overall handling characteristics while offering two slightly different approaches to concealed carry.

The Glock Gen 6 arrives with several improvements over previous generations, including updated ergonomics, refined controls, and an improved optics-ready system. Even so, many owners begin looking at aftermarket upgrades almost immediately.
