Glock 48

The Glock 48 pairs the slim 43X grip with a longer G19-length slide, providing improved sight radius and barrel length while maintaining the slim profile. The 4.17-inch barrel offers slightly better velocity than the 43X's 3.41-inch barrel, and the longer sight radius aids accurate shooting, especially for iron sight users.

Like the 43X, the 48 now ships standard with Glock's factory 15-round Slimline magazine for 15+1 capacity, and it accepts the same Shield Arms S15 mags as an alternative. The longer slide does increase overall length but doesn't significantly impact concealment since the grip is what typically prints during carry. Many shooters prefer the 48's balance and sight picture over the shorter 43X.

For shooters who prioritize accuracy and longer sight radius but still want the slim 43X-series profile, the G48 offers the best of both worlds. The additional slide mass also contributes slightly to reduced felt recoil.
