Glock G48 Slimline 9mm – 4.17" Marksman Barrel, Black nDLC Slide, 10+1 Capacity
The Glock G48 Slimline brings the proven reliability of Austria’s most popular duty pistol into a thinner, easier-to-carry package. This pre-2021, non-rail variant features a matched-number slide, barrel, and frame, a cold-hammer-forged Glock Marksman Barrel, and front and rear cocking serrations—all in a handgun that meets Canada’s 106 mm minimum barrel requirement while keeping a G19-length sight radius.

Built around Glock’s Slimline frame, the G48 measures only 1.10 inches wide yet offers a full-length grip and 10-round magazine. The glass-fiber-reinforced polymer frame carries Gen5-style stippling for positive control without adding bulk.
The 4.17-inch Glock Marksman Barrel uses hexagonal rifling for consistent bullet seal and easy cleaning. Cold-hammer-forged steel construction promotes durability, while the longer barrel maintains muzzle velocity comparable to larger service pistols.
Its black nDLC slide wears both front and rear serrations for confident manipulation. Standard polymer white-dot sights deliver a clear sight picture, and the reversible magazine release accommodates right- or left-handed shooters.
Internally, Glock’s Safe-Action system combines a 5.5-lb trigger pull with a central safety tab and striker block, providing a consistent break on every shot. Austrian proof marks verify factory testing and origin.
