Glock 48 Overview
The Glock 48 is a Slimline 9mm with a 4.17-inch barrel. GLOCK says it is of similar length and height as the G19, but with a reduced width for better carrying comfort.
Current models include the GLOCK Slim Mounting Rail, and the G48 MOS version is cut for micro red dots.
Glock 19 Overview
The Glock 19 is GLOCK’s best-known compact 9mm, with a 4.02-inch barrel and a double-stack 15-round magazine.
GLOCK describes the G19 as a popular choice for everything from everyday carry to professional use. The current Gen6 version is optic-ready from the factory.
Size and Concealability
Based on GLOCK’s published specs, both pistols are 7.28 inches long and 5.04 inches tall. The Glock 48 is about 0.24 inch thinner and about 1.8 ounces lighter than the G19 Gen6.
Interestingly, the 48 also has a slightly longer barrel, at 4.17 inches versus 4.02 inches. For most carry buyers, the thinner frame is the difference that matters.
Capacity and Magazines
The Glock 19 holds 15 rounds as standard. GLOCK’s G48 product page lists a 10-round slim magazine, and in April 2026 GLOCK announced that G48 pistols will ship standard with new 15-round, metal, double-stack Slimline magazines starting in May 2026.
Check the listing for the exact magazine your G48 ships with. Glock 48 and Glock 19 magazines are not interchangeable, because the 48 uses Slimline magazines.
Browse options like the ETS Glock 43X/48 magazine or the Magpul PMAG 15 GL19. Magazine capacity limits vary by state — always check our ammo and magazine laws guide.
Range Use and Shootability
With the same length and nearly the same barrel, the two pistols have a similar sight radius. The wider G19 grip gives some shooters more to hold onto during long range sessions.
Many shooters with smaller hands find the thinner G48 grip more comfortable. Try both if you can before you buy.
