The Glock 19 is the compact 9 mm that many owners carry every day and shoot at the range on weekends. Its shorter grip and slide make a few parts different from the 17, so this page shows what fits the 19 and its crossover sibling, the 19X.
Carry and range sights
For a carried 19, tritium sights glow at night; for range use, fiber optic and LPA adjustable sets are faster. MOS slides take co-witness heights if you add a dot. The full choice for this size is in Sights for Glock 19, both MOS and classic.
Red dot
A MOS 19 swaps its cover for a plate; Optics ready plates for Glock 19 sorts them by footprint. Older non MOS slides use the rear sight slot instead, with mounts from Red dot mounts for Glock 19.
Grip and reload
Separate adhesive grips and magwells exist for the 19 gen 5 and the 19X, in Grips for Glock 19 and Magwells for Glock 19. Base pads add one or two rounds without making the gun much harder to conceal; see Base pads for Glock 19. The 19 also has its own frame mount, in Frame mounts for Glock 19.
Frequently asked questions
Do 17 magwells fit the 19?
No. The 19 gen 5 and 19X have their own.
Will a frame mount fit my holster?
It sits on the dust cover; check that your holster has room before fitting.
