The Glock 19 doesn't need much. But the right few parts make a real difference.
Here's the order we'd upgrade a Glock 19 in, starting with what matters most for carrying it every day, then what makes it better at the range. Everything below is made for the Glock 19 (and its siblings, where noted).
1. A Holster You Trust
The single most important accessory. Pick by how you carry:
- Concealed, inside the waistband: the ORPAZ EVO Level II IWB has a thumb lock right where your hand lands on the draw and a trigger window to check the pistol's status.
- Outside the waistband, every day: the ORPAZ Level II OWB paddle holster gives you a thumb lock, adjustable retention and a paddle that comes off in seconds.
- With a weapon light: the ORPAZ DELTA takes different lights (or none) through swappable adapters, and the Fobus Level 2 duty holster locks the pistol with a thumb-released rotating hood.
Not sure which retention level you need? Our Fobus vs ORPAZ guide walks through it.
2. Night Sights
Factory Glock sights disappear in the dark, which is exactly when a defensive pistol is most likely to be used. Tritium sights glow without batteries:
- Meprolight Tru-Dot for standard-frame Glocks: three tritium dots, full set or front only.
- Meprolight Tru-Dot Adjustable: same idea, with a rear sight that adjusts for windage and elevation.
More on how tritium works in our night sights guide. Note: tritium sights ship to US addresses only.
3. Two More Rounds
The IMI Defense +2 magazine extension replaces the floor plate and adds two 9mm rounds, plus room for your little finger. Check your local capacity rules first.
If you'd rather keep a Glock 19 and use longer Glock 17 mags at the range, the IMI grip extender sleeve fills the gap so the grip feels full-size.
4. Small Parts, Big Comfort
- Recover Tactical charging handle: more to grab when you rack the slide, with no snag points.
- IMI lanyard loop plug: closes the open grip and gives you a lanyard point.
5. Turn It Into a Carbine
For the range, a conversion kit is the biggest upgrade of all: a stock or brace, rails for a red dot and light, and a far steadier hold. Drop the pistol in, lock it, go.
- CAA Micro RONI: CAA's flagship, with the most rail on top.
- CAA MCK Gen 2: the value pick, suppressor ready.
- CAA MCK Gen 3: works with a slide-mounted red dot.
Comparing them? See Micro RONI vs MCK.
In the US, a shoulder stock on a pistol may require NFA/SBR registration. Check your local laws.
