Looking to carry a Glock but not sure whether to go with the slimmer Glock 43X or the time-tested Glock 19? These two pistols dominate the concealed carry market for good reason—but they’re designed for different priorities. In this post, we’ll break down everything you need to know to decide which one fits your needs best.
Size and Carryability: Slim vs. Compact
| Specification | Glock 43X | Glock 19 Gen5 |
|---|---|---|
| Barrel Length | 3.41 inches | 4.02 inches |
| Overall Length | 6.5 inches | 7.28 inches |
| Height | 5.04 inches | 5.04 inches |
| Width | 1.1 inches (slide) | 1.34 inches (slide) |
| Weight (Unloaded) | 18.7 oz | 23.6 oz |
| Capacity | 10+1 (standard) | 15+1 (standard) |
The Glock 43X is noticeably slimmer and lighter, making it much more comfortable for all-day concealed carry—especially in appendix or IWB configurations. It’s ideal for folks with smaller hands, or those who value discretion above capacity.
The Glock 19, while still considered compact, is more of a do-it-all pistol. It’s slightly chunkier and heavier but brings higher capacity and better recoil control.
Capacity and Magazine Options
Out of the box:
-
Glock 43X comes with 10-round single-stack magazines.
-
Glock 19 ships with 15-round double-stack mags (Gen5 also supports Gen3/4 mags).
BUT—the aftermarket changes the game:
-
Add Shield Arms S15 magazines to the Glock 43X and you get 15+1 capacity in a slimmer frame—matching the Glock 19’s capacity while keeping the slim profile. Just make sure to upgrade the mag catch to metal if you go this route.
Recoil and Shootability
The Glock 19 is easier to shoot quickly and stay on target with, thanks to:
-
Slightly longer sight radius
-
Heavier weight to soak up recoil
-
Fuller grip that allows more control
The Glock 43X is snappy by comparison, but manageable. It’s optimized for carry, not extended range sessions. If you're a newer shooter or planning to train frequently, the Glock 19 offers a more forgiving experience.
Concealed Carry Comfort
If daily carry is the #1 goal, the 43X feels like it disappears on your belt. The slim slide, lighter weight, and compact dimensions are hard to beat for comfort—especially during hot southern summers when you're wearing less.
The Glock 19 can still be carried concealed (millions do), but it takes more commitment: the right belt, holster, and wardrobe considerations. It’s also more likely to print in tighter clothing.
Optics and Accessory Support
-
The Glock 43X MOS and Glock 19 MOS models both support red dots, but the 19 is compatible with a wider variety of optics out of the box.
-
Both models support lights and lasers, though the 43X has fewer options due to frame size and rail limitations.
When it comes to holsters, mag carriers, and upgrades—both models have full aftermarket support thanks to Glock’s popularity.
Price & Value
Pricing is surprisingly close:
-
Glock 43X MSRP: ~$480–$550
-
Glock 19 Gen5 MSRP: ~$600–$650
Considering the Glock 19 gives you more capacity and versatility, it’s arguably the better value—unless carry comfort is your top priority.
Final Verdict: Which Glock Is Right for You?
Go with the Glock 43X if:
-
You prioritize deep concealment and daily comfort
-
You want a slimmer profile with optional 15+1 capacity (via S15 mags)
-
You prefer a minimalist EDC setup
Choose the Glock 19 if:
-
You want a versatile gun for carry, training, and home defense
-
You shoot frequently and want easier recoil control
-
You want more out-of-the-box capacity and accessory support
