Comparison: Glock 43X vs. Glock 19 Gen 5

1. Size & Concealability

The Glock 43X wins in terms of concealability. With its slim profile and lightweight frame, it’s easier to carry all day, especially for those who prefer inside-the-waistband (IWB) carry. On the other hand, the Glock 19 Gen 5 is still concealable but bulkier, making it more suited for open carry or larger-framed individuals.

2. Capacity & Firepower

The Glock 19 Gen 5 offers a higher capacity with a standard 15+1 rounds, compared to the 10+1 rounds of the Glock 43X. If capacity is a major factor for you, the Glock 19 is the better choice. However, aftermarket magazines (such as Shield Arms S15) can increase the 43X’s capacity to 15+1 rounds.

3. Ergonomics & Handling

Both pistols feature Glock’s signature reliability and user-friendly ergonomics. The 43X has a slimmer grip, which is ideal for shooters with smaller hands. Meanwhile, the Glock 19 Gen 5 has an improved grip texture, ambidextrous slide stop, and a slightly flared magwell, offering better control in rapid-fire situations.

4. Accuracy & Performance

The Glock 19 Gen 5’s longer barrel (4.02 inches) provides better accuracy at longer distances compared to the 3.41-inch barrel of the 43X. However, both pistols offer Glock Marksman Barrels (GMB) for improved rifling and consistent shot placement.

5. Recoil & Shooting Experience

Due to its larger frame and weight, the Glock 19 Gen 5 absorbs recoil better, making it easier to control for follow-up shots. The 43X, being lighter, has a bit more felt recoil but remains manageable for most shooters.

6. Customization & Accessories

Both models support aftermarket accessories such as night sights, red dot optics (MOS versions available), and upgraded triggers. However, the Glock 19 Gen 5 has a larger aftermarket support, making it easier to find parts, holsters, and modifications.
