The Gen 3 Glock 19 and Gen 5 Glock 19 are both popular models, but the Gen 5 introduces several improvements and design changes. Here’s a breakdown of the key differences:
1. Frame & Grip Design
- Gen 3: Features finger grooves on the grip, which some shooters find uncomfortable.
- Gen 5: No finger grooves, providing a more universal grip that accommodates different hand sizes.
2. Trigger & Internals
- Gen 3: Standard Glock trigger with a heavier pull and slightly longer reset.
- Gen 5: "Glock Marksman Barrel" (GMB) and an improved trigger system with a smoother pull and shorter reset, making follow-up shots easier.
3. Slide & Finish
- Gen 3: Uses a traditional Tenifer finish, which is durable but can wear over time.
- Gen 5: nDLC finish (diamond-like coating), making the slide more scratch-resistant and corrosion-resistant.
4. Ambidextrous Features
- Gen 3: Right-hand dominant only (single-sided slide stop lever).
- Gen 5: Fully ambidextrous—includes a reversible mag release and ambidextrous slide stop for left-handed shooters.
5. Barrel Design
- Gen 3: Uses a standard polygonal rifling barrel.
- Gen 5: Glock Marksman Barrel (GMB)—improves accuracy with enhanced rifling.
6. Magazine Well
- Gen 3: Standard flat magazine well.
- Gen 5: Flared magazine well for faster and easier reloads.
7. Slide Stop & Take-Down Pins
- Gen 3: Single-sided slide stop lever; features two take-down pins.
- Gen 5: Ambidextrous slide stop lever; features one take-down pin for easier disassembly.
8. Overall Feel & Performance
- Gen 3: A time-tested, reliable design that many shooters still love.
- Gen 5: Smoother shooting experience, better trigger, and improved ergonomics, making it a preferred choice for many.
Which One Should You Get?
- If you prefer finger grooves, want a classic design, or live in a restricted state (CA still only allows Gen 3) ? Go with the Gen 3.
- If you want better accuracy, smoother shooting, and a modern design ? Gen 5 is the better option.
Both are excellent choices, but the Gen 5 brings noticeable improvements in ergonomics, accuracy, and durability.
