What Reviewers Say
Quoted verbatim from YouTube reviews. Each link opens the video at the moment quoted.
That's fun. That's fun to shoot when you up the start up in the power.
One thing about glock is the trigger pull it's a little bit spongy.
That's a good shooting round. You get up to 1150, it's still a really sweet shooter. Not not excessive recoil at all.
You notice you're getting some recoil with that. You can see it. I can feel it. That was probably the hardest recoiling round of the day, I would guess.
It's pretty easy to hold on target even with hot ammo.
Customers Say
AI-generated insights derived from customer reviews and discussions on popular gun-enthusiast forums.
The G20 Gen4 has a dedicated following among 10mm shooters, and the discussions reflect that.
The 10mm caliber is the biggest draw. Owners appreciate the stopping power for both self-defense and hunting applications, and 15+1 capacity is frequently cited as a strong point. Reliability holds up to Glock's usual reputation - most owners report consistent function across conditions. Accuracy gets positive marks.
Ergonomics are generally well-received, though some note the interchangeable backstraps don't fully solve the size issue for shooters with smaller hands. Recoil is a topic of honest debate: experienced shooters tend to appreciate the challenge, while newer shooters may find the 10mm round more demanding than .40 S&W or .45 ACP. Aftermarket support on the Glock platform is extensive - sights, triggers, holsters, and custom parts are all readily available. Ammunition cost for 10mm runs higher than 9mm, which matters for high-volume training.
