What Reviewers Say
Quoted verbatim from YouTube reviews. Each link opens the video at the moment quoted.
It is not as easy to load this particular one because it's uh they had to put a block on it in order not to accommodate that many rounds so it feels a little bit weird.
I know it's a 100 yard gun I mean we got stupid accuracy over there basically my first shot.
I love it i love it that i mean i i don't know what else i expected from a glock it's fantastic it shoots fantastic it handles the recoil fantastic.
This obviously has a little bit more recoil but still the recoil i think is very very manageable considering the punch from 357c.
Three and a half three millimeters of very safe familiar travel and then a crisp break so excellent excellent glock trigger.
Customers Say
AI-generated insights derived from customer reviews and discussions on popular gun-enthusiast forums.
G31 Gen4 owners tend to anchor their feedback on Glock's reliability reputation and the .357 SIG caliber's velocity and flat shooting characteristics. The combination gets positive marks from competitive shooters and those who want high-velocity performance in a polymer-framed pistol. The Gen4 backstrap system is consistently praised for accommodating different hand sizes, and the 10+1 capacity in a full-size frame is seen as adequate.
Recoil and ammunition are the two recurring concerns. The .357 SIG produces noticeably more muzzle energy than 9mm, which some shooters find demanding in fast-paced drills. Ammunition availability and cost sit higher than for 9mm or .40, which affects how often owners can practice. Weight comes up occasionally, though at 23.3 oz the G31 is actually lighter than many comparable service pistols. Overall the G31 is seen as a capable, reliable platform best suited to shooters who specifically want the .357 SIG caliber.
