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.
The Glock 31 Gen 4 in .357 SIG gets mixed but generally positive feedback from experienced pistol shooters.
The caliber itself is the main topic. .357 SIG is praised for its velocity, flat trajectory, and terminal performance, particularly by those familiar with it from law enforcement context. The 15+1 capacity is considered a strong point. It packs more rounds than most revolvers without making the gun larger. Build quality and durability draw the usual Glock praise; owners report the gun runs reliably and handles hard conditions without issue.
The criticisms are predictable for the caliber: .357 SIG ammunition costs more than 9mm or .40 S&W and is less available at retail. Recoil is snappier than 9mm, which some find manageable and others need more range time to control well. Holster compatibility can require checking since the G31's barrel length differs slightly from some other Glock models. Trigger feel is standard Glock, which experienced shooters accept but some prefer to modify.
