This is a full sized pistol and comes with 3 different grip back straps small, medium and large to accommodate all hand types. I don't think you'll have an issues it's a pretty big pistol and if for some reason it's to small I'm sure they have magazine extensions to increase the grip size. Hope this helps.

it fits large hands well

Its just slightly taller then a Glock17, handgun hero is a great site to compare pistols side by.

Riley, I have two of this model and have large hangs and it fits large hands just fine. No issues and the grip separates the fingers for a more natural feel & better control when firing. Cheers and stay safe!
