Looks like a great sidearm. Best of both worlds for a full sized Glock.
My G17 fits my hand perfectly. So, I would imagine if your hands are medium to large that the G17 lower will feel very comfortable w/out added grip tape or anything. The 19 is great as you know, but this new G45 sounds like true Glock perfection. A good move on Glocks behalf and not for just the sake of marketing.
Certainly a nice and thoughtful addition for your dept. as well. After a trip or two to the range please post your review. I’d love to hear your findings.
