Very well designed and an awesome upgrade for my Glock 45. Gives it a new life, and a new purpose.
Best upgrade I’ve made to any of my pistols so far — turns a regular handgun into something that shoots like a little carbine.
My wife actually enjoys shooting now because the extra stability and lower recoil make it way less intimidating.
Swapped it between three different pistols in one range session and it worked perfectly on all of them.
I was surprised how light it feels while still adding real points of contact and reducing felt recoil.
