    My mag fell out my gun the first day at the range, I bought gorilla duct tape and it actually works ! One piece of tape gets the job done, I wrote a bad review but I take it back lol definitely 5 stars if you use a piece of tape !

    Mag would not lock into place, easily falls out while shooting. I wouldn’t recommend ordering this at all.
