Just bought a XC 1 clone. Very well made and bright light but I can't mount well on my two G19.
It has a small locking pin in the rear right side but I have not a locking hole in my Glock frame.
I searched for real steel Glock pics on the Net and I can't find any hole.
Anyone can suggest me if is better to drill a small hole in the frame ora to sand down the pin?
