I've bought several of these and all work perfectly in my Ruger P95. Other than a metal base and two extra rounds you can't tell them from the original Ruger 15-Round mags that came with the pistol. They lock in solid, and lock the slide back after the last round is fired.
I have two of these that I've tested at the range that are used for HD ammo; the rest go out to the range frequently.
Greg Cote is great for having these in stock, and ships them quickly. Haven't had any issues at all, and he continues to be my first choice for magazines. Keep up the great work.
