Ruger PC 9 mags are pretty much junk. I dropped mine, fully loaded.. My Fault, not theirs.. The base broke and these parts are not serviced by Ruger. So I am out a close to 50 bucks for a new one. To make bad matters worse, they sent the wrong one. Almost 3 week now and I have a paper weight gun, because the mag is junk! User's recommendation: Change to Glock mag well, and their mags. or avoid Ruger products.
