I picked up my black SR9c this past Monday. Put 50 rounds of cheap Federal 117g through it right there at the gunshop's range - it went bang every time. I cleaned it lightly and took my CHL renewal class the next night and was very pleased with the groupings during the 50-round qualifying, but did have a single FTF (using Remington UDC 117g). Cleaned it again. Yesterday, I put just 20 rounds through it from the same Remington box and got two more FTF. Last night I noticed that the breech face was coated with a brass residue, so I used Hoppes #9 on it with a toothbrush. This morning, I went back to the range and put the last 30 Remington rounds through it without a problem, then 100 rounds of Winchester WB with nary a problem. That's 250 rounds from three manufactures in five days and three FTFs. I think it's breaking in nicely. My groups are looking better/tighter and the thing puts a grin on my old face. It's currently loaded up with Hornady Critical Defense 135g. Wish I'd had it with me this morning to put a few through and see how it would work. I'm not expecting any problems with these (but dang, they're almost 4x the cost!).
This is my first semi, except for a Colt Challenger .22 and my faithful Keltec P3AT. Lots more parts in this one. I'm wondering if I may have caused some of the brass transfer onto the breech face when I put a very light wipe of gun oil onto it during the Wednesday cleaning. Any experience there?
