When I took my new sr40c to the range I had several (3 or 4 in the first 100 rounds) failure to feed issues, not confined to a specific ammo. After thorough cleaning I went back to the range and fired about another 200 rounds, and had only a single failure to feed issue (with Remington 180 gr). I'm wondering if the total I have fired (about 300 rounds) is still not enough to consider the gun broken in, or should I be thinking of sending the gun to Ruger? I was planning on using this gun as a primary carry gun (when not in Illinois), and the thought of a FTF is disconcerting (although it never happened on the first round in a mag, usually on the 6th or 7th round of a mag loaded with the full 9 rounds).
