I went to the range today with my SR1911 LW Commander and was faced with the same situation that I had last week. I reloaded about 200 rounds using CCI primers and again this week, I had almost 75% of them that were failure to fire. I am getting good firing pin hits but they don't go off. I pull out the mag, eject the round for inspection, re-insert the round into the mag and try again. The second time they will fire. I also use Winchester primers and have had only 1 FTF. The firing pin is hitting the primers hard but the CCI primers just will not fire the first time. A year ago, I think, I talked to CCI factory rep. and he told me that they had changed the anvil inside of the primers they now produce. At that time I was shooting a Gen 4 Model 19 Glock (which I don't have presently) and the factory rep. told me that Glock had problems with light strikes. I know my firing pin is striking the primer hard enough but it's almost as if you have to rotate the round to make it ignite. Is anyone else experiencing any problems with CCI primers?
