OK - I've run 530 Rounds through my UTC now, so I'm broken in with my first cleaning finished. On my last batch of 50 rounds shot, I had 2-3 FTFs. I believe this is due to the original magazines provided by LB. The mags were down to two rounds when the FTFs happened FWIW. The LB magazines are OK and a good cleaning should help, but higher level mags seem like a good idea to me. I would like to buy of couple of those type mags to go with the three factory mags and I should be good to go. Suggestions? I'm sure y'all have them. Thanks!!!!!
