Forgive me if this has been addressed before. I purchased my NRM Series 80 Commander SS last week. I noticed that the barrel bushing has a small gap about the thickness of a fingernail were it covers the spring. I dont know how hard the bushing is supposed to come out when you field strip it but when I did it, it came out quite easily. Pushed down on the spring and turned it by hand. It seems to lock in snug but the gap where it covers the spring has me wondering as well as how easy it is to turn and take out the spring. Should I be worried?
