I took my Springfield Armory Stainless Loaded to the range yesterday and ran maybe 250 rounds through it. Took it home, took it apart, cleaned it, put it back together. Now it occasionally wants to bind up while feeding a round from the magazine into the chamber. It's never done anything like this before and I certainly didn't do anything different than I've done in the past as far as disassembly, cleaning, or reassembly, but obviously something isn't working right. What the hell did I mess up? Any suggestions?
