Hi all. So I have a Colt 1911 MKIV Series 80 Combat Elite from about 1993. Was at the range today and the slide stopped locking back on the last round. Got home and took it apart to clean it and it looks like the slide lock broke, a little piece on the inside that contacts the magazine sheered off. A very small amount can barely see it. Any suggestions on where to source a good replacement part? Should I go with a genuine Colt part? Also what may have caused this to happen? Thanks in advance!!
