too bad you didn't know about this board then. Kimber had a short run of pistols with problematic slide stops. You were changing the wrong parts, it wasn't the magazines.squid8286 said:I have had several Springfields over the years, and they all were good pistols (save one). I traded a friend a Sig 220 for an early model Kimber several years ago. It was accurate and reliable, but the slide failed to lock back at least half the time. I tried all kinds of magazines - same problem. I sold it a few months after I got it. I managed to get the Sig back from my buddy about six months ago. I won't be trading it off again. I have never had the desire to own another Kimber after that first one.
