Well, took it the range yesterday after installing the 21 lb spring from Wolf. Using S&B 230 FMJ, It still jammed with Colt and with the new Wilson mag I purchased. Installed the 19 lb last night and will try to get back to the range today. Probably should have tried the 19 lb first.
After talking to a retired military buddy, Iíll also be paying closer attention to my forward thumb placement. Itís possible I cloud be inadvertently contacting the slide causing friction and feeding issues.
Very frustrating as this Defender is one of my favorites and shoots so accurately for such a short barrel. Iíve had it for a couple years now and this issue pops up out of nowhere.
