I've got an Ultra Tac II - 3" barrel - very steep feed ramp.
It's got about 200 rounds thru it. It has a failure to feed problem. About a third of the time the last round in a magazine will not feed all the way. It feeds far enough that a quick pull and release on the slide chambers the round. The recoil spring is the stock Kimber 18# that comes from the factory.
The problem is not the magazine. The problem occurs with all mags I've got which include Kimber, Wilson and Chip McCormicks (10 mags total - 3 of which are 7 rounders). All those same mags (except the 7 rounders 'cuz they're too short) function perfectly in my full size S&W 1911 (takes 8 round mags).
All ammo fired is handloaded. Depending on the load OAL runs 1.19 to 1.25. The FTF problem exists regardless of the OAL. All though the problem exists with all loads it occurs more frequently with hotter loads. All handloads function perfectly with no FTF's in my full size 1911.
ASIDE: The gun doesn't like lead bullets (RNFP) - those will occasionally misfeed regardless of position in the mag.
My question for you experts on 1911 actions is what could the possible causes be and what are the solutions.
