I have posted several messages in recent months regarding problems with my P-11. It will not feed Winchester white box fmj and jams from time to time with UMC. After talking to Cliff at KT, I sent the slide to Florida. I got it back in about 10 days. They replaced the barrel and apparently the recoil springs, which seem to be stronger.
I went out yesterday and found that the replacement parts do not seem to have made any difference. I concentrated on holding the pistol rigidly to avoid "user error." But to no avail. I have given up on the Winchester ammo but will try again with the UMC. Perhaps this pistol just isn't the right one for me. I have found my P-32, bought the same day as the P-11, to be very reliable with several kinds of ammo.
I have sets of stronger springs from Wolff but doubt that they would help what seems to be mainly a failure to extract rather than a failure to feed. With the white box fmj, I typically have a jam with the spent shell still in the chamber and the new round stuck below it. I suggested to Cliff that I might have a problem extractor but he apparently didn't think so. The white box round is slightly longer than the UMC and this may be the problem.
