Glock 21 Fail to Feed
I have a customers glock 21 w/ a KKM barrel that will not feeds the last round in a 10 RD or 13rd mag. This only happens with 200gr +P ENFJ federals. He can run white box 230gr Winchesters FMJs through the gun all day with no issues. I tested the gun w/ the ENFJs and I have had the same results. Each and every last round will not even attempt to chamber(white box win works fine). I even took both mags apart, cleaned them with power blast & replaced the mag springs. What gives?

This is just a guess -
Is the feed-ramp and subsequent chamber on the KKM barrel different than stock? Meaning, is the angle of the ramp different or longer? Or is the 6 O'Clock position in the chamber less "shallow" at the rear part than that of the stock barrel?
Second - what is the OAL of the rounds that don't feed? Does it differ from those that do, etc.?
My 21 had issues once with feeding the "old-style" Hydra-Shoks; those with the sharp shoulder. When Federal finally changed to a rounded shoulder, the gun fed them fine. The same "old-style" bullet also bound up in several s&W 645's and 4516's, and even a Sig 220 or two - all of those guns being very reliable designs, much like the 21.

Re: Glock 21 Fail to Feed
It's probably the magazines springs. Try it using Wolf plus 10% magazine springs. Keep in mind when you install new magazine springs you should leave the weapon fully stoked minus one round for at least 24hrs before using it for carry purposes. Also you never want to fully load the magazine, you should always down load it by one round. I believe this will solve your problem. Good luck.
