Iv been pursueing this on my G20 for some time, even on 10mm forum. Ive found if I can lock both wrists and force recoil to take arms up, it may feed properly. Have found that cleaning and drylubeing magazine will decrease #s of FTFs. This seems to occur only with hunting loads(>700FP KE) , light loads behave pretty near 100%. Im comfortable letting the pistol recoil and can bring it back on target in less than1sec. Limp wrist-i dont really know. I dont find fighting to "lock" everything tightly is particularly conducive to accurate shooting. I would rather find a way to have this gun function "normally" with the heavy loads.
The failures are almost always the same with the front of the slide riding up on the case body ahead of the extractor groove. The bullet is trying to enter the chamber but the slide has it trapped midbody. A stronger mag spring makes a slight improvement, but they continue to occur. 3 levels of recoil spring dont help if at all. The problem seems to be that with the heavy loads the slide velocity is fast enough that the next round in the magazine cant rise fast enough to get in front of the slide and gets trapped.
Any ideas?
