Has anyone tried to swap out the recoil spring for the M57? I know that a retaining pin has to be removed because the rod and spring is a single unit. I have read that standard TT33 springs can be used as a replacement. Reason I'm wanting to do this is because the slide doesn't lock back on the final spent casing, and when racking the slide on the first initial round, there does not seem to be enough tension to fully seat the round. I have two magazines and this situation occurs on both, not just one or the other. Thanks.
