Hi,

I put the screw back in just to where I see it not touching the slide stop (a little light can be seen). In this spot it also doesn't seem to impede the spring from moving either. I noticed a little wear on the end of the screw where it has been rubbing the slide stop, so maybe this was part of the issue. I greased the screw head to smooth it as well as the slide stop pin and the barrel center, all greased with flitz grease. It does seem to have a stronger downward push now than it did before. If you push it up and let it sit it will try to move down slowly on its own and it you retract the slide (removing pressure on it) it will jump down with a small snap, so hopefully this will solve the issue. An empty mag does indeed push up on it properly as well.

Thanks,

Alan
