2011 slide doesn't go to the battery.

[cheby]

Occasionally, when I reload with a  fully loaded magazine, the first round from the new magazine doesn't go to the chamber completely. I'd fire the round in the chamber and then it happens. Sometimes I have to push the slide with my left hand  or it goes by itself with some delay.  It doesn't happen often but the last two occasions happened at the matches and annoyed me. The springs, both magazines and recoil, are newish. If the magazine is not fully loaded it doesn't happen. It happened with several magazines including mbx and svi with grams gutts.  Any idea? Something is dragging. Perhaps the gun/magazine was dirty. Perhaps the lips or?

I would try a new recoil spring . It's an easy first step. The one you are using could be weak.

What kind of ammo are you shooting?

Blue bullets.  I am pretty sure that FMJ would feed better in theory but I shot a lot of blue bullets for the last few years. Money talks

Mag spring, then look at mag height and extractor tension.

I just wondering if your ammo was on the weak side that could cause your problems.
