So, after feeding it about 900 rounds, i've noticed one small issue on my new Sig Scorpion 1911. I've been using all ball ammo, a few brands, federal, WWB, remington UMC, PMC, and Winchester SXZ or whatever. Issue has existed with all ammo i think. Also using 2 factory mags, and 2 wilson combat mags. The issue still appears with both, but i feel like its MORE with the facotry mags. 95% of it feeds just fine. But ever so often I get a round that refuses to go fully into battery without assistance. The slide cycles, ejects just fine, then it strips the new round and stops about 3/8" from going into battery. If i go to clear the malfunction with a "tap rack flip" the slide normally finishes seating as soon as I tap the mag. or i can reach up and nudge the slide with my thumb and it'll seat. I just dumped about 700 rounds through the thing at front sight, and this would happen every few magazines. totally randomly, but never twice in a row. I had no other malfunctions, no stovepipes no type 3's, so i doubt im limp wristing or have severe magazine issues or anything. Any idea what it could be? The first 3 days of the class the gun was stripped and cleaned a bit, wiped down the feed ramp and whatnot. The 4th day i didnt clean it, but that seemed to have no real bearing. I suppose its possible its just not lubed enough or it was getting grimy, I'll see how it reacts when i get some froglube on it, but still, i feel like it shouldnt be doing that as much as it is. suggestions on where to start?
