Try some different ammo types, and try different magazines. Those are the easiest culprits to run down. More dramatically - if trying different mags and ammo doesn't work - the barrel could need some ramping and contouring, the chamber might be too tight, etc. Will also delicately raise the possibility that the heavier springs for the 10mm may be making your pistol more sensitive to limp wristing. I have a half-dozen 1911s - full size, commander, .45, 10mm, vintage and new ... All have been flawless and not finicky at all, straight out of the box - with the only exception being a Springfield 1911 that was pre-owned (the prior owner tried to tune his 1911, but did a poor job - Springfield customer service was happy to fix it, even though the issue had nothing to do with them). All of them have fed pretty much any ammo I've given them, and have had no issues with factory, Wilson, CMC or MecGar mags. My 10mm is a Colt Delta Elite, and it just purrs like a kitten ... with a kick.
