Looking for some advice......the 229 is jamming (intermittently) when attempting to chamber a round. This happens when firing the weapon or manual reload. I have field stripped the weapon and found a few small "burrs" on the ramp to the barrel. I de-burred the ramp & polished with Micro pad slick as a baby's butt. I found no other excessive wear in the barrel action. I did "stretch" the recoil spring a tad....no joy. Help please......KK
