Brian:
I'm new to FL, but I've had feeding broblems with my V-10 Ultra Compact as well. A ramped/throated barrel didn't help, then a second smith told me the rounds were catching on the frame cut below the feed ramp, and that smoothing this would work. He showed me empty cases actually being damaged at this point. Extractor tension seems OK. Have you encountered this, any thoughts?

Ross,
The nicks on the feedramp can cause problems. I'll try to give you a brief idea what the problem may be.
Round stops dead on frame feedramp- Could be rough/nicked feedramp, improperly cut feedramp on ramped barrel or weak magazine springs.
Round goes up feedramp but stops with arse-end still in mag or downward- extractor tension too tight or extractor not radiused and tuned right, breechface walls too tight or crooked, rough breechface or sharp edge on chamber not broken allowing the round to rollover.
Round feeds into chamber buts sticks out of battery- Chamber too tight or not enough leade into the rifling, causing the bullet to stick into the rifling.
As far as the slide stop goes, it could be that the tab on the insdie of the slide stop is too long and rounds are bumping it. Look to see if you see brass marks on it. On all of the combat guns I build, I detent the slide stops to prevent this.
Another thing, if the gun is stainless, make sure to lube it with the proper kind of lube in the right areas. use a red lithium or stainless grease, not oil. Also Dextron Mercon II synthetic trans fluid is a good lube. Lube the inside of the slide in the barrel channel and the end of the barrel where the bushing rides, then lube the rails. If a stainless gun isn't properly lubed it will gall and bind/pick up and that will cause malfunctions.
