Okay, this is the deal: Kimber 1911 Warrior, (My wife got it for me

) and it will occasionally not feed the round into the chamber. It gets hung up on the feed ramp. I have read some conflicting articles about how you should/shouldn't polish the ramp and the throat (I think that is what it is called, the part below the feed ramp)
Before you even say anything about gunsmithing and polishing steel, I have polished every type of non-hazardous metal known to man and have the proper tools to do this without doing any damage. If I tap the magazine bottom it will put the round up and the slide will move it forward and into the chamber, that is why I think it is getting hung on the ramp. I don't want this to fail me at a critical moment and me be stuck without a working pistol.

That would suck.
Nevertheless, I was thinking of polishing it and wanted to get some opinions. Does it improve the feed?
The only rounds I have put in the gun are Magtech 230gr FMC 45ACP, it seems like okay ammo, but kind of cheap looking compared to the hand loads that my dad uses. your thoughts? Thanks in advance
