with the exception of my SA XDm40, none of my other pistols have polished feed ramps. the XDm is the only one out all my pistols that even has anything that remotely looks like it's polished.Then why do brand new pistols including but not limited to 1911s come already polished? It runs smoother and is easier to clean.
all of my 1911's and all my pistols run plenty smooth and are not difficult to clean.
so have you come up with some type of scientific measurement that quantifies that one runs smoother and is easier to clean because it has a polished feed ramp? because if not, that's strictly an personal opinion and not a fact.
