Before you refinish the gun I would have the cylinder checked. I had a 29-2 that leaded badly with cast bullets no matter if there was a gas check on them or not. A few years ago I read that many of those guns had oversize cylinder throats so the only real cure would to be have the cylinder replaced.

As to refinishing...for a hunting gun hard chrome would be hard to beat. My daily carry 1911 now has 8 years of daily carry and still looks like new. A matte blue or parkerizing would also make the gun nice looking but not so nice that you would not want to hunt with it.

I have a 57 8 3/8" that has a few little blood stains on it that I hunt with regularly...not going to worry about what it looks like when I am done...life is getting too short for that.
