To jimjc ... sorry about the sidetrack.
If you do a search, or just read backwards in the 1911 forum, you'll find multiple threads in the last several months about the wisdom of 'building up', 'modding out', or just plain customizing 1911's. Of course you can do what you want .... its YOUR gun. However, many new 1911 owners (not that you are one) get their first 1911, and a Brownells 1911 catalog, and before they know it ... in $50 and $60 dribs and drabs, found that they had now have $1000 ..... in their $600 1911. Not only that .... it doesn't work anymore.
I've been shooting, and collecting 1911's for 25+ years, and was trying to keep you from making mistakes that I've seen many many times in the 1911 world, some of which I've made myself. Working on and tinkering with a 1911 until it doesn't work anymore, or finding out after dumping what they thought would be a 'few bucks' into their gun, that they could have had a much better gun, had they just spent all the money they now have into their $600 gun, in the first place.
You can take any advice given here ... or leave it. As I said ... its YOUR gun. The amount of members who have sent me PMs thanking me for my comments FAR outweighs the snipers who seem to follow my posts with such glee, hoping to find something else to pick at.
Great luck with whatever you decide to do with your gun. As I said originally .... the SR is a great gun, but I don't care for the two tone look either, which I've made no secret of.
One thing you might want to consider, is having the black parts cerakoted to 'match' the stainless. They won't really be stainless, but they'll look pretty close. There's an ad in the classifieds right now with holiday special prices from a company that does great work. Link below, FYI.
