So at a lower price point the RIA might be an option.
My thoughts, too when the title of the thread is "Which 1911 9mm would you choose?" So I was going to recommend the RIA, which Is the one I actually bought. And really like.
But then I read the first post, and the OP only wants to have an all-american 1911 that shoots the cartridge developed by Germans and most commonly associated with people who were shooting at Americans with Lugers.
-So my Springfield Mil-Spec 1911 is my favorite 1911, but wouldn't buy another one until they get their politics straight.
-My Kimber was a good gun, but the brush-off they gave me when I tried to fix a factory defective sight after the 1 year mark means I sold it and won't ever own another Kimber. Their warranty is short and they have 0 tolerance for people who have owned a pistol more than 12 months bothering them.
-Remington, no good, I have too many lemons that say "Remington" on them. Used to be a big fan, but not anymore.
-Of your choices, Ruger to me is the clear choice. Great company, no experience with their 1911 line.
But whatever you buy, get a compact (Officer's). The balance makes for a near-perfect 9mm 1911.
But if you decide to open up your choices some, get the RIA 1911 9mm compact. The only things on it I would change are the Beavertail and skeleton hammer. I just like old school grip safeties and hammers better.
