I'm in the exact same boat as you. I've wanted a 1911 for a long time now, but it is not as practical as the guns I have bought more recently. Now the Wife and I are done buying any guns or gun related stuff (minus ammo) for probably a couple years. Our oldest son needs braces real bad
When I do get a 1911 I am probably going to break from the norm and get it in 9mm. I don't have anything in 45acp and I don't think I really want to add another caliber. Plus, the Wife is pretty much totally against adding any other calibers to our collection.
Good luck saving and have fun researching. Sometimes for me, researching is pretty fun.
