You have to determine what you're looking to do with this gun or guns. One gun won't fit every event. I'm not on a tight budget, but I'll give you an Idea of what I have and use them for.
1. Kimber TLE - pretty much does any job, my first 'real quality' 1911, I use it for steel challenge mostly and fun target shooting. With a trigger job and ambi safety I'd say she cost me about $1k
2. SA Mil Spec - build into NRA Hard ball gun, its a great gun for target, but huge adjustable sights suck for any kind of holster draw, so it's just a target pistol only, that is her only purpose in life. I have some Gun Smith Fee's into her, but my total investment is a shocking $758, I've gotten some great deals.
3. SA Mil Spec Champion - CCW, concealable, horrible recoil. I've modified this little bugger, to be a true pimp gun, have about $800 into it.
4. Beretta 92FS - have to practice that DA/SA trigger, great all around gun, use it for practice and training, steel challenge, would love to do IDPA with it. She cost me around $612 + a 22lr conversion kit @ $400, been rebuild once, I use my issued mags in it. I drag this thing every were, steel challenge, target shooting, under the seat of the car, ect.
I'm looking for a 9mm 1911, can't decide, between a Kimber or SA; I've gotten into steel challenge and would like to get into more IDPA events, would like the reduced recoil and cheaper rounds that the 9mm provides, so that would bring me back to 4 1911's, cause that shelf in the safe is a little empty.
I'd get 2 SA Loaded models, in .45 and in 9mm if I could only spend $1800. That way I'd have 2 matching guns, for different purposes.
Now if you're thinking $1800 total; Remmy 870 $350, SA Mil-Spec $600, Savage 30.06 $450 and a little left over for slings, mags, holsters and ammo. That covers all the bases
