[44mag]

i have a limited budget (about $600), and i am looking for the perfect gun.

what i want is a .45 semiauto, no bigger than commander size ( i am short and have small hands), that is either single action or something along the lines of the para light double action. i really don't like the double action pull of the first shot, plus i simply can't hit anything double action, while i do fairly well shooting single action.

i saw a rock island armory commander for $370, but at the time i had never heard of rock island, and had no idea what kind of quality they are.
i had a ruger 345, which i really liked except for 2 things; the double action pull of the first shot, and the fact that my support hand thumb kept hitting the magazine release button (not a good thing).

what do y'all suggest? am i limited strictly to single-action guns, or are there others out there available similar to the light double action of para-ordnance? what brands are pretty good quality, but affordable? i do reload, but i'm a beginner, so i need something that willl digest alot of different ammo out of the box.

any suggestions?
