+1 for the Rock Island guns. Mine has been 100% reliable and is the most accurate autoloading pistol I own. I have some revolvers capable of showing it up, but not all.
I own one. Great pistol. It’s also heavy enough to use for weight lifting exercises when I’m not shooting it.Since you specified used, I don’t think you need to go to a super cheapie.
I found this Colt Series 70 for $700 less than a year ago.
The Norinco was $350, down from $399, a few months ago. It’s a great pistol, and it is good for generating some harrumphing with its Made In China pedigree.
Of course neither of these pistols are true 1911s, lacking a grip safety and other parts that may or may not be interchangeable with a 1911. Not my first choice for something that I would shoot and want to keep running and/or modifying.Redlevel, if you can pick up a surplus Argentine Ballester-Rigaud, or Ballester-Molina in good condition cheap in Georgia, they are very good .45 acp pistols. I remember when they were selling for ~$300; look them up on Gunbroker now. That will tell you something.The Argentinian magazines are usually worn out; so, replace them with new, good quality .45 acp mags. They fit. I'm thinking you may be able to pick one up cheap at an out of the way LGS, or Pawn Shop. Good luck with whatever you end up doing!
