I have a newer full size rock island armory 1911. Has adjustable rear sight firmer optic front sight. Stainless guide rod. This isn't just the baseline ria 1911. Shot it this Saturday and it was flawless. I put literally 36 rounds through it. Very accurate very smooth with no hiccups. Cleaned and oiled it. Lookin for cash. No trades. Excellent gun! $600 obo. Located in portland.
