The fact that you 'put it together' out of various parts makes it very suspicious as far as parts fitting and function/reliability are concerned. Now if you really are a gunsmith or armorer and were just being coy about fitting up this pistol, that's a different story. Generally speaking, many 1911 fanciers love a rebuild or match build based on a M1911 frame - there's just something about it that seems 'right' - but those grips negate all that. Grips that usually would be expected to appear on such a pistol would be pre-war Colt fully-checkered walnut (28 lines between screw holes) or any WWII brown plastic grips. Did you blast and Parkerize the frame and slide? Looks pretty good. The frame had some pitting and had obviously been refinished before judging by the soft edges and 'dishing'. But, as a shooter, it should be great because the slide is one of the fully-hardened ones that are tough as nails.
Just noticed an old Augusta Arsenal 'AA' rebuild mark on the frame so that was definitely one of the refinishes. You would be hard-pressed to get more than $500 for it normally but if you put it on Gunbroker you may be surprised what it could bring - they go nuts sometimes.
