As a general rule, I refuse to buy a used alloy framed 1911 unless I know who owned the pistol and who did the work (if any). I have seen too many ruined by less-than-competent gunsmithing. In this case, the pistol has an alloy frame that has been cut, both for the serrations and the high cut front strap. It may also have been modified to fit the grip safety. This means the protective anodized coating has been compromised. If the frame has not been properly refinished, it could easily be damaged due to the soft alloy.
I would also take a good look at the feed ramp and barrel. If someone has messed with the feed ramp "to make it feed", it could be an expensive fix. The usual fix is to fit a steel insert into the feed ramp. George Smith at EGW does this fix really well.
If possible, I would shoot this pistol before purchasing it. This would allow you to check the function of the pistol and its new parts. I would run at least a few boxes of 230-grain Remington Golden Saber through it. If these feed, the gun functions, and the feed ramp does not get gouged, I would feel much more comfortable about the purchase.
