mallard,I was recently able to pick up this pistol and the slide does not match the frame. Would it be worth it to try and find a US&S slide? If so, where would be a good resource to look for one? Can anyone help point me in the right direction? Thanks!
Yes,...Nice find ! (And, Nice Pictures !!)
As you may know, there are three different US&S slides. It looks like you need a No "P" Slide.
Also, (along with what dsk mentioned) looks like you need a Barrel ("HS") and a Slide Stop. Show us the detail (checkering on your Hammer and Mainspring Housing) for further verification.
