If the timing's good and it's locking up fine, there's really nothing that could go too wrong. The particular notch locks up with the cylinder stop, correct? Check that carefully for binding or anything like that, as it looks like the concrete did a little custom stippling for you, and it may have carried to the edges of the notch. If everything's in the clear, test fire it with some specials, and I'd think it would be fine. If it were mine, I wouldn't hesitate to try it out as is, provided nothing bent, etc.
That being said, it's your gun, and I make no claims of the condition of the firearm, as I cannot handle it in person, etc. etc.
