Sounds like a good buy. Take the grips off an check for wear under the grips. Put something else back on.
I put Pachmayr grips on my Colt Government when I first bought it. Many thousands of rounds later, I replaced them with some nice wood grips.......and noticed that the Pachmayrs had caused wear on the otherwise pristine blueing. Several places were bare metal. You couldn't see it with the grips on and I'm positive these wear marks were not there when I put the grips on. Probably has something to do with the metal inserts Pachmayr uses in the grips. I was a noobie back then so it's possible that the grips loosened under recoil and this was caused by moving around but I can't recall ever having grips on this particular gun come loose. Anyhow, if it's going to be a safe queen find out what the original factory stocks were and get a pair. Probably walnut with the Colt seal (my Government came with these and I recently put them on my 1991A1).
