I have owned two 10mm's in my time. I think one was the 1076 and the other was 1026. Many years ago the Virginia state police dumped a bunch of guns. I got one of each of the above for $300 and it include 3 mags and police leather.
Both guns were a handful, but were very accurate. The only reason I traded them off was the price of ammo. I now reload and wish I would have kept one of them. They were brutal on milk jugs filled with water.
From what I have read on the Glock 10mm's I wouldn't mind picking up one if I found a deal.
