Matching Colt New Frontier, 686's in different length barrels, many N,K&J frames in different barrels and calibers. 1-19, 2-23, 2-22 glocks, couple kel Tec's in 9mm & 380, many 1911's Colt, Kimber, Springfield, Para, couple Berettas, couple Ruger MKI's.
Only intentional match up was the New Frontier's one I've had since I was 10 the other I found in real good shape and picked up so I could give one to each of my boys. I guess they will end up with more than a couple 22's.
