hoser,
The pros are that the Rem 32 was well made for target shooting and had good weight/balance for the job. The cons mainly are that it's an old gun and parts are either not available or have to be made or modified from Krieghoff parts.
As an old semi-collectable, moderate/light volume shooter, I think they're great. As a serious, high volume target shooter, I'd pick a current production, K-gun, P-gun, or B-gun.
BTW, the Krieghoff 32 is the resurection of the Remington 32 after Krieghoff purchased the design rights from Rem. The K-80 is the renamed version that was slightly upgraded around 30 yrs ago. The one K-80 I owned never missed a beat in the few yrs I had it. The only negative to me was that it was slightly heavier than I would call "ideal" for me. I had a 28" skeet gun and it was too heavy with a 32" barrel for me, so I sold it and bought a 1/2 lb lighter gun with a longer barrel for my sporting clays shooting.
