Back in the early 70's I shot some Bullseye, and one of the guys I shot with , used an old K-32 for the Center fire leg of the Match. It WAS surely quicker back on target than any of the .38's and especially those who used a .45 with wadcutter ammo. I REALLY fell in love with it.
Borrowed it and shot it a bit at home, that is where the romance ended. It required handloaded or factory ammo, which at the time was FAR tougher than the ubiquitous .38 wadcutter I used in my K38. Or the then super cheap .22 rf I shot out of my K-22. So I gave it back and short of a Bullseye gun, saw little use for it. IF I had access to free or cheap ammo, I probably would have bought one as it was super accurate with minimal recoil. Would have been a great ground squirrel gun!
Little did I know the K32/M-16 would become a collectors item. Then again , same for the M-520 and M-547's in the 1980's. Narrow focus guns, that didn't sell well. NOW they are rare and sought after.
In the late 70's a gun shop I frequented, found a pair of late run, probably 1973 or 74 guns, stashed in their safe unnoticed for years. I can remember like it was yesterday, those guns on the shelf, WITH a case of .32 wadcutter ammo, for $399 each.
