There are some inexpensive single shots,,,
Rossi makes this one that's actually quite accurate.
Matched Pair Pistol .22 LR and .45 Colt
I've looked at them for quite a while now,,,
One of my range acquaintances bought one early this year.
The .22 barrel is a very nice shooter,,,
The trigger seemed a bit stiff,,,
But it's a new gun after all.
I hit a 1 quart milk jug at 50 yards with the .45 barrel,,,
I was resting the gun on a range bag though,,,
But I still thought it was a good shot.
