I think the Handi Pistol would be great, all matters of likelihood and liability aside. I can imagine the synthetic rifle stock (without the Monte Carlo) with the butt cut off behind the pistol grip, and it looks sweet. Cartridges like 22 Hornet, 204, 223, 22LR, 22WMR, 17HMR would be perfect.
But on the other hand, this thread made me wonder about Savage and the Stryker bolt action pistol that was discontinued after a very short life. Could liability or regulatory problems have been issues there ?
