CZ-52, the original hand-cannon ...
I have to wear a baseball glove to shoot it. I am unwilling to attempt any of the trigger slap fixes out there. It was enough of a DIY project already.
My brother has an AIA Mini-mag III in .30 Carbine. Stainless steel, 6-inch barrel. That thing is a real hand-cannon. 30 Carbine is light for a rifle, but hefty for a pistol. Quite loud.
It’s so heavy and long that there is minimal recoil. The 6-inch barrel moves the noise far away from your ears. You aim it by pointing your trigger finger at the target, and only use the sights for fine tuning. Very natural aiming, and quite accurate.
Unfortunately, it went out of production many years ago, and there are almost no spare parts available. The firing pin on the thing broke a few years ago, and a gunsmith had to make a new one.
That’s why I like my Romanian TTC. It’s loud but accurate. Fits the hand surprisingly well. Tip ‘o the hat to our esteemed Travis McGee for his advice.
