Old guns
Just remember to never fire a .32 ACP in the old top breaks. The old guns top out at around 9000 PSI while the .32 ACP is closer to 15,000 psi. A modern .32 can safely fire the acp. I have a 31-1 which I have fired the acp rounds through without a problem, except for the lower POI due to the lighter bullet.
