In a revolver, you could get away with it. In a semi, no way. I wouldn't do it.
For MOST revolvers- no. MOST semi auto rounds are rimless, and most revolver rounds are rimmed. There can also be a difference in energy- .32 auto is much hotter than .32 S&W ammo. HOWEVER- there ARE revolvers that were made to use an auto pistol cartridge, such as 9mm Parabellum. There were reports of problems, not highly popular. Some, such as the .45 Colt revolver could be adapted to .45 ACP ammo using a "moon clip" that held 3 of the rimless cartridges. So it really depends on WHICH revolver and WHICH cartridge.
Any revolver. As for semi auto pistols, the 'Ring of Fire' guns (Lorcin, Raven, Jennings, Bryco, Jiminez, etc.) are designed to use cheap ammo. The Ruger pistols are pretty tolerant as far as ammo goes, as well.
NO
38 caliber revolver ammo
No
no
Some studies indicate the repeated use (20,000) of steel cased ammo will prematurely wear the barrel on semi auto rifles. The normal user will not see the difference.
No. The S&W .32 long is a RIMMED revolver cartridge. Your SACM is an auto pistol, and uses rimless ammo. See the link blow- it includes a pic of the cartridge. Sorry. PS- MOST rimless ammo headspaces on the MOUTH of the cartridge case. Where a revolver can shoot different length cartridges, the auto pistols are pretty well tied to the exact length cartridge.
NO! The .32 ACP is loaded to much higher energies than the .32 S&W Revolver cartridge, and cannot be safely fired in a revolver- especially one that old. You will also have problems extracting the fired cartridge case.
All weapons exhibit a preference for one or more maker/load. You will have to shoot as many as you can find to know.
use 32-20 ammo The caliber of the ammo is 32-20. It is not common although it is still available.
