your m1934 is fine with any off the shelf .380
Would Fiocchi .380 ACP (95 grain FMJ, muzzle energy 215 foot pounds, muzzle velocity 1010 feet per second) be too "hot" for a Model 1934?
np, the m1934 was built until the early 90s so any modern ammo is good to go
Be careful of after market magazines if your going to use anything other than FMJ ammo! My 3 WWII magazines will load and handle any brand of HP ammo I run thru it. But my two aftermarket units will NOT. I'm ordering Wolff 1934 springs and hope this will solve the problem.
