I inherited a Sterling Arms Mark II .380. I had it professionally cleaned and serviced, but the gun jams constantly. I'm assuming it might be an ammo problem. I've tried a couple different types of ammo, but to no avail. Any ideas?

Is it reliable with FMJ ammo? If it is, thgen use something like Hornady XTP, or Remington JHP, not the stubbier premium ammo.

I have a Sterling MkII Model 400S, and it's finicky about JHP ammo. You may also want to clean the magazine, and replace the magazine spring.:)
