I have an old german ortgies 7.65mm pistol that I love to shoot at the range. It is a fun pocket gun and very accurate. It says 7.65mm but everything I read says that it is the same as .32 acp. It fires the .32 fine but the ejected shells sometimes jam on their way out the slide window. I can't find any plain 7.65 ammo from overseas and most of that ammo is still listed as both 7.65 & .32acp? Is there really any difference in those bullets or is something wrong with the gun? Would extra deep cleaning help? Anyone have any experience in this? Thanks.
