I bought a Beretta 8000 in 9mm para nib from a individual recently. It also came with some niw hi-caps. I just noticed that the hi-caps are marked (Beretta 9x21) rather than (9mm para) like the original 10 rounders. Will they work ok?
It should be fine, AFAIK. The 9 x 21 has a longer case, but the COL is the same within a couple of thousandths and the case heads and diameters are the same. The two extra thousandths of COL in the 9 x 21 are meaningless in the context of magazines.
