I had one of the first 10 mm’s, like back in 93.
It was the middle of winter when I was going to test some loads (200 grain XTP). Colder than a bitch outside. Anyway the first shot was a click. I thought I forgot to chamber a round. I had doubled up on ear protection( plugs and muffs)., so I never heard anything suspicious.
Anyway I racked the slide and fired over a rest. At the shot, i though it recoiled a touch much. The target had an oblong hole in it. Turns out it was two bullet holes, one on top of the other.
After the snow pile had melted in the spring I found those two bullets, l kept them for years as reminder and conversation piece. So I had shot 400 grains out the barrel. The pistol was totally fine.
And you did not NOTICE it throwing an empty shell out???????
