That poor MP5!!!When I was with the training unit at my Sheriff's Office, we started transitioning everyone from .40 to 9mm. That meant having two pistol calibers on the range at the same time. ?
We would tell the class, and I am directly quoting here, " We have two different types of ammo out here. We will keep the 9mm on this side of the range and the .40 on the other side. Don't unload your 9mm into the 40 can. Don't unload your 40 into the 9mm can. If you do that, you will be creating a BIG BALL OF FUCK. Don't be the person who creates the BOG BALL FO FUCK."
Inevitably, one of us instructors would have to announce to the class something along the lines of, "Congratulations, class. Someone amongst you has created a BIG BALL OF FUCK! Now you get to sort all of the ammo before you go home."
It was funny how, collectively among the training staff, it was known as "THE BIG BALL OF FUCK." ?
I gotta say, I've seen a lot of 9mm fed through .40 Glocks while I was with the Sheriff's office, and I was impressed with the Glocks. Usually, we'd see a short stroked slide and a form-fired 9mm casing, but no stuck projectiles or exploded guns. Well, except one time, we did have a stuck project that led to a bulged barrel and a locked-up slide.
I can also attest that full-auto an H&K MP5 .40 DOES NOT LIKE 9MM.
Someone created a different kind of BIG BALL OF FUCK X2 with a can of 180 GR (sub-sonic) by emptying several mags of 165 GR .40 in it. The SWAT team couldn't use that ammo in their suppressed MP5s, so we grabbed the can of ammo, several mags, and two MP5s off our training rack to "get rid of the ammo." Wouldn't you know, a few 9mm rounds found their way into that can of ammo, too, and one got loaded in a mag (Sorry! I was BS'ing with my buddy!) and fed into the gun.
The gun short-stroked; I quickly and manually cycled the bolt and BANG! Two .40 went off (full auto) into a squibbed barrel.
It was an expensive fix, but I still have all of my parts. The MP5 had to be sent off to H&K to be re-barreled, and my boss was displeased.
