I believe it. The shooting range was the one thing I looked forward to when I was in boot camp. The Navy recruit handbook said we'd be firing an M9 Baretta (I think it was M9 Baretta, I could be mistaken) and a shotgun whose make and model I forgot.
Just watch out for that teacup grip.
What's the teacup grip?
It's a type of grip thats used when shooting pistols. The idea is to keep your nondominant hand underneath the magazine as some kind of support , instead of two hands locked together and overlapping around the grip frame of the gun .
The problem with a teacup grip used in conjunction with a semi automatic pistol , is that when there is an accident involving the improper discharge of a round, the magazine can be blown downwards out of the pistol injuring the supporting hand underneath it.
This can be seen with Glock pistols online. In those cases, in adequate chamber support results in case over expansion which allows the round to basically explode in the barrel. the resulting gases and explosion of which blow the magazine downwards and out of the pistol and can damage the slide and crack the frame. Sometimes, all it takes is a factory or reloaded round that has been double charged, which means it has accidentally been given too much Powder in the casing.
Basically what it all comes down to, is don't put your hand underneath the magazine. Just like you wouldn't put your hand in front of the barrel and pull the trigger. If something goes wrong, and that magazines comes flying down out of the gun , you don't want your hand there.
In the same token, never put your hand or any part of your hand near the cylinder of a revolver. There is a small gap the bulle must pass through between the front of the cylinder and the start of the barrel in front of it. Within the small space hot gases and flame escape during the firing of the round. If your hand is anywhere near it , it's going to blow your finger off like a hot dog .
