Any arfcom LEO's here armorer-certified on the H&K USP? I have a quick question with reference to the USP45.
[for the record, my agency issues and carries Glock 22/23/27 and no we are not looking at switching] |

Quoted:
Can it fire without the firing pin spring installed? Wow, thats random... Im going to guess yes from what i remember of the of the firing pin channel and firing pin block which is kinda similar to the 80's series colts. Only thing is the firing pin might not retract and could get damaged by the next round to chamber maybe. But basically, i have no idea.... |

If you really NEED to know ( for a criminal investigation or something ) and you're willing to replace the pin of i kill it, i will take my spring out of my old duty USP .45 that i dont use anymore and try it while tape recording the results for you. I played a similar game for a guy a while back demonstrating why NOT to mussle strike a person with a 70's series colt. Caught some splinters in my face from plywood on that one. 
I guess my sig line should read, "intregity AND unusual firearms knowledge dont come cheap"

Also, the top end of them are short bus simple. Extractor and spring and roll pin, firing pin spring and pin, and and firing pin block and roll pin.
Its the fire control group on them thats stupid and overly complicated and nearly impossible to put back together. The little trigger return spring is the absolute friggin worst! |

I'm a field armorer for our P2000 and USPC. During the course, we spent about 2 days taking them down and putting them back together. Our test consisted of completely tearing them down and the instructor came over and mixed the parts and all the parts from the student next to us together. We then had to divide up the pieces and assemble a functioning pistol. To the OP, without testing it I would have to say maybe. The spring pushes the firing pin far enough back for the hammer to hit it. Without the spring, if the firing pin happen to be sitting far enough back to be hit by the hammer, it could fire. Maybe if the pistol was pointed up? This is something that would probably have to be answered by an advanced armorer or someone who had a USP F that could take the spring out and try it. |
