    reloaded my HK USP, and when setting the decocker the handgun discharged. Only because I was practicing proper procudures in pointing the muzzle in a safe direction was any major damage or injury/death avoided.

    Sucker goes to HK tomorrow for them to look at - I'm really upset as Im a stickler for safety and handling, and then this happens.

    I love how this is the end of the world because some jackass had his finger on the trigger when he decocked.

    If it's true, that's an actual AD.

    Not just an embarassed ND.

    I don't use the decocker on my USP. I'm also planning on getting the V.9 detent plate to remove that function so I can grip the gun more solidly with my thumb over the safety without worrying about it decocking at an inopportune moment.

    :h5: I think it's almost impossible for a SIG to do that, as you have to move your thumb back off the decock lever before it lowers all the way.

    I bet WAY more nd's have been caused by people that don't thumb the hammer down well than decockers. I sure wouldn't try anything but the dococker on a sig for example.

    There's also a known issue if you do your own trigger conversion on a certain model of USP. Something about needing a shorter hammer because it hits the decocker too hard with the original hammer. Though this would be the first actual decocker discharge I've ever heard of on a USP.

    Do the HK's have any sort of firing pin disconnect like Sigs and Berettas (and damn near every other semi-auto pistol)?

    It would be damned hard to do without multiple failures in the weapon. The decocker pulls the hammer forward slowly so there is little force (it doesn't just fall like on a beretta), the hammer cannot contact the firing pin (it won't travel all the way forward if the trigger is not pulled) and there is a firing pin block safety that locks the firing pin preventing it from moving forward unless the trigger is pulled.

    Yeah that's a bunch of BS. As EvilSS said, the gun would have to be REALLY broken for that to happen. Sig has even said NOT to manually lower the hammer on their guns because it can be dangerous. The decocker is completely safe.

    The DAK may be fine for you, but I can handle a DA/SA and prefer it.

    I'm not real familiar with safety systems, but I don't see anything about a firing pin disconnect in the USP manual.

    Oh, and that's from the Mark23, which I thought had the same safety system.

    The HK has 2 safties that I know of between the decocker and the firing pin. The first is a metal bar that prevents the hammer from hitting the pin, the second is a notch halfway down the pin that needs to be disengaged for the pin to move forward and hit the round.

    Both would have to either been broken or removed for the ND to occur... or his finger pulled the trigger, bypassing the safties.

    I hope the safties weren't broken :noes:

    I'm betting he either tampered with his gun (playing gunsmith) or he pulled the trigger while decocking.
