HK http://www.geocities.com/raydiationtemplar/43600044.JPG http://www.geocities.com/raydiationtemplar/43600038.JPG http://www.geocities.com/raydiationtemplar/43600042.JPG Anyhow this is my second pistol, my only other one that I have fired was my Colt 1911 Single Action. This is my first double action pistol. Was kind of nervous with the decocker hitting so hard, gotta get use to it and trust it. Seemed kind of light to me though it would be heavier and larger, but thats probably because I was comparing it to my friends .44 Mag Desert Eagle. Going to the range tomorrow to break it in. |

The decocker doesn't hit hard. It's basically just the hammer going to stop. The decocker on late model USPs can be trusted. It allows the hammer to sit away from and never contact the firing pin. Even if it did, the firing pin block would not allow the firing pin to go foward and hit the primer (lowered only as trigger is fully to rear). It's a safe system. Enjoy. As it's more top heavy, you will notice a bit more muzzle flip than a 1911, but it's still a good shooter. Of course...no need for ball ammo either now...

I have an early model USP (1993). Do they use a different decoking system? |
|
Yes, at first the decocker dropped the hammer all the way down (no half-cock notch on the hammer) and it was up to the firing pin block to keep the gun from firing, and there were a few cases where the FPB DID fail and the guns went off when being decocked (see, always a need to keep the gun pointed in a safe direction). The old system also had a hammer rebound spring IIRC to move the hammer back off the firing pin after decocking so the FPB could disengage easily when pulling the trigger. Then HK went to the half cock notch and did away with the rebound spring since it was no longer needed to keep the hammer from resting on the firing pin. Now when you drop the hammer the hammer drops to the half cock notch so in order for the to go off accidently both the half cock notch and firing pin block would have to fail. |
+1 Correct Wait, your never wrong because your the one who has practically written a book on HKs. lol

That's a helpful information about the decocking mechasim that might fail when I decock the USP... thanks for a helpful information, I will be more caution when to decock, I have decocked on live ammo and it has never went off, (I have done maybe 10 times that is when i am at shooting range). But never know hen I will post more pic of my USP in photo thread Cheer |
I'm with you on this one. Never a problem with my HK either. That said, I never "trust" my decocker regardless of manufacturer. Any mechanism which has the hammer moving forward toward the firing pin with a round in the chamber is an accident waiting to happen in influencing how I handle the firearm. Be sure to aim the handgun in as safe a direction as possible before decocking it. |
| I had to go with this one because the Tactical was out of stock and Impact guns charges 150 dollars on orders over $1000 if I canceled. So I was sort of forced into getting something else. Anyhow I am still happy with this one as I have tried the decocker several times and have now learned to trust it. Although I need to practice alot more as I discovered a violent flinching action I have when I was trying to fire it DA anticipating the recoil. Practice makes perfect. |
Here's a simple solution to both problems: Don't decock! Cocked, locked, and ready to rock. |
This man knows what hes talking about. Cocked and locked= one of the best features of the USP series. |

U know, it does affect me to Manually Decock, by pressing the trigger and holding the hammer to put down in forward position. I never manually decock the hammer while it's being loaded. would it go off if i manually decock? I dont believe so because the hammer has to strike the firing pin hard to order to fire the ammo in the chamber. |
When you manually decock, you disable the internal safeties in the gun (firing pin block, half cock notch) that would prevent it from firing. Use the decocker if you want to decock. Mine are variant 9, and the few times I want to decock I do so very carefully, to say the least. |
It's better to decock it by using the decocker than by pulling the trigger and letting the hammer down, if that's what you're asking. I was just stating that you could forego the whole procedure. |

The info that have is that they changed the trigger mechanism in 1995. The info does not say specifically that the hammer was changed but the reasons for the changes to the trigger mechanism are listed as "Improve drop protection, reduce manufacturing costs, eliminate hammer over travel." I have only heard of the rebounding hammer on the very early pistols, such as the 93 and 94 pistols, so that corresponds to the info I have about the changes made to the trigger mechanism. When it comes to decocking ANY USP, if it has a decocker, use it. Remember, the failure of the FPB to keep the gun from firing during decocking was VERY rare, but if the FPB spring broke or the plunger froze in the up position, it COULD fire when decocking. COULD, not WOULD. If you do not have a deocoker, such as a V9, be very, very, careful. One slip and she is off and running. |
| My wife had a Sig 239 and the decocker was nice and controlled. She bought an HK compact and the first time I hit the decocker I thought damn that doesn't seem safe. After watching the release a few times you can see that it's safe but the sig makes you feel like your more in control. However the HK is by far a better shooter and more accurate gun. |

One of my buddies has always had a grudge against HK handguns. I always figured it was for an unjustified reason, but I recently found out that he had one of the early "secondary trigger" decocking USP's. He got extremely lucky. Not thinking there was any worry, he decocked his pistol while aiming it to his left side. The gun fired and the round hit the wall. No harm, no foul, but if he was in any of the other lanes, it could have been a pretty major AD. I'm going to have to send him a link to this page as he liked the pistol but sold it because of those events. |
NEVER manually decock any pistol. The decocker is there for a reason and the chances of your thumb slipping and having a negligent discharge are too high. Take care and shoot safe, Mike |
The HK45 will probably be an improvement in terms of size. I agree that the USP45 is a bit big. |
Yep sure looks purdy, first version one W/out finger grooves. Hope they go with that design frame. I also like the idea of interchangeable backstraps, cuz I have medium to smaller sized hands. My full size USP is just a tad thick in the grip for my like'n, but at the time was one of the thinnest DS 45acp out there. From the reviews I've read the grip width is the same as a 1911. Will probably trade in my USP for the HK45 or if funds permit buy one and keep both
