I am not real familiar with the H&K but it does not sound normal for any auto.

Is the Mag Loaded?
If so than maybe.
If not loaded than no.
Check to see how you load the mag are you hitting the slide release with your thumb when you slap the mag home?
In two weeks I will see My buddy Mike who is the Local H&K rep. I will ask him.

Yes it does it with the mag and loaded. My finger is clear of the release. Just wasn't sure if it would be an indicator that something else was wrong or it was normal? Thanks again

I think on the compacts it is normal.
The guess is you are reloading on an empty gun.
It has been a couple of years since I worked the booth and seem to remember the 2000 and the 2000K had that feature.
All the guns should stay locked open on an empty mag.

Many semi-autos do that when the magazine is slammed home hard. My 1911s do that, and I count on them doing that during a quick magazine change. When I insert the magazines without slamming them in hard, just hard enough to lock them in, I have to use the slide release to unlock the slide and have it go forward to chamber a round.

If you don't want it to do that then don't slam the mag in; if it is a bit unnerving then understand that it may be another positive function of the pistol that you have just discovered, in which case I would suggest you use it appropriately..............

yes it could be a positive feature if i wanted to skip the step of releasing the slide i just wanted to see if it was normal and it seems that it may be. i dont normally slam the mag in there but did it today for the first time and found out what happens, nice to know incase i need it. thanks for all the input.

This is not to start a flame--but--
I just went thru all my auto's and I could not make that happen
loaded mags or empty.
Maybe mine are different.

It's happened to me with Ruger, Glock and Sig. As an instructor I've seen it happen numerous times on the "line."

Two of those I tried this AM were Sigs.
I dunno---maybe I did something wrong.

Don't know about H&Ks but on Glocks the slide stop spring gets a little weak, then a vigorous mag insertion will cause the slide to drop. My Sig 220 and at least most of my 1911s do the same. It's great by me. When I insert a loaded mag I want the slide to close anyway. Like Mikey, I think that's a good thing. It shaves a few hundredths off my mag changes! I need all the help I can get. William, You have to put the mags in like you mean it!! LOL

Ya wanna see the pinch mark on the heel of my hand from this morning.
Maybe that is a sign I need too shoot more and wear them springs down.

William, that pinch mark tells me you need some bumper pads on the floor plate of those magazines! Plus-------ya gotta seat the mag like your life depends on it!!!

USPs are noted for closing on mag insertion, the newest ones do not because people complained and they changed the shape of the notch in the slide.

williamlayton · « **Reply #14 on:** February 04, 2010, 06:09:58 PM »

You boys got me all concerned now.

I am doin sumthin wrong

Could it be a mag issue ?
Where do I gets these self-closin mags ?
Really I dunno? I aint mad or happy--I just dunno

I didn't try a bunch of different mags-----I is so sorry boys, that mine don't do what it is their susposed too. Can we still be friends even tho I am/mine are different?
I guess this will have to be one of those don't ask, don't tell things.

William,
You don't have a terminal condition! Shucks, your condition doesn't even require therapy. Until I started shooting action pistol games, my slides stayed back until I hit the slide release!

Spoke with my buddy that was the H&K rep and he said NO not a feature.
He thinks you are hitting the slide release some how.
But the violance of your action to slam the mag home may ne jarring the slide somehow and with a full mag it allows the slide to go forward.
Not sure.

HAMMERHEAD · « **Reply #17 on:** February 27, 2010, 12:12:33 PM »

It's a well documented occurrence with USP pistols, and has been for many years. If an HK rep says it's not a designed feature, I believe it, but there's no way they don't know that it happens. It happened many times with my first couple USP pistols, it's been well discussed at the HK forums for at least five years, and the newer models have been changed to prevent it from happening.
It was the single greatest complaint against USP pistols, followed by overly sharp checkering, which has been changed as well.
