At the range with my HK45 and HK45c. Had this happen a twice with the full size. What causes this and can I fix it?

Weak mag springs is often the cause.

Check your grip. If your thumbs are close to the slide or even ride the slide during firing then you will disengage the slide release.

Keep count as you fire and on the last round fire it one handed. Betcha $20 it stays locked back.

You'll just have to live with it or modify your grip. My buddy had the same issue with his P30.

You know, I wonder how that's possible on the USP. I have big hands and despite that, I still need to reach up with my left hand to flick the slide catch on my USPf-9 after a mag change. My right thumb doesn't quite reach comfortably.

This. Same here with my P30, although never an issue with my USPf's, but occasionally with my USPc's

+1 on weak mag springs...do you leave your mags loaded constantly or rotate?

 

[BoppaBear]

+1 on riding the slide with thumbs...doesn't take much contact/pressure to keep the slide from locking.

Shoot the same ammo thru the same magazines using a one hand grip. This will eliminate touching the slide stop with your support hand. (Close the slide by cycling it if two hands are available.)

Thanks for the replys. I'll give them a try at the range if it will stop raining! I do leave my mags loaded but I go to the range at least two or three times a month. Unload my personal defense ammo and load my reloads for the range. Maybe I'll load one less round between range trips.

Another vote for riding or contact with the slide release.

 

[darkknight]

Yup, that happened to me too. Riding the slide

 

[Apollo11]

If the slide will lock back with an empty mag when hand cycled it is more than likely NOT the mag springs. You're riding that slide release lever mang, adjust your grip or don't run the gun dry.

 

[azimuth]

Tuck thumbs. Rock and roll.

+1 Riding the slide release was the culprit when I've experienced these issues.

As others have mentioned, it could be one of a couple of things.

First, your grip may be causing the slide stop to be depressed down during the firing cycle.

Second, weak magazine springs could cause the magazine follower to not be pushed up enough into the slide stop.

Third, weak ammunition could cause the slide not to be going back far enough - or if the gun is new, the tight springs might be contributing to this (strong springs plus weaker target ammo).

Fourth, the gun just doesn't like you. Send it to me and I'll take care of it, no charge.

Option 4 sounds good
