Hk p2000sk problem

[Doubletapp]

I bought an HK P2000sk back in August as a cc gun. Although I love how the gun shoots, every time I fire the last round the slide does not stay open. I have about 500 rounds through the gun so far. This has never happened to me with any other firearm. I have about 2000 rounds through my sig 229 and not once has this happened. Do you think it's just my grip on a smaller framed handgun or could it be the magazines? Has anyone else had this problem with this handgun?
Thanks

Shoot it one handed. If it doesn't happen then, it's your grip.

Nearly 100% certain that it's your grip. Somewhat common on HK's. I had to adjust my grip as well. All is well now.

A friend of mine experiences the same thing on his XDS, check to see if you are unintentionally holding down the slide release. I bet this is the cause.
