glockler,
The ejector cracked in such a way that the slide stuck. Neverending stovepipes. Overall, it was an unpleasant gun to shoot for it's size and caliber. My brother had the same problem when he had his PPK/S, too.
I'm going NUTS because I haven't been able to take the HK to the range yet. It's been whispering to me all night long - "shoot me.....you know you want to......." I did put Houge slip-on grips on it; I don't like frontstrap checkering.
In Para news, my brother LOVES it. He wants to trade. I told him he NEEDS to weld the recoil system better, because I wouldn't trust it as is. He's very good with tools, and he said he might actually make a new one. If the HK works out great, than I'll trade. Hmmm..... Trade for?
