Well, a week after getting my new HK45 and putting 800 rounds through it I can say that I am thoroughly in love with this gun. I have never shot another semi-auto pistol that "just works". It's great. Now all I have to do is learn to get my groupings up. I'm still shooting about 2" low everytime. But it's a vast improvement over the first day. I know the HK uses the cover hold sight picture and that's what I have been doing but for some reason (and I think I know what it is, limpwristing before trigger pull) I'm still low. Oh well, back to the range next weekend and more practice, practice, practice.
