HKs are beautiful machines. I have had many...having been previously spoiled by Glock's low bore axis and fast return to battery, the top heavy and slow feel of the HKs kept them from becoming a permanent fixture. They are very nice machines, though. I loved the appearance, feel and manipulation, even the trigger-finger actuated mag release...I just didn't like shooting them.
I tried Hk45 (twice) along with multiple USP45Tacticals, Compact Tacticals, etc. The CT is easily my favorite. Don't own any of them anymore, but I still like them.
