Granted I know they're blowback but oy, the .45 HP is the same size as my 1911. I'm a .45 guy and am in the market for a CCW but size and budget is making go towards the 9mm and the C9. Seems to be a good pistol and enough people have died from 9mm that I'm not worried about it somehow being an under performer. However a compact version of the .45 would be great. Maybe even just a shorter barrel and get rid of the damn ugly extension on the bottom of the mag. Something along the lines of C9 size but firing .45.
