I fired the HK full size .45 and the Sig full size. Unffortunatley they don't have the compacts to shoot, even though they felt the best in my hand, and were easier for target acquisition. Which handgun do you like better? I hear great things about the sig & great things about the HK, is it a wash? I am most interested in reliabilty (since the gun probably shoots better than I do.) Thanks in advance for your input. N8.
