I know it's not the most creative topic and I know this is an HK forum, but in .45, HK VS SIG. Gimme the pros and cons. The Sig p220 is an incredible gun - I've never shot a USP .45 but I find it hard to believe that it couldbe better. Then again, Hk's higher-up variables like the tactica and the Mark 23 are beyond anything that Sig offers. The Sig p220 combat is kindof lame - same gun, different finish - no real upgrades. Thoughts?
