Personally, H&K is one brand that is worth coughing up a little extra dough for.
Now, "how much would I pay for a new H&K45?"
Depends on how much I'm making. :P
As of now, I would hate to spend more than $1300 on a handgun.
But H&K is one of the few brands that is worth the $$$ in my opinion.
They make freaking grenade launchers, cmon.
