Hope I didn't come across rude. Not a lot have gotten to play with some of the H&K classic arms. Really well built and engineered. My last H&K purchase was a while ago when I picked up a MK23. Not a fan of the newer offering in pistols or rifles to the civilian market. Add to that the big hit they got from their own courts when they were busted violating German law by selling to Mexico.
Big issues at H&K. None of em good.
I shot 12K+ rounds with my HK45 before the flat spring broke. Everything from mild hand loads to HOT DoubleTapp +P Ammo. Still one of my faves, but no reason for me to spend those dollars when I can get a reliable Glock, etc. for a lot less.
P.S. Only malfunction was from a round of Wally's WWB ammo with an oversized case
