I've read several posts recently where HK45s were delivered new in the case without O rings and other issues. I've owned mine for about 2 months; it was delivered 2 days after I ordered it with the extra O rings and no visible or mechanical defects. My date code is BB and the test rounds were fired in June 2011. Maybe the date the HK45 was manufactured is an issue? Well, I hope the new owners get the issues resolved so they can have confidence in their new HK. I'm also new to HK, but not to firearms.....no matter what name is on the weapon, confidence for me comes with reliability and consistency. I have that in my HK45......after a few range trips and firing all types of ammo.
