Wow interesting? I had 6 glocks over the years not to mention a lot of other striker fired pistols. Not sure if this helps, but I think glocks are well made, and they shoot well, It took me awhile to get onto them, I mean a thousand rounds to get to the point where I was hitting well, quite a adjustment. Now a sig 320 I hit well right off. Sig 320 is one of my top picks, but I like the Tp9sa, mine s the mod 2, and the trigger is nice, trigger reach really suites me, and it just works out of the holster for me. I am no expert but my pick would be the canik,then the sig 320, m and p 2.0 or beretta apx tied for 3rd, oh ya through in the fn509 for 3rd. But it is what you like that matters. And will there be parts or other after market stuff for the pistol? I never add sights or red dots or other enhancements to my pistols, I shoot them stock, but I do buy the odd recoil spring and holsters. Good luck, oh to be fair I have never shot anything in the hk line up. Glocks have lots of aftermarket out there, and are well proven. If I bought another and I probably will not, I would go for a gen 4 17 with a med backstrap, and call it a day.
