"A photo of a KB'd pistol is seldom a condemnation of the pistol, but one of profound ammo error."
I don't honestly think that's even a kaboom. I don't think anything short of RDX in a 9mm case could take a steel frame (and slide) apart like that. I posted it because it came up in my search results and I was 'amazed.'
I figured others would be, too, and might know the story behind it. My money's on grenade-induced demill, but it's hard to tell.
"As for the trigger, you just need to shoot one"
Yeah, I keep hearing that, and I keep
not seeing them for sale at the local gun shop
. I'm not contradicting anyone with experience; just saying that the vast majority of fans/haters/unaligned's have to take every description of the gun's performance on pure faith due to its scarcity. It's simply asking too much to suggest someone 'just go shoot one' (sorta like the joke about "I can't
tell you how great
Lost is, you'll just have to watch all 200+ hours yourself"
). My point was that in examining the inner workings of the trigger group, the design didn't look particularly optimized for short takeup, low overtravel, short reset, stiff break, or even light weight --features we typically use to describe quality triggers. It looked more like a decent-quality standard striker setup with a unique/clever cocking system; functional, but nothing to write home about as far as the trigger.
Which is why I postulated that the 10-12lb grip on the safety may be fooling shooters into thinking the trigger is lighter than it is by way of sympathetic motor responses in their fingers. Gripping the cocker preloads their trigger fingers more than consciously intended as they pull the trigger back. More smoothly, too, with fewer muscles shaking as they pull in opposite directions. If it works, it works; I'm just trying to figure out how H&K pulls off their magic tricks
"The surface hardness of HK steel has been historically responsible for its tendency to grudgingly accept traditional blueing (and even plating) jobs. This is responsible for plum P7 slides, and the red/purple extractors and slide releases found on the newer generation of offerings."
Since I'll go out on a limb and guess they aren't case-hardening their parts, that could explain why that P7 let go as dramatically as it did through brittle fracture, or whatever the heck it was (God only knows how they got stresses high enough to get to that point, though)
