My M8 is awesome. I bought it to carry and it fullfills my expectations. Slim, single action trigger /w an awesome safety device (cocker) that allows me to carry one in the chamber w/o out a second thought. As with my other HKs, it works. You put ammo in it and it goes pow every time, all the time. Great accuracy with the fixed barrel.
Now on to other pluses: this pistol will hold it's value more than most other quality firearms. It's HK built. The "expensive" cost is relative when you take into consideration how well it will function, and how it will retains its value, especially when not in production any longer. Can anyone say "appreciation".
Although I always lock up my firearms, with 3 "little ones" around the house the added safety of the cocker and the ability to remove the firing pin/bushing with a twist of the finger makes it practical in a family environment.
It does get hot and I always take a second gun to the range when practicing /w it so I can give it a rest. It is a little heavier when compared to plastic and aluminum frame pistols, but I like the solid feel.
It's my EDC and I love it...it also loves me.
