I bought an HK 97M8 in 1985 and I have stuck with it. At the time I think it was the smallest 9mm out there from a major manufacturer. I can CCW, but it's fixed poly barrel and overall high quality made it a very accurate pistol so I wasn't sacrificing anything for that compactness.
I also thought it was the best answer ever for the safety debate. I didn't worry about having to remember to take the manual safety off, on the other hand I didn't have to worry about it being cocked on a live round. The trigger is great - I never had to deal with DA/SA or DOA issues.
As much as I like to fire other pistols, I don't train with them. I "train" only with my HK P7M8. I know I can't use an SA pistol for for SD. If I were ever in a critical situation now and had one, I'd be sqeezing both the grips and the trigger and nothing else. I would have to do a lot of re-training. And there are issues with other pistol actions... decocking and all that.
I've loved this pistol from the very start. I wish now that I had purchased 6 of them, one to carry, one to keep by my bed, one to keep in my car, one to take to the range, one to just have in the safe so I could say to myself "HK P7M8 NIB NEVER fired - worth $1975 he he he he
" and one to put under glass so I could gaze fondly at it's beauty from time to time.
BTW.. I read a lot of talk about "break in periods" for pistols. I have never had a failure of any kind with this pistol period. I've never put reloads through it, but I've used almost every major brand of ammo from 115 to 147gr and never had a problem.
