They have it right on pistol training - easier to shoot, easier to shoot accidentally (if 'accidents' exist in the firearm world, another discussion). I like my SA/DA semi with a decocker. I don't think Glock style striker guns are as safe in hand, on the nightstand, or going in to the holster...
No frame mounted safety, no problem. SA/DA to striker with no problems, however, accuracy may not be as good as it could be sticking to just one operating system - I'll never know.
Nothing says badass like a good waxed canvas satchel, weighs a ton though. Boots are still leather, knives are still carbon for the most part. I really like the look and feel of the classic gear.
Kabar Dozier folding hunter models are slim, light, inexpensive, hunter OJ, and do the job. I've not found a situation that this 20$ blade couldn't handle (edc/trade type job). IMO, good place to start.
