For you and others who might be interested, there is a Kel-Tec Yahoo eGroup similar to the TFA Yahoo eGroup at:
This group is pretty active and probably post 900 to 1,000 messages a month but it does have some interesting stuff. I picked up the idea of using a pencil eraser as a trigger stop. I did have to use Brownells "Accra-glas" to keep it attached (it popped right off with regular epoxy
I would guess the 9mm would also be a fair handful with +P+ loads as it, like the old P40 is an 11 ounce gun shooting high velocity ammo. Glad to find the Kel-Tec people are still doing a good service job. I would like to add the tritium night sights they offer for about $80 with a lifetime warranty. Like you, I haven't had any problems with my two P40's
I haven't had much luck in keeping the trigger shoe in place. The recoil pops it off after a few rounds. May be peculiar to 40S&W rounds.
I doubt a child could pull the trigger on a Kel-Tec because it is long and pretty heavy but then I wouldn't leave it around for a trial test .
That would be a really dumb stunt. With the long trigger pull I doubt anyone is going to fire it "accidentally." I've always carried my 1911's in condition one, cocked and locked. As Dr. Bryant pointed out, it doesn't take one with evil intent long to cover 15-20 feet and you need to able to use the gun when necessary, not ask for a "time out" to load it
But that's another subject area.
Have a great Christmas and a Happy New Year
