I have been through about six 250 round boxes of the yellow box in .40 and have not had a FTF yet. Come to think of it the only FTF I have ever had was .22LRs, I just chuck them as far away as I can. I guess I am not shooting enough...

I had a revolver that had that issue. You may check the firing pin for wear, or the springs. A gunsmith could tell you with a few quick measurements which is part is off a little.

Normally I'd agree but I suspect there are probably some additional factors. I strongly suspect it could just as easily be my big hands impeding the slide just enough to prevent the slide from completely returning to battery. The reason I saw that is this is a pretty consistent behavior with my G19, 23, 34 and 35 that I never have with the 1911s, Sigs or HKs...Just the Glocks. The failed rounds show evidence of a light primer strike but, it only happens with the UMC brand of ammunition.

Then I feel I have to put the round somewhere safe so it doesnt go off! Just freaks me out! OR CAN IT???????

Please give the ammo the does not go bang to me for proper disposal...I'll take one for the team and risk my life with that faulty ammo during my next range session. Seriously, most of the time, it's just fine to cycle that ammo again. About 1 in every 50 rounds or Remington UMC "Yellow Box" ammo will fail to ignite in my Glocks. Assuming the immediate action drill doesn't launch the rounds into a black hole, when I recover those rounds I just stuff them in my magazine again. They usually go bang the second time around but, sometime they don't.
