BS on all of that crap.
It aint a toy. If it has any issues get rid of it, You can not bet your life on something that does not work. That includes the GEN4 GLOCK. They dont work right either. I have a Glock GEN3 shot it with all kinds of ammo and never missed a beat. Hell thats one reason you pay $1 a round for defence ammo. GET WHAT WORKS!!!!!
