If you look closely at the picture you will see that the grip is a Crimson Trace laser grip LG-344

I had to grind the hump around the top rear screw hole on the opposite side down, the first time I shot it after 20 shots it had bruised my thumb joint so bad that I could hardly move it for a month.
I am shooting it with these grips in the second vid clip for sure can't remember for the first one though I'll have to go back and look. OK just looked it is hard to tell but yes they are these same grips. One other note is I didn't have the laser turned on in the first vid and did in the second vid.
Here is a picture of the other side before I ground it and one of me staring down a grizzly...
