I guess this is why we all aren't driving black Model T's !!
As for the size...it isn't as big as you think it is!!
Wait...did I really say that?!
Anyway , I never saw the want/need for one until I actually ran one for a bit on my tactical rifle.Just "blade" the hand up and palm it down. It really helps me when the temps get down and the fingers are frozen.
To each his own; just thought I'd see what I could do on the cheap.
thx
wes out
P.S. The GF says some of you guys just have "knob envy"...HA!!
