Well I told the Deputy that the light I got from him wasn't the one (TLR-1 HPL) he said he had.  The HP didn't give enough side spill for me but it was lighting up road signs over a block away so bright you almost thought the reflection was from the Sun!
Any way I sent him a message explaining it to him and he said he would tear up the check no problem.  I knew he would, but dang it I wanted a light on there NOW!  Oh well, at least now I'll have the one I wanted.  Now to settle on optics.
I think I am gonna run Federal HST loads through the CX4.  I am wanting to get the 147 grain, but the 124 would work ok.  I sent Federal an email asking what the ballistics would be for each load out of a 16.6 inch barrel.  We will see if they respond and what they say.
