Morning folks.  Hope your all doing well. 

Ive asked this on FB and was told the X300UB fit the TCP single groove rail.  But when I tried to fit it, the light touches the trigger guard.  I'm not sure if the X300UA quick release version show mounted in the "Handsome Dan" gun digest article is any shorter, but I guess I'll have to keep testing and returning.  But I figured I'd post the question here. 

What WML have you successfully mounted to your TCP?  From the looks of it, the specialist has the groove the same distance as the TCP.  But DW tech support was of no help regarding this, or which lights fit well either.

Thanks!
