What do you guys think of the Streamlight TLR-2? Thinking of either going with that or the Insight M6.

BTW - shooting the XD45acp is REALLY nice. Groups are getting tighter as I get used to firing it.

i use it on my xd45. i can't get the thing super clean anymore, but streamlight offered to clean it for free if i sent it to them.

i don't care enough to do that.

never bothered owning one though

I personally think it is worth it.
