Leaning towards the 1 but I like the laser option of the 4.  Not sure it has enough lumens tho.  Anyone have input on these two lights?

I have both lights and the only reason i have the tlr4 is because my rail wont accept anything bigger. I find the laser an annoyance as it is a pain to zero and if it is pushed in either direction on the rail of my m&p40c it will shift the poa. The tlr3 is a better option as it doesnt have the laser and it is also ipx7 water rated. The tlr1s is better all together if your weapon will accept it as it is brighter and can accept more accessories. The tlr1hl is better than either IMO.

Awesome, thank you.  I picked up the TLR-1s yesterday for $100.

I have a few TLR-1s (standard non strobe or HL) and a TLR-1 HP (rifle mounted when hog hunting) and IMO the TLR series (mostly the 1, 1S, and HL) are some of the best bang for the buck weapon lights out there today :)  Good choice :)
