I have a TLR 1, I looked at the TLR 2 before, expensive little light the TLR2 is lol, I would hang up on the laser portion IMHO, I found that any weapon Ive use a laser on, I always looked for the laser for aim dependance, so I stopped training with them, finding holsters for the TLR2 is a bit of a nightmare too. IMO if I were you, I would stick with the light. If however you choose to go with a laser, it depends on which you will use more, the light or the laser, if you are looking to use the laser more, sacrifice the light power for the dependable, easier to see green laser, however if youre depending on both, go with the red laser and 600 lumen light.
My TLR1s has never failed me, great light, decent price and looks amazing on my gun, very easy to use and attach, was able to put it on my M&P right out of the box without having to change the attachment piece.
