I have the Streamlight TLR-2 on my XDm, and I paid over $250.00 for it. In hindsight, I would absolutey stick with light-only TLR-1; the Laser is really not needed for SD with a light this bright; save the money & invest in Heine Straight 8's. You can find the TLR-1 for less than $100.00. It is a quality piece & EXTREMELY bright.
