I had the sig one and the tlr-1...I am going to have to buy a tlr-1s. The TLR series is the sleekest, best quality out there in my opinion. Buy it off e-bay from an american reputable dealer so you don't get some clone piece of garbage and save 50-100 bucks over Canadian dealers to your door. Although, if you want the one with the laser they may not ship to Canada. Buy quality once, it is much cheaper in the long run, especially with a light that can be transferred from gun to gun. I even use mine as a flashlight, helped me change my tires at 11pm the other night!
If you really want a laser, the best one out there are the crimson trace grips. I had those on my Sig and they were amazing. Again, ebay, authentic with warranty for 299.00 to my door.
