I purchased my Viridian C5L, 3 extra CR2 batteries, and the Tac-Loc holster for my XDm 3.8 Compact 9mm. This was after reading tens of reviews on this and other gun forums, vendor websites, and youtube. I decided that although the X5L would be brighter, I was not willing to have the flashlight bezel protruding past the muzzle, since this gun is my CCW.
I ended up purchasing mine from www.xfighterdefense.com
because I found the cost relatively cheap at $264.99. The cost for 3 extra batteries from the same vendor was $5.99. I was worried about dealing with a company I had not previously heard of, but another XD Talk member recommended them, so I took the risk. I am not disappointed at all. The package came within 5 days of the order. Everything was secured properly in the box and it came with a nice letter from one of their representatives.
The laser kicks a$$! A ton of my friends have Crimson Trace products and they cannot use them at all unless they employ reflective tape, it is getting dark, or is very overcast outside. I took the C5L out in direct sunlight last Friday and it was amazingly easy to see. I cannot comment on long-term hold of zero, but I can testify that mine has held for its first 150 rounds. I zeroed mine at 12 yards and with laser only, had one large in each of my targets, with diameter about 4". Green definitely IS the way to go. At night, the laser is ridiculously bright.
The flashlight is appropriate for close range use, as should be expected. One can not look directly in its direction without feeling overwhelmed, especially on strobe mode. Friends commented it made them feel disoriented when I pointed it at them (before being mounted on the gun, obviously).
Lastly, for the Tac-Loc holster... I am not so impressed with it. Although it securely latches on the C5L's thumbscrew, the "combat readiness" feature, which is supposed to turn the laser on when the gun is drawn from the holster, does not work. In fact, I can not even see how it should work. If I am mistaken and there is another version of this holster that does what I am saying, then shame on me for not understanding the sales literature, I guess. I am not freaking out about it because it is only a temporary holster, until I can get a custom, tuckable one made.
Update... it turns out was not using the Tac-Lock feature of the Viridian holster properly. When you holster the gun with laser activated, the holster turns off. Then, when the gun is drawn, the laser is activated. Since the holster is open-ended, you can see it go on & off from the muzzle end. Strangely, the mechanism does not work in reverse. In other words, if the laser is off when you holster the gun, holstering it does not turn it on. This puzzles me, since the Viridian buttons are simple A/B toggle switches. Oh well, when operated as the instructions state, it works as claimed!
