Great product - Viridian X5L GEN2 Universal Green Laser Sight with Tactical Light

I put this on a SigSauer P320 Full Size and it fits perfectly, just the right size. It is not too heavy, does not overwhelmingly weigh down the front of the pistol, and it was very simple to mount to the rail and get set up with the online instructions, which cannot be lost because they are not printed in a tiny book in five languages. Programming the laser and light was simple also and both are very bright. Fired 150 rounds of Underwood ammo 357 Sig through the gun with this light and laser combo attached and experienced no shifting point of impact, no breakage of bulbs, and no durability issues so far and that's some pretty punchy ammunition in a polymer pistol. The mounts did not loosen either, which is always a plus. The only drawback I can find is the availability of holsters but I intended to use this pistol for home defense anyway so that's irrelevant to me and I'm sure that the aftermarket will catch up or custom shops will step up to fill the vacuum if not.
