A decent laser with some fitment issues - Lasermax Laser Sights for Springfield XD/XD(M)

I was looking for a laser for the XD-9 Mod.2. I felt a guide rod version would be best and would allow me to carry my weapon with the current holsters I own. Upon installation, the guide rod, even with the cap for the XD-9 installed, barely remains in place. I was able to get it installed and rack the slide a few times without it locking up. The guide rod at first would not stay in place, but currently seems fine. I'll have to see if putting several hundred rounds through will show this to work as it's supposed to. The other item that could be better is the take-down lever, which is replaced with one in the package. It must be installed perfectly before the button that turns on the laser, from either side by the way, will work. That was not an issue for me, but for others. Have used the laser in dry firing thus far to become acclimated to it's function and placement. Very bright and usable as a way to acquire the target is low light situations. It also flashes, which is said to be better for the eyes and to prevent others from zeroing in on your position (unlike using a flashlight).
