Easy to use - just choose the right one - Lasermax Laser Sights for Springfield XD/XD(M)

Not my first LaserMax laser. Have one on a Glock 17 so installation and use were familiar. harder to install on XD because installation of new take-down lever required following directions EXACTLY. If you do so, it's easy tho'. Love the ease of activating and deactivating laser but will not have the various options found on an external mount such as Viridian. But for a sturdy product that will fit any applicable holster - can't beat the internal mount.
Pros: Internal Mount & pre-zeroed
Cons: Battery change
