Great light - Crimson Trace Lightguard Springfield Full-Size XDM XD Gun Light

I must say the Lightguard is a great little light. It fits the gun well and has a very intuitive activation. It uses a very broad light beam that lights up an entire room without being so bright as to have the light bounce back at you the way I have experienced with some other tactical lights. This also means it does not reach really far outside and does not have a center bright spot that can be used as a rudimentary pointing or close range aiming device. It will however light up the entire main room of my house from the front door without the dim areas around the sides.
I was surprised at how much weight it added to the XDM. We are not talking bricks here, but it is noticeable. I like the extra weight.
The only negative I have is that it has no off switch. This would be very helpful in some situations as the light can not be removed without disassembling it.
Over all I really like this light. Add an off switch and it would get five stars.
