Now let's fast forward to today. Primary Arms has an email distribution list. I would suggest you get on it. They send out deals as they happen and it just so happens that I got the light shown above for $89.99. I live on 1.5 acre plot and there is about 2.5 clear acres between my house and my parents. The other night I got a phone call from my parents stating that there may be a deer that got hit by a car suffering between us. Well I grabbed my rifle, some hollow rounds and headed out into the darkness. The TLR-1s casts a beam of light that enabled me to see 2 acres in the darkness. This light for its size far exceeds my expectations. With the steady on function, momentary function or even the strobe function this little light is a wonderful addition to my rifle.
I would like to add that I am sure if you had a full size pistol with a tac-rail this would more than likely fit. I have an XD 9 Sub Compact and this particular light is too big and will not work, but that is not what I bought it for. I bought it for my rifle. The only advice I have regarding the strobe is if you are using this feature in your house performing a sweep, make sure you do not paint light colored walls or you will learn first hand why the strobe feature is unique.
In this video, you will see the light's point of view, then the bad guy's point of view
