Question: Could you please tell me exact length from end to end? Thank you.
Document: First of all, this is a basic light. If you are looking for something more, look elsewhere. It does not have a momentary on, nor does it have a strobe feature. It lights up, that is allI bought this light for my home defense weapon. Glock 22. Whether it is really 200 lumens or not, can't tell. I can tell you that it lights up any room that is dark. It is fitted snug on my weapon.
It held in place. Light comes on when I need it to, turns off when I turn it off. 50rds through the gun and it still works. Time will tell in the long run, but at less than $40, if I can get another 300rds out of it or 1yr of use, I am ahead.If you don't expect this to function as a Surefire this will be a great value to you. This is a flashlight that mounts on your gun. Nothing more, nothing less.
A very good one of 2 AA flashlight (another typical solid and well made from JETBeam). It much much brighter than my 2 AA Energize LED flashlight (from Target).However, it's not appear as 240 lms, the rate could be the LED, not real output.
The release switch also has a tendency to pinch you when you try to remove the light, since it requires so much force. I have no doubts that it will stay attached during firing, although I do doubt that I could easily remove the light under stress.I had no problems with it turning on by itself when I set my pistol on its right side, although the switch does depress halfway.
Light is bright and mount releases easily, but I could feel it moving on the AR's grip rail. Nice and tight on Glock 21. I would have left it on the AR if I didn't get a bigger one. As another customer pointed it out, this light is not supposed to hold up after hundreds of rounds at the range, unless your serving warrants its supposed to be there in case one night there is an intruder in your dark hallway.
bought this for my walther 40cal & i must say am very pleased. the light is very bright & lights up my entire house in the dark & its well made & fits nicely. the only downside is thats its closer to 3inches in length rather than 2.5 but thats ok, im still happy with it
I was a little concerned that this would be sub-par but I'm very happy with this light. It fits very snug on Glock 17 Gen 4 and extends about 3/4&#34; beyond the barrel end. The light beam is fairly tight with the center being matched with the sights; perfect. Seems well built and tough. Good buy!
very good construction, VERY bright, solid all around. my only gripe, not a quick detach on MY weapon because the weaver mount on this light is just a little too tight. i have to unload gun then yank (and i mean YANK) this thing off; which, if i needed to take this off quickly in a tactical situation, would make it a little impractical. on the flip side, however, i guess it won't move while i shoot.
the button for the QD is easy to press down and when it locks into place there is absolutely NO wiggle room, in fact some other users have had issues with it being too tight and hard to take off, but it is perfect for me. All that does not matter if it cannot stand the violent action of firing, so today I took it to the range and ran three magazines through it.
springfield xd 5 in fits well very durable slides on and off with ease and is very bright well worth the price
