I've got 2 lasermaxs.. I love em cause they are right underneath the barrel, pretty much couldn't be more alligned with the barrel unless it was in it, Very accurate out of the box, (unless it's a 1911, then has adgustment) don't know how to make it inaccurate. the switch is in a conveniant location. It's all internal, it'll take the abuse.. Great customer service. Cool and fun laser. these blink, better target accquisition they say. I think u can get them constant on somewhere.
Crimson.. don't have one, but the laser is kinda diagonal from the barrel. So that gives you 2 plains that it can be off. Gotta be sighted in, I think, maybe not. It doesn't protrude really, kinda does, but it's further back than I would want it. I hear good things about it. I'm pretty sure these are constanly on.
What kind of gun is it going on?
Those are the 2 best lasers out there.
My vote is for lasermax. When I was in the same boat as you, The internalness is what made me go lasermax. After having 1, I loved it so much I got another.
I like pics, so here's mine.
I just kinda read that link.. I saw a tv show do something on both of them a long time ago. They are the same brightness, but the lasermax blinks. the lasermax changes the guide spring, I think it's on the weak side, but it has handled +p rounds with no problems. It was designed to handle +P I've gott 2,000+ thruough the G21 and around 500 through the G17. Never had a malfuntion from the spring. My malfunctions happen from the crazy high cap mags I put on. It's flawless when I use stock mags. I just changed the spring after 2,000 ish rounds for $10. good as new. The accuracy claim on the lasermax is +- 2 inches at 60 feet I think, it's 20 meters or something.. It's up to you, u want internal or external? The lasermax is very accurate and will take the abuse. U can probably get Lasermax to give you free stuff, I've gotten free stuff on 2 occasions, woulda been 3 but I never mailed in the survey.
