Lasers and angles..

I have seen some drawings that show a couple of guns with lasers and how they are aligned whether it is Crimson Trace or an under mount and they show that the laser should be aligned to a certain distance.. and before and after that distance it would be a lot more off..


I know lasers are just a helping tool


but my question is could you not align your laser parallel with your barrel and when you point it at a target the laser would be an inch or so below the hit point if it was an under mount


i hope this makes sense, it is hard to explain but hopefully some can understand or educate me a little bit more about lasers

TRAJECTORY! Bullet leaves the barrel ,goes up then down,
sooner or later the bullet crosses the lasers path, thats why you zero at a certain distance and then you can adjust your aim for closer or farther away shots

I have a CT laser on a Sig P226 9MM at up to 30' i could hit you in the eye ball with the gun by my side. the sights do have adjustments. I have them so i dont have to aim at someone if they break into my house just point and shoot

I saw someone who said they did this w/ their PS90 - but yea, the bullet does not have a perfectly straight trajectory.

I would go to the range and spend some time adjusting the laser.

For me, I would set the laser to be dead on at about 7-10 yards...

Then I would take the target back to 25 yards and see how much compensation was needed...

I have not used a laser sight with a gun before, but I bet that if you calibrate it to 25ft, you can likely bet that the laser on the center of mass will still hit the center of mass even at 75ft...it just may not hit the exact spot on the center of mass at those distances. So if you want to hit someone in the eyeball at 75 ft, you will need lots of practice...

thank you all.. for your responses. I am still trying to learn as much as I can about guns.


thanks again, your responses are appreciated

I had my second range trip with my new Streamlight TLR-2 light/laser. Getting it zeroed in can really take some patience. I got it pretty darn good at 10 yards, but it hits 6" low at 25 yards. I'm not sure if I can get it just a little better, but I'd really like to find just the right balance.
No sense going overboard though, I don't want to spend so much time and ammo getting it aligned that I'm affraid to take the light on and off for fear of not getting it precisely seated the same again.

See, I have zeroed several lasers and never had a problem. But, U must accept that it is only zeroed at the distance U choose it to be.

But as pointed out - if U zero it at 7 yards, it will still hit a person/target at 15 or 25. its just a few inches high.

On my PS90 - mine is above and to the side. So, in my head, I understand how at a greater distance, I must actually aim it towards the edge of a target to compensate for that if shooting past the 7 yard mark that it is sighted in for.

Maybe you should zero it for longer distances where you need to better aim. Let your eyes and the 3-dot sight be your primary aiming device up to 10 yards...???

Zero it far as far away as you would probably shoot and it will be less and less of a factor the closer your target(read badguy) gets to you.
