How do I take off the red dot scope from my sig 9m?

I use a 22 cal rifle laser on mine , the 22 is nearest the same diameter to the bolts I use so I can lay laser right into same bolt bed on frame that bolt normally rests in , then bench rest bow and get into shooting position then adj scope to bring crosshairs/ reddot onto laser dot at white target board , try to adj at distance you'd comfortably take a shot at

No, that doesn't sound stupid. It's always a good idea to get all the information before using firearms and their accessories, and I'm happy to help:

The large knob on top of the scope is the rheostat, which is used to turn on the red dot, and adjust the brightness. It can be adjusted from "1" (dimmest) to "11" (brightest). You'll have to be looking straight down the scope to see the red dot, since it is only visible when you're aiming. If you turn on the scope to the brightest setting, and you look through like you are aiming, and the red dot is still not there (or very dim) then you probably need to replace the battery. It uses a 3 Volt coin-style lithium battery, type 2032. Unscrew the battery compartment on top of the rheostat and put the new battery "+" side up. Then replace the battery cover, and you should be good to go. Turn off the scope when you're done to save the batteries.

Since you bought the rifle with the scope already installed, it's probably already sighted in, or pretty close to being sighted in. Adjusting the windage and elevation on the red dot scope works just like other rifle scopes. The knob on top moves the point of impact up/down, and the knob on the side moves left/right. For this model, each click of adjustment moves the point fo impact by 1/2" at 100 yds, 1/4" at 50 yds, or 1/8" at 25 yds.

Be safe, and have fun!

the best way to sight in your red dot is clamp your gun in a gun vice or work mate? so it cant jump about!!!!!!! look through the barrel at a post say 100yds away then tweek the red dot or croos onto this post,,then test fire the gun and tweek the scope till its shooting were it points,,easy,,,
dont let the gun move at all,,,,you need to remove all the wobbely bits,,your the bigest wobbely bit?
an im not being nasty,,,you cant tweek a scope hand held?

Take the scope to the battery store with you. I would bet that it is a 2032.

My leapers show green dot but will not show red dot

can you be more specific, what is the name and, model number of your optic kit, is it leapers?

take out the battery or batteries.
turn the scope on to full power.
place the battery or batteries in the scope.
just start the battery compartment cover onto the threads.
watch through scope as you slowly tighten cover.
If the dot lights up stop turning cover or experiment with continuing to thread on cover.

that is the problem with red dot sights.if your eye sight is not 20-20,you will get a star burst or halo.glasses will help.

The PDP3CMP uses the CR2032 batteries.I had one and gave it to my son who uses it on a huge pistol.I gace him several spare batteries with it.You always need a spare for those things.Good Luck
