I'm getting back into the hobby and I haven't fired a semi-automatic pistol since 2010. My over all experience with semi auto pistols is pretty limited, I was a revolver guy. I probably have under 3000 rounds through semi autos. A G19 MOS with a Shield RMS has found its way into my safe.

I mounted the sight, put 30 rnds each at 15, 35 and 45 ft standing using the red dot to see where it was at... and I can't tell how to adjust the sight.

I can tell I'm messing up a lot of shots from inexperience. I've never shot a Glock before. I could tell by the time I was shooting at 45ft my arms were tired. I'm trying to stick with "the gun going off should surprise you" every time but still feel like I'm squeezing a lot of shots. Here is 15ft, here is 35ft. These are 12x18" targets (all I had).

Should I try to find someone at my range with better skills to get it set?
Should I not worry about it, consider it already set more accurately than I will notice? Shoot it as is until my groups get smaller?
If I'm understanding this correctly, my 8 MOA dot should be about 1" at 35ft? Could I get one of those laser boresighters for rifles, set a target at 35ft and center my 8 MOA dot over the laser dot on the target? Is there a rest for that purpose? Am I over thinking it?

I cowitnessed my RMR dot with my supressor height sights. But 8 MOA seems quite big for a RDS.

The Shield RMS is small enough that I can see my stock Glock sights through it. In fact, the back of the RMS body is cut out to be used as a back up rear sight if the optic fails.

So you're saying I should adjust the dot to be halfway above and halfway below the tip of the front sight post when I've got the glock sights lined up?

Sorry for the dumb ass questions.
 
Zero it the same way you use your sights Ie:

Put the dot in the same place you put where you want the bullet to hit now

^^^^ What Dilligaf and Shawn said....For Glocks/Sigs, I use image 3 in Shawn’s diagram...combat sight. If your sights are stock, non-suppressor height, I’d zero the dot directly over the front sight, just resting on top and start there. If they are suppressor height, have the dot cover the front sight.

That said, for a guy relatively new to the platform, using an 8MOA dot for the first time, I wouldnt be disappointed with those groups. You are not going to get the same level of accuracy you are used to with revolvers for some time. Your 35ft group looks like a solid starting point. I’d say your sight is mostly on target and you can fine tune later once you get more practice and your groups get smaller.

Adjust the optic the same way you would adjust any other sight. If the group forms low and left, adjust up and right.
Of course, you will need to have nicely defined groups.
I would suggest that if you are shooting with an optic, you should be unaware of any iron sights in the sight picture.
 
Looking at your groups I'd say that your sight looks to be pretty well zeroed already. Glocks are a different beast and, as mentioned by Innavedaw above, will be tougher to shoot accurately that your revolvers. I'd leave the sight as is and practice more to get more used to your Glock.

Its the total opposite, Just like an AR you wanna line up that dot with the front post. Even more so on a pistol due the the short sight radius. The only advantage to a RDS is your eye picks up that dot way faster from the draw helping you make faster shot on target. While having both eye open and focusing on the target.

While I find that being able to see the front sight through the RDS helps in not "losing the dot" when bringing the pistol up you should not consciously be using the dot and sights together when aiming, either for a pistol or a rifle. Just raise the gun, focus on the target and place the dot where you want your rounds to go. Bringing the irons into the mix will slow you down.

He wants to shoot groups, so speed isn't the issue. But let say im shooting behind a barricade on the draw, then yeah once that dot appears on the target its go time. But lets face it most guys here shoot groups at staic ranges so they can line everything up and see what that gun can print.

Iim around 2K+ rounds with my RMR and im still getting used to it. But It does shine when shooting in awkward positions :)
 
to sight my rmr in I got a laser round,I chamber it at home,pointed it at a wall at the approximate distance I intend to shoot and adjusted the dot on the rmr until it overlapped the laser dot,worked good for me and took all of 2 minutes.
 
On mine , 6mm dot , turned down small, I clamped the gun frame , padded in my vice, pit a target up on e wall , about 40 ft, lined the gunsights up to the target, than mounted and zero the red dot, If you don't have iron sights, that will not help, but for us old blind guys these things are great, now you can work on trigger control, and not try to find the little black sights
 
Thanks guys!

I didn't notice while shooting because I was totally focused on the dot, I was not lining up the Glock sights, but checking it here at home the dot is already somewhere between shawn's image #2 and #3. I guess I just lucked out that it bolted on basically cowitnessed. I will keep shooting it, get more practice and tighten up my groups before I make any kind of adjustments.
