    I'm looking to put a red dot optic on my STI Marauder and am wondering whether a 3MOA or 6MOA dot would be the best option. Basically this will turn into a race type gun, which I'll be looking for quick follow up shots and precision on target. For precision I'm reading a smaller dot is better, but for quicker follow up a larger dot is better.

    So what do size dot do you run on your gun and why do you like it vs a different dot? Thanks

    Once I decide on a dot size I need to decide between a Trijicon RMR vs a Vortex Razor. I like the larger size of the Razor compared to the smaller Viper option. Plus the Viper only comes in 6MOA.

    I went with a type RMR with a 3.25 MOA dot (RM06, adjustable) for an EDC Glock 19. I tried a larger dot on a pistol at a training class before buying my own. Both are great; if the advantage of the larger dot is seeing it, one can turn up brightness of the smaller reticle to get a bit more flare and visibility. Because of that, I would make the same choice if I did it over again.

    I have both a Vortex Viper in 3 MOA and a SIG Romeo 1 in 6 MOA. I like the 6 MOA much better. It is easier to reacquire at speed.

    I use an 8MOA for SCSA and bowling pin matches and a 3MOA for long range target shooting.
    Here is a comparison I made for shooting pins at 25 feet.

    I tried both and chose the 3.25 and use it on my duty gun for work. It really is just personal preference. I shot both dots against the clock and the splits averaged out to nearly identical, but I know most competitors choose the big dot. I can bloom the small dot to pretty large looking when I turn it up all the way.

    This is a great graphic that helps a lot. Looking at this I'm leaning towards the 6MOA dot.

    I have both the 3.25 and 6 moa also and prefer the smaller one.

    I use a 2.5 Leuplod delta point for USPSA, it is the best dot I have seen. I try the Sig 3 MOA Romeo and a vortex 6 MOA, and the delta point is hands down the better dot. I have shot a few of the Trijicon RMR 3.25 MOA site and I really do not like the dark tinted glass at all, and the smaller window make the dot harder to track.

    Not sure if there are other dots that can do this but the C-MORE slide ride or railway has replaceable diodes that cost about $50 that allow the user to change the dot MOA. The more expensive and better built RTS2 is like most, fixed MOA. One fine point about dot sights, in general a good sight will have a brighter more crisp dot compared to a budget model. Good sights start at about $250 and go up from there. I think but cannot prove but I believe a 6MOA is a good compromise for those that want to shot USPSA and Steel Challenge using the same gun.

    My experience is limited to C-MORE and Burris. Both are good as far as quality. In a weak moment I bought a $50 Sight Mark and used it just once. $50 does not buy much of a sight. I use either 6 or 8 MOA for SCSA and USPSA/ICORE. My eyesight isn't very good and I'm not at a place in time where I have a chance of winning major matches but I'm ok, middle of the pack. If I were younger and looking to be a champion I would probably be using a 3 MOA.

    Last week I set up one of my G17s for Carry Optics. I have no real experience with this division. After much internal debate I decided on a dovetail mount for a Burris FF3 that I had mounted on another gun. First time out to sight it in at the 10 round mark the battery cover (and battery) went flying. This is really my fault I didn't have the cap on tight. Found the battery but the cap it appears is lost for all time. Sent Burris an email asking about a new cap, within 15 minutes a reply with a tracking number, 3 business days later the gun is back in service, no charge.

    A dot sight is not magic. You need to practice, especially dry fire to train yourself to quickly acquire the sight picture. I think it took me about a month to get reasonably good at it but I'm a slow learner and I have to keep practicing to maintain the skill.

    I prefer a small dot.
    The larger dot bounces less, easier to find when shooting at speed though.

    Get a C-More and change the dot yourself by changing the diode back and forth for fifty bucks.

    I believe this is what sti use to put on their race guns.

    Any chance you can add what a "normal" front sight looks like in comparison?

    I'll see what I can come up with, I prefer normal black Patridge sights.

    Here is my best guess with my 686 S&W with stock sight held at arms length (22" from my eye to rear sight blade). The rear blade appears to be about 9" wide at 25 feet. The bowling pin is 4.677" wide at the widest point. My 617 has a custom rear sight and it looks about 12" wide at 25 feet.
