    what SIZE dot in a pistol red dot sight?

    i would like to hear from those who have or are, using mini red dots such as the Delta Point or Trijicon on their carry gun(s). what would you recommend, the smaller, approx. 3 minute dot, or the bigger, approx. 8 minute dot?

    my purpose would be self-defense at distances from 10' to perhaps 30'-50'.

    I would go with what best suits your eyes,but at 50' that 8 minute dot will just about cover a torso.

    self defense and past 21 feet is kinda hard to understand

    but if you think you need a red dot in a SD sitaution.....8 moa cause the faster you cover the target and squeeze the trigger
    the better you chances of being able to help in your defense

    wast of time in a gun fight trying to find the dot and time against you kills

    the time you spend practicing to get the dot on target should prove to yourself that the dot isn't needed.
    a bright sun or refelection may wash out the dot---and you waste time looking for it instead of shooting...
    or the BG is wearing a red shirt
    or the sun is in your eyes

    practice with it and a timmer;
    than without it and a timer.

    upside is, either way you are practicing and trigger time is good (going with you know the proper drills)

    i have a 2moa on my bullseye gun, a sig trailside for 25 yards
    a 3 moa attaches to my 45acp for bullseye (25 yards) and silloute out to 100 yards.

    good luck

    I have Trijicon RM02s with the 8MOA dot on two of my pistols. It seems to be the most usable compromise between speed and accuracy, the 3MOA dots are just too small to pick up quickly. My patrol rifle optic has an adjustable dot that goes from 1-10MOA, under 50yds I keep it set on 10, it's faster and still plenty accurate.

    Remember, an 8MOA dot covers an 8" area at 100yds, 4" at 50yds, 2" at 25yds, and so on. It's not as big as it sounds. Also, if your gun is set up right you'll have taller "suppressor sights" that will cowitness with the dot, so no worries aout the optic failing, etc.

    This is my FNP-45 Tactical and FNS-9:

    I'm running a Trijicon RMR02.
    RM02 RMR - Trijicon, Inc.

    wast of time in a gun fight trying to find the dot and time against you kills--unless your opponent is in cover and only partially exposed.
    a bright sun or refelection may wash out the dot--been indoors and out, and outside is actually brigter.
    you waste time looking for it instead of shooting--if he's close enough to point shoot, point shoot. If there is sufficient time and distance (same time/distance that you'd use irons) use the dot.
    BG is wearing a red shirt--dot is still visible on red target, should be visible on a red shirt.
    the sun is in your eyes--that would be the same for irons as well as dots.
    practice with it and a timer--good advice. especially the "practice" part. Speed is fine, accuracy is final.

    ymmv.

    Ditto on what jdsumner said. I have a 7.5 moa delta on my DeltaPoint, and the top of the triangle makes a very concise point of aim, regardless of distance. Why does 21 feet continually get mentioned as the outside range for SD? If I am taking fire at 50, 60 or 100 yards, I'm shooting back.

    Consider comparing it to a triangle before buying one. I did, and was immediately impressed with the delta vs the round dot.

    8 MOA equals 8 inches at 100 yards, so the dot would be a little less than 1.5 inches at 50 feet... maybe cover a very small torso!

    Yep, and at that same one hundred yards, the top of the delta aligns perfectly with any point on the torso one chooses.

    Who does the mount work to put an RMR on the pistol slide? I have one mounted on my Mossberg 935spx shotgun. Might want to go to pistol mount.

    Depends on the pistol, not all slides can be machined to accomodate an RMR. FN sells the FNX45 Tactical and Competition already set up for mini red dots and S&W is just coming out with a line of M&P pistols that have factory milled slides.
    Check the sites below, they sell guns already set up and also offer milling services to cut your slide.

    So what type of mounts are you using for the Trijicons? They look almost flush mounted.
