Thread: Are BUIS necessary on a defensive pistol

    Are BUIS necessary on a defensive pistol

    While I have BUIS on every defensive red dot pistol I have carried, are BUIS really necessary?

    On a carbine, due to vast experience and high levels of reliability I have been known to go without. On a handgun, I’m not sure we’re there yet. But close perhaps.

    Yes, 100%

    Has your dot ever:

    Not been turned on when presented to fire?

    Not been on the right setting for sun / ambient light position?

    Not been visible?

    Needed PM at a very inopportune time?

    Had a loose screw / screws / mount?

    Fogged lens?

    Flickered?

    Had an emitter obstruction?


    So far, this is my personal list of RDS failures.

    So again, yes, 100% to your question.

    Just because it "feels good", doesn't mean it's best.

    I think you are answering a different question, which is do dots fail, and the answer is obviously that they do.

    My question is what are the circumstances where BUIS would allow you to be successful, and you could not otherwise get the job done through pure index or using the optic as a big ghost ring? I don’t have BUIS on most of my competition pistols, have had multiple failures in matches, and have always been able to finish the stage. Heck, for the first six months YVK shot CO, I don’t think he used the dot on most of his shots, and he still did pretty darn good.

    Following.

    Due to a lack of experience on my part, I had my G48 slide milled for a 507k, but opted to have them remove the rear sight dovetail. So my EDC G48 has the optic, but just a steel 0.156" front sight. I've shot it with the vestigial rear "sight" molded into the Holosun and the front sight, so I know where it shoots (top of front sight) without the dot. I suppose sometime I should turn the dot off, and do some testing to see how / whether I can index using the optic as a ghost ring, as GJM says.

    Very interested in this discussion.

    If nothing else, the irons are an easy daily check to make sure the dot is still zeroed.

    Busted. Now you know why I asked Stoeger what to do when I don't see the dot over the target. He said, more or less, "send it" so that's what I been doing.
    “Well," said Pooh, "what I like best," and then he had to stop and think. Because although Eating Honey was a very good thing to do, there was a moment just before you began to eat it which was better than when you were, but he didn't know what it was called.

    Is it possible for dot to move without change in adjustment screws position?

    If the mount shifts or something internal breaks.

    This is a Shield Plus with a RMSc, which offers perhaps the ideal BUIS arrangement, because regular height iron sights can be used, and the RMSc display is so clear.

    I am pointing at an electrical outlet at six yards.
