I just installed my XS Big Dot Sights

    I'm getting older with old eyes to match, so I ordered and installed a set of XS Big Dot night sights on my off duty EDC Glock 27. Installation was simple with the detailed instructions and included front sight/rear sight tool, daralon punch for knocking out the stock rear sight, and red thread lock compound. I did have to file down the rear sight a bit so that it slid into the slide rear sight cut out with just finger pressure (per instructions). Once the rear sight is centered, it is held in place by 2 set screws.

    If I like the sights, I plan to install a set on my 2nd generation Glock 23. Has anyone else installed these sights on a 2nd generation frame and were there any issues with front sight installation?

    Once I get some range time in, I will let you guys know how I like the XS Big Dots.


  2. Just remember that these are not "range sights". The typical response from first trip to the range is WTH did I do? Like anything else, you can get used to them.

    I have the Standard dots on my 27 and I think they are the best combat sights you can buy.

    Let us know how long you go until you start to miss having a rear sight that actually serves a purpose... old eyes or not, big dots are a big gimmick, in no time you'll find that at the same distances the big dots are of any use you could probably hit with a gun that had NO sights.

    (and please, no one needs to post that vid of Yeager hitting the pepper-popper at 100yrds with 'em, given a few shots you can hit one too without sights if you're a decent shot...)

    I have the XS Big Dot sights on my G27 and love them. I have no problems hitting at 25 yards consistently.

    I installed them myself on my 30sf and 2nd gen 19. No trouble installing on either pistol, and no difference in the installation steps.

    Congrats! I've been wanting a set for my G27.

    But, I'm torn between the Big Dots and these. :dunno:
  8. Yes, let us know how you like them. I'm also looking at the XS standard dot, but can't decide on those or the Ameriglo Pro Operators.

    I have Big Dot 24/7's on all 5 of my Glocks. 1-1gen G17, 1-3gen G17, 2-2gen G19's, and 1-2gen G26.


    Love 'em! Great combat sight. Now, I wish I could find the Glock Light I lost!

    3 G27's in the past all with XS Big Dot's. Bought em, carried them as EDC's and sold for one reason or another. Wanted another subcompact again but decided on the G30SF instead. XS Big Dots on the way from midway along with 1000K .45 bullets for reloads.

    Thanks, that's the information I was looking for. I reserved a range spot tomorrow, so I can test my new sights. With the exception of my competition Glock 34, my Glock 23, 27, and 30SF are all carried, shot often and the triggers are all set up the same. If I like these sights, I will be installing them on my other 2 Glock carry guns.

    They take some getting-used-to, but after 100 or so rounds, you will love em'.
    I HATED mine the first range trip, but after that, I could actually shoot better with the Big Dots than the stock plastic sights. I am planning on ordering another set for my Gen 2 G19 asap.

    Installed them on my 2nd Gen G23 without any problems.

    You will get the "they suck" crowd on here soon, but I say use what you want and enjoy. I like them on my pistol and they work perfectly for me.

    Remember they are not easily removed!
    I could not get used to them , just removed the rear.... what a pain.
    I am now looking for a better range/target set up.
    Good luck.

    Just put a set of these Warren Tactial / Sevigny on my G35 and G24c last week. Shot them for the first time last night at an indoor range, and like them, so far. Might be worth a look.

    I was about to ask you where you go shoot that you can reserve a spot, when all at once I realized you were an LEO. Where do you go? District 2?
