    Red dotting a S&W K/L/N/X frame

    Watching @jetfire Ďs IG page and his ACRO equipped L frames has got me thinking about putting a dot of some sort on my 67. My question to the hive is about good RDO mounts available for the S&W that folks have experience with.

    Jetfire is using an Apex Taxtical mount and an ACRO. Hereís the mount:

    Trijicon also has one:

    And Iíve found this one from Allchin Gun Parts:

    I really like the Allchin except it doesnít have the raised bosses like the Trijicon does. And Iím not interested in an ACRO and Apex isnít making one of those for the RMR footprint so theyíre out.

    Any other options you can think of? I want something that uses all 3 screw holes.

    That Allchin mount looks really good. All three screw holes and a recoil lug make feel like itís designed by someone who takes this seriously. I have used the Trij mount and itís rock solid, but I wouldnít be afraid to go with the Allchin.
    I shot the PX4 before it was cool.

    Somehow I missed this thread:
    https://pistol-forum.com/showthread....red-dot-sights

    I really like the looks of the Allchin and the Raptor Engineering mount.

    I posted this question in another Revo hive full of USPSA shooters.

    Allchin was the hands-down favorite, mounting the lowest.

    I have a Raptor Engineering on my 617(pics in the above thread) and like it a lot. Machined in posts for support and 3 screws for secure mounting. I've used it on borrowed guns (686 and vcomp) with success.

    My buddy recently got an allchin for his v comp and I didn't like the fact that the posts aren't machined in but are small polymer inserts. It did use 3 screws for mounting though.

    My raptor was for a vortex and his allchin for a sro. If raptor's site comes back (down for wildfires) I'd buy future mounts from them but so far the allchin is fine as well. Being that they're different optics, it's hard to get a height comparison, but neither is noticeably higher than the other aside from the difference in optics.

    I don't know how important the posts are for a revolver since the dot isn't reciprocating though.

    Iíd guess theyíre really important. The frame is moving violently in a given direction under recoil, and the difference in inertia between the sight and the frame makes it want to move at a different speed. Posts are always better for load than screws.

    So the posts are super important. All the Ruger mounts on the market use a single screw and a recoil lug, and none of them hold zero with even 38 Spl loads. The three-screw S&W mounts are rock solid.
    I shot the PX4 before it was cool.

    So given the views above, the allchin would be an inferior mount to the raptor or other options that have machined posts since the example on the vcomp uses polymer inserts and they aren't exactly press fits or anything tight fitting. Hopefully raptor is back online before I need another mount.
