    Can an OEM Glock slide be drilled and tapped for a mini red dot sight? I have a Leupold DeltaPoint. Lone Wolf only performs this on a stainless steel slide, not an OEM slide.

    Anybody local who would do this?

    So they mill dovetails into it or do they mill it and then drill and tap for a intermediary interface?

    That was code for if they do the latter, then it's quite likely that it's OK to drill and tap that steel in that application.

    Though I dont but their stuff,
    Suarez International had a service to fit red dots to OEM glock slides, you just send them in.

    Not sure of the cost. Probably spendy.. As all his rebranded gear is.

    Do they drill and tap that action or what?

    Most outfits mill out the slide in the shape of your MRDS, then drill and tap appropriate holes. Most joints charge about $125-150 for the milling and then Cerakote above that. Right now I am just using an interface plate that uses my rear sight dovetail. It is essentially just a friction fit. I'd sure like to have two holes drilled and tapped for a direct interface...without spending $175-$200 per gun. This is for USPSA Carry Optics, not self defense.

    The reason I wonder about just drilling and tapping is that Lone Wolf offers such a service for just $40 each gun, but does NOT do it for OEM slides. Only for their SS slides.

    Any reason why the OEM Glock steel couldn't handle the forces on those threads?

    Okay, I just had a chat session with Luke over at Lone Wolf. The official reason they do not drill and tap OEM slides, but instead "melt" and then drill into more interior steel is this:

    They have to get past the ultra-hard tenifer to have steel that can more easily tap.

    He did tell me that he would talk to the machinist next week (after Thanksgiving) and see if they would do it for a larger charge. He also told me that the front and rear walls of slide steel that are created by a melt job help distribute some of the forces of recoil. Otherwise, all of the recoil force would be borne by the screws, themselves.

    This all makes a lot of sense, but I'm not happy about paying a lot of money after spending so much for the sight!

    One more update. LW just told me the custom shop is willing to drill and tap an OEM slide for $10 extra. So $50 to drill and tap 2 holes. But about $185 to mill the slide and Cerakote it.

    I already put $30 into buying the dovetail interface plate I'm using right now.

    Decisions...

    The ones I linked to will mill the slide to fit the RDS, then drill/tap to actually mount the RDS

    I've got the G19 Gen 4. Great CC
    Now that Glock released the MOS model, it's on my buy list

    The RDS ends up barely below the slide top if at all, on the MOS. And the sight also isn't cradled by the meat of the slide like it would be if milled exactly for your chosen RDS.

    Watching, to learn how others are making this work.

    I've got a G20, a Delta Point Pro, and I ordered the MOS 4 plate set from the Glock store. I hope this works.
