Help Please: RMR not fitting Glock Slide

[ducatiti]

So they gave you a new slide?

With PWS, can I ask for something to compensate me somehow if they can't do anything? I really don't know anything about the company.

[ducatiti]

I just heard back from PWS. Per their QC, the lugs are slightly wide as I have mentioned above. They won't be able to make any modifications or provide a replacement.

I'm basically screwed paying $300 for an unused RMR slide I can't use (for it's intended purpose).

Any other suggestions?

Send both your SLIDE and RMR to Jagerworks. They have an actual machine shop and can at least shave the lugs so your RMR fits.

Jagerworks had my slide prior to PWS. They did not want to touch it.

Then you should contact the seller for relief. They have an obligation to sell you something that works. Even if they didn't know it was defective before selling it to you. I think a partial refund is reasonable and thats what I would offer if I were the seller.

If you can't get any relief there, you can shave the posts yourself with a Dremel and drum sanding bit. Shave the outside of both posts so you can split the resulting misalignment of screws across two posts instead of one.

Once you've confirmed that everything fits, then send it back to Jagerworks for whatever work you wanted done.

At this point I think your only options are

a) somehow make it fit
b) put a cover plate on it and shoot with iron sights. It will be relatively simple to make a cover plate fit. You can probably just file the plate a bit and snap it right over the posts.
c) sell it at a deep discount with full disclosure of the issue. I’d offer you $50 for the stripped slide or $100 with sights and internals.

isn't PWS fault to make the bad cut?so why they don't offer any warranty work??

[Litespeeds]

With the OP's luck, those slides were probably blemished or 2nd hand slides that were sold at a discount and not covered under any warranty. I would call this a lesson learned as it wasn't meant for you to install an RMR on a Glock. Save the RMR for something nicer.

It's only .15 off.... might be time for the BFH.

I think it is about .15 mm off if I'm reading the caliper correctly. That is less than .006 of an inch off.

One alternative may be to mill off the raised threaded bosses, fill,re-drill and re-tap the mounting holes in the slide if needed and then drill the mounting area to install the two small front dowels RMR's sights can accommodate and use them to locate/position the sight, with the threaded screws just used to clamp the RMR to the slide.

If the sight cut is machined tight enough you may not even need the dowels. Using a longer screw to mount the sight as you no longer would have the bosses around the thread might allow for more misalignment and you may not even need to fill/redrill/retap the slide if the remaining thread depth is sufficient. Many, many, RMR sights are mounted without threaded bosses and use locating pins in front instead.

Another alternative is modify the sight slightly; .006 ain't much.

A third option might be to see if either an ATOM or Glock MOS sight base pattern can be milled into the slide and use their mounts to install the RMR.

I don't know where you are located but perhaps you could talk to a local gunsmith/machinist with some practical problem solving ability such as Randall at AR15barrels or some of the other gunsmiths on this site that post in the Gunsmithing sub-forum here.

Note. Don’t buy pws. They won’t warranty major defects. Minor blemish sure as 2nd. But what if any major feature is off. Should get scrapped not sold

[Monkeywrench]

If you run out of options and are looking at being SOL consider using emery cloth to work those posts. That little bit (.08mm per side) would sure be easy to screw up with a powered tool.

Sorry I dont have an answer for you. Im just surprised a large manufacturer like PWS wont stand behind their own work. I could understand if you somehow did something to it but they admitted its their fault but refuse to address or rectify it. Honestly, Ive always liked their handguards and want to use one for a build, but now Im deff staying away from them. Good luck. Hope you get this sorted out.

Cutting 101

Cut the cheapest part to replace......

Why do you need the plate to use an RMR on the slide?

Because a Glock slide is not wide enough to fully seal against the gasket on bottom of RMR.
