We had a thread a while back on mounting a red dot on a 228 Link but it never resolved to a definitive answer, and there clearly could be issues with a folded slide and pinned breach block.

In general, is there a practical, not aesthetic, opinion on milling DA/SA Sig slides for an RMR?

My eyesight isn't getting any better, and at some point, an RMR may be the best way for me to go. I am a dedicated DA/SA guy, love my Sigs, and have a small pile of them. I don't want to have to move to striker guns or a new design to accommodate an RMR if I can have my current crop of Sigs converted.

Thoughts?

If you want to do it, no reasons not to. Just not on a folded slide, though.

Google images shows pics of P226 slides milled for RMR's so it looks like it's possible.

There's also this, which I know nothing about other than it exists. Maybe try one of these before milling the slide?

Parker Mountain Machine offers the service. I picked up a 226 RX caliber exchange kit so I can leave the originals alone

I’m not sure the exact question in this. If it’s a milled slide then it’s fine. I’ve had quite a few done. PMM and L&M are the two I trust. Thousands of rounds no issue. If you don't want to mill your original you can get the exchange kit and L&M will make it take an RMR and not the pathetic sig optic.

Thanks everyone. That mounting plate looks like an interesting option. I could get one of those and decide if I even like the RMR system without buggering up a slide, and then mill some if it made sense.

There's no way I would mill my German 228, but I have a nondescript 229 that is a good candidate for an RMR.

I appreciate all the help.

Hey Artie - If you get the adapter plate above can you post up a review please.

I definitely want to get a red dot at some point and adding one to a 226 with the adapter seems attractive.

Cheers~

EGW makes an RMR adapter plate.

You push out the rear sight, and push in their plate to the slide's dovetail channel. Then you mount the RDS to the plate. Bob's your uncle.

You can do this on an older carbon steel folded slide too -- no milling involved.

Don't like it? Push the adapter plate back out and put your rear sight back in.

A bunch of folks in this thread don't seem to know that not all SIG slides are the same. Milled stainless steel slides are not the same as older folded carbon steel slides. Mill the former, don't mill the later. And then of course if you're in CA - if the slide has a loaded chamber indicator - that might bone you too.

The rear sight mounted ones suck. Only way to say it. First they put the optic higher than it needs to be and second you can't have backup iron sights. For play, have fun. For serious, forget it. And exactly who do you think on this thread doesn't know the difference between a milled and folded slide?

I didn't want to name names, but apparently it's not you. Yes, clearly it's going to sit higher, but the question in the OP was "is there a practical, not aesthetic, opinion on milling DA/SA Sig slides for an RMR?"

*not to mention that as I said, it's not destructive and doesn't require you to risk your slide just to find out you don't like shooting with an RDS. I thought all that had already been stated?

"Practical" is subjective to your needs.
