Has anyone had the slide for their .45 M&P milled for a RMR? I recently went to the range and brought my CORE 9mm and my .45. The core with the rmr was so much easier for me to shoot due to my aging eyes.  I wear progressive glasses and they suck for iron sights.
If you have had one who did the work and post a pic or two. Thanks.

I've only had my 2 m&p9's done. L&M precision did mine and they're great. L&M and ATEi set the standard.

I finished up the RMR install on my .45. I first machined a piece of scrap to the width of the M&P slide to practice on since I can not replace the .45 slide if I had messed up on it. I'm happy how it came out.  

You more balls and skills than I do sir, well played.

Is that a PRO back strap from a 9mm? I would like a little more texture to my full size 45 1.0 but I don't want to add any girth to the frame.

Thanks.

Yes it is from my PRO/Core. It is the medium back strap.  

Making that first cut had me a bit nervous even though the RMR fit my  mock up slide perfectly.

Just what I was looking for. Couple questions because I am going with a JPoint or Shiels site. It looks like you incorporated the dovetail into your cut ? Is the machined depth the same as factory dove tail ? Why did you choose to have raised shoulders around the threaded holes ? I was thinking of machining flat so one could use an adapter plate for different sites. Did you have any issue with the striker block being under the new site as opposed to factory rear open site ? Thanks.

The dovetail is for a glock suppressor height rear sight so it is made for that. It's a 74 degree x 250 cutter. Dept of cut was .079.

I added the bosses as I read stores of screws breaking off without them to support the RMR. The RMR would fit tight without them since I fit the cut to the sight but what the heck, I can do it so I did as added insurance. The S&W Core plates have stamped bosses to locate the sights.

I didn't have any issues with the striker block other than the little round cover is a pain in the arse to hold in place while assembling everything. I may make a cover like the Core model has if I get really bored one night.  I machined the RMR cut lower than on the Core models so the cut is flush with the striker block spring retaining plate. It is .135 deep if I remember right.

The hardest part of the project was tapping those holes. That slide is hard and I was worried I would snap a tap off. I used 2 plug plus 1 bottom taps as they dulled quickly.
