I've been impressed with the accuracy, size, weight, and overall concealability of the M&P Shield, so much so that I'm considering it as my full time CCW weapon, both summer and winter. Since last year's winter carry (M&P40 Pro 5") had a Crimson Trace Lasergrip and Lightguard, along with a melted JPoint micro red dot sight (JPoint has a rear sight built in), I was thinking of milling the slide and adding a JPoint to this winter's CCW M&P40 Shield w/CT Laserguard.

The Shield's slide is .95" wide, while the JPoint measures 1". My question is: In your opinions, does that small step between slide and sight present a problem, would it bug you having a step there?

P.S. This thread is not to be misconstrued as a pulpit for those advocating 9mm over 40S&W, as that decision is up to the individual shooter, nor is it intended to be a discussion on the efficacy of laser sights on defensive pistols. Discussion of MRDS over non-MRDS is welcome, but lets keep it civil. And please, keep it relevant.

The RMR's on both my compact and full size over lap the width of the slide by more than
the .05" your Shield would have. I have never had a problem and never give it a second thought. I hope who ever might machine your slide is sure doing the cut will not cause an
internal problem. Not all slides are capable of being cut for a red dot.
Sounds like a great idea, the dot removes any handicap from having a short sight radius.

One could always try one of the rear sight adapter plates before cutting the slide, it would only be a little taller with the adapter. $40 is worth seeing if you'll even like it before making cuts.

Thanks, but the Doctor doesn't have a built in rear "iron" sight, so I'd need extra milling and a rear sight, unless I really trusted the MRDS (which I don't.)

Like I said I have no first hand experience with the Docter, I'm just throwing ideas out there you may not have considered so here's more.

David Bowie has been known to mill and fill a line of the back of a MRDS to help with aligning the front sight in the event the optic fails (I'm sure others could do this also). The sight picture is a kind of dot on top of post. I don't think he has experience with the Docter or the Shield though.

I hope you get this done. If you do you will achieve pioneer status.

My Shields are fantastic carry guns but my old eyes have a lot of mileage on them. Good luck and please keep us updated on your progress.:welcome:

Edit: Is it true the J-Point will die if it gets wet?



This one is set up with both a rear sight and the milled line.

"The entire electronics package of the JPoint® is in an epoxy sealed chip with no exposed wiring. This results in improved recoil tolerance and water resistance. The JPoint® will tolerate submersion in water with no damage. The battery may short out momentarily, but it will not be damaged. The Docter has exposed wires and is therefore much more sensitive to water intrusion."

No, but exposed wiring in the Doctor is suceptable to water intrusion. I read a post by David Bowie stating prefers a melted JPoint for his EDC and SWAT firearms, because they're bright, low mass, and reliable (among other things.)

I know this is a old thread but were you able to mil the slide and mount the JPoint? This would be my idea of the perfect carry gun.

None of the red dot sights currently available are as narrow as the Shield's slide, so they'll stick out the sides (much like the tadpole being choked out in the picture above, just to a lesser extent). I might do it anyway, eventually, but even at 57 I'm still getting sub-5" groups at 25 yards with my M&P40 Shield. I also compete using my EDC M&P40 Shield, regularly besting capable shooters with full size firearms.

Contact David. He's done a number of Shields. Every combo you might imagine.
