Slide Mounted Red Dots On Small Pistols By Galloway Precision


My EDC CCW is a Sig Sauer P938. I have modified it a bit so I pay attention to any interesting developments with the pistol. Step in Eric Galloway of Galloway Precision. He machined a Sig P938 slide and made a mounting plate for a Shield Sights JPoint MRDS. Add a tall front sight and you have a slide mounted red dot with cowitnessing irons on a SigP938!



The ShieldSights JPoint is the smallest red dot that I know of. When mounted onto a Glock MOS, the factory Glock sights will co-witness with the JPoint.  No other mini red dot sight (MRDS) can claim that. So I see why Eric went with this optic over other red dots.


My only compliant is the front sight does not have the tritium insert like the factory irons. I am not a fan of black blade sights. I prefer some contrast. Even a fiber optic rod would be better than this. But that is merely my personal preference. Im really using the JPoint 99% of the time and the irons are just there as a backup.

And yes, the factory iron sights still co-witness the JPoint.

Here is the M&P Shield compared to my M&P9 CORE. Both have the JPoint red dot. Layed out they do not look that much different.

It is only when you look at them from the top, you can really see how much smaller the Shield is compared to the full size CORE.
