I wanted to let the forum know that this combination was possible on the PPQ SC and the journey it took to get there. I am a fan of the SC and know some folks are standoffish on it because of the newly designed dual spring striker system. I like the size, weight, balance, feel, the soft way it shoots, the 15 rd mag and that wonderful PPQ trigger. The pistol has such a nice feel for a 15 rd, 3 inch barrel sub compact. In close to 1000 rounds I have had ZERO problems with the weapon.
I am also a huge fan of Red Dots. My 64 year old eyes just are not what they used to be and a young Navy Seal friend suggested I try Reflex Red Dots. Boy was he right! HUGE difference in my shooting....exponential. My Q5 Match with Trijicon Red Dot is simply the best, most accurate striker fired pistol I have ever shot. And I have shot over 20 different striker fired weapons in the last two years. Sigs, H&K’s, S&W’s, Springfield’s, Berretta’s, Glock’s....you name it. Anyway, I have a custom PPS M2 with a Shield RMS with Bill Springer trigger work that I had Mark Housel in North Carolina mount the Shield Red Dot long before Walther made it a “thing” with their own release. It’s a great single stack and easily concealable. I was hoping the PPQ SC could replace it so I could have a much larger Mag capacity....buuuuut it did not have the ability to mount a Red Dot so off to Mark Housel it went.
Hats off to Mark and his patience and design skill! The dual spring striker system leaves very little metal to work with to mount the Shield. Mark designed a special plate with tapered sides that is mounted to the slide and milled into the rear sight well. The Shield mounts to that plate. It is a truly elegant design and Mark was also able to “co-sight” the piece using the Shield’s rear sight notch and a higher front sight blade. The weapon looks like a factory design....not some bolted 3rd party add on.
Likes:
Lightweight, size, 15rds, ergonomics, low muzzle flip and softer shooter, Red Dot Accuracy, co-witness sights, PPQ trigger, and the gun handles any ammo I throw at it and LOVES my 1000 fps plated bullet reloads that I do the majority of my practice shooting with.
Disadvantages:
Shield RMSc must be removed to change the battery unlike the normal Shield RMS that has a pop out tray. (But heck, my expensive Trijicon on my Q5 Match ALSO has to be removed to change the battery so not really a big disadvantage).
Conclusion:
I like the PPQ SC and recommend it for those who want a smaller concealed Walther but don’t want to give up magazine size and that fabulous PPQ trigger. I have had zero issues with the dual spring striker system and in fact, the gun shoots softer and has less muzzle flip (I believe) because of it. I know pistols are like cars, and everyone has differences on what is right for them. But mix a PPQ SC with a Shield Red Dot and I believe you have a very nice setup.
Mark Housel can be contacted at his Website:
https://www.landmprecisiongunworks.com/ or by phone: (510) 396-0849. For total price contact Mark directly. I was a "one-off" design so your price will be cheaper.
I bought the RMSc sight directly from Shield:
https://www.shieldpsd.com/shop-2/rmsc-reflex-mini-sight-compact-4moa. Including shipping from the UK and exchange rate....it was Approx $320 (Americans do not pay the VAT Tax). Took about 10 days to arrive. I believe Brownells and some other vendors are carrying it now, but probably at a bit higher cost.
