They’ll function flawlessly. I have an OG shield 1.0 thumb safety, a 3.1” plus and 4” shield plus performance center. I run the original shield 1.0 slide on the shield plus frame (13 round frame plus sentimental reasons for the slide) also, I swap my 4” PC slide to the regular plus frame because that frame is cerakoted fde, and I think fde frames look good with black slides lol…both have ran perfectI
can swap them with no issues just wondering if anyone has tried and fired them. I didn’t want to break anything but as far as I can tell they are identical and should work. Again these are 2 shield plus’s. Just one is performance center non-optic and the other is optic ready non performance center. Both are 3.1” barrels.
