Just picked up a Shield Plus Optics ready. Nice pistol. Ran about 100 rounds through it today and it shoots great. Haven't picked an optic yet. I don't want any plates to raise the optic so Holosun is out. That is what I have on my Glocks and I like it a lot. The 507k required a spacer plate for mounting that will raise the optic up. I'm looking at the Swamp Fox Sentinal in green as I see the green better. Another option would be the Shield RMSc but it only cones in a red dot. Anyone have experience with either of these optics on a Shield Plus?
