I use loctite 262 on my Glocks. Even though it is red itís a medium/high strength. Iíve never had a problem breaking it loose with small screws without using heat. Iíve also never had it work loose like I have using blue.
Be sure to clean the screws of grease/oil well. I go finger tight and my fingers arenít as strong as some. Iíve never put a torque wrench on a Glock but if I did Iíd probably follow the same recommendations as scope rings.
You know, as Iím typing this, I remember I had to request different screws from Vortex to fit the Glock MOS. They sent them for free but you may want to contact your red dot mfg and see if they recommend different screws.
