^@GJM same type of question with my new M2 compact. Which as you mentioned earlier in thread about the CORE models, also uses the 2.0 plastic base plates for RMR/SRO and other optic types.
Wondering if we could get any general guidance from S&W on avoiding the issue you ran into. So obviously some combo of the following:
* Run the metal
CHPWS 2.0 plate which looks like it's still on backorder. Would this substantially help with the issue of the screws shearing off?
* Torque screws to certain inch-pounds.
* Like you said: rotate mounting screws as maintenance?
Interested to hear where you land on this, kinda' hoping to avoid that issue too. :cool:
