With the advent of the 43X/48 and P365 series, we are seeing various red dot sights mounted on the smaller width pistols. I am seeing everything from RMRs to other red dots specifically sized for these smaller width slides being mounted. Thing is, when you factor in Optics Ready slides; the various mounting/adapter plates; and the various red dot mounting footprints - the array of combinations is staggering, and getting more complicated daily. I thought perhaps we could have a thread dedicated to cataloging the various dots and mounting solutions for these smaller pistols; along with the pros and cons of each solution.
