As more sub compact size red dot sights are entering the market, there are also lot of confusion on what is compatible with what.
In this quick to read guide, we breakdown the spec differences between RMRcc and RMSc, and categorize all available products so you don't end up buying something, wait for shipping, then realize it doesn't fit.

Aftermarket Adapter Plates
If you have been searching online for adapter plates for your particular slide mod, then you have probably came across CHWPS, DPP, EGW and many other manufacturers making aftermarket slide adapter plates for various optics.
Gun manufacturers usually do a good job by including these adapter plates when you purchase a optic ready pistol, and some requires the user to buy them separately.
As more sub compact pistols are entering the market, slides with RMSc footprint seems to be the most popular.
Custom Slide Milling Service
There are tons of custom milling shops around the country to mount an specific optic to the slide.
It provides a much tighter tolerance to hold the optic in the cut so it doesn't shift or move.
If you would like to mill your non-optic ready Sig P365, Glock 42, 43, 48, Springfield Hellcat and other slim slide handguns, please check out these services below:
