If you have been searching online for adapter plates for your particular slide mod, then you have probably come across CHWPS, DPP, EGW, and many other mounting hardware for various optics.

Gun manufacturers usually do a good job by including these adapter plates when you purchase a optic ready pistol, and some require the user to buy them separately.

As more sub compact pistols are entering the market, slides with RMSc seem to be the most popular.


Custom Slide Milling Service

There are tons of custom milling shops around the country to mount an specific RMRcc or RMSc 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:
