"For a red-dot light base compatible with the Smith & Wesson 5906, several options are available on the market. Here's what you might consider:

"Custom Mounts: Companies like BME Mounts have been known to create custom mounts for the 5906 that can fit micro reflex sights. These mounts typically replace the rear sight and can be made to fit specific red dot sights like the Burris FastFire II.
Dovetail Mounts: Some manufacturers offer dovetail mounts that work with the 5906's existing sight system. For instance, Dawson Precision offers sights, but not explicitly red dot bases, though you might find third-party solutions that use similar principles.

"EGW (Evolution Gun Works): They have mounts that are compatible with S&W models, specifically mentioning that certain 1911 fixed sight mounts could work with the 5906 due to the similar sight cut. Look for something like the #49530 for the RMR.

"Aftermarket Solutions: On platforms like eBay, there are listings for micro red dot sight mount bases for S&W pistols, including the SD40VE, which might fit with some minor modifications or might directly work with the 5906's dovetail.

"Gunsmithing: If you're looking for a more tailored fit, some opt for gunsmith services to mill the slide for a direct red dot installation. This is more permanent but ensures a perfect fit and potentially better accuracy.

"Remember, when installing any new sight or mount, it's essential to ensure the fit is correct to avoid any issues with zeroing or stability. Some mounts might require slight modifications or professional fitting due to variations in slide cuts among individual firearms.

"If you decide to proceed, consider checking the compatibility of any red dot you plan to use with these bases since not all red dots will fit all mounts without adapter plates or specific screws. Also, bear in mind that some of these solutions might require a bit of patience as lead times could be significant."
