Some models have internal cavities along the firing pin that prevent red dot mounting. Please verify whether yours does or not before ordering. See pictures for examples.
Slide internals should be left installed on all models since some parts may require modification.
*Old stamped steel slides with removable firing block CANNOT be cut for optics.
Although most pistols can be milled to accept a red dot, if you have an odd model or are aware that there may be issues then just contact us prior to get confirmation that you do not require special services. By default the rear dovetail will be retained if possible, however, many slides are not large enough and require that the rear dovetail either be removed or relocated. Relocating a dovetail is a separate service available for $50.00
If you need help choosing a red dot or need to know measurements then just contact us.
Generally any model red dot can be used. Templates are maintained for most of the common manufacturers, but it is still a good idea to include your red dot for installation as each slide is fitted to the optic.
