S&W will be selling the S&W Model 310 NightGuard that chambers .40 S&W and its’ parent cartridge 10mm Auto. Because these are rimless cartridges moon clips will be needed to be used to hold the cartridges together.

This combination of cartridges could be quite beneficial to the budget conscious shooter (ie. every shooter). The cheaper .40 S&W would make a good practice round instead of the hot 10mm which could then be used as the primary carry round.

The revolver features XS Standard Dot Tritium Sights and a Pachmayr grip.

    Has anyone found a great holster for the Nightguard 310?

    I would consider shoulder or belt.

    Since HIghtower asked his holster question back in Aug of 2010, has anyone found a good holster for the S&W M310?
