Features 

The 3-inch chamber handles standard 20 GA loads. The pump action is the same reliable Mossberg design used across the 590 line. At 5.25 lbs., it's light enough that the 20 GA recoil is manageable for most shooters. The fixed raptor grip keeps handling consistent.

Owners of the Mossberg 590 Night Stick in 20 GA appreciate its compact dimensions and the Mossberg pump-action's reputation for reliability. The short overall length is the primary draw for home defense use, and most users find the 20 GA recoil manageable.

The pump mechanism draws favorable comments for its simplicity and dependability, with minimal reports of malfunctions. Weight comes up positively too: at 5.25 lbs. it's easy to handle.

The common criticisms are the 5+1 capacity versus competitors and the limited aftermarket parts selection compared to other Mossberg models. Some users want more finish options beyond the standard configurations. The 20 GA is occasionally flagged as producing noticeable recoil for smaller or less experienced shooters despite being lighter than 12 GA, though this is less of a complaint and more a note about expectations.
