Top 20 M&P Magazine Extension
If you like your concealed carry gun, you won’t need to find a compromise between capacity and size with a magazine extension.
Why do we need Base Plate Magazine Extension M&P?
Magazine extension allows small firearms to feel bigger and enhance strong hand grip while adding both length and magazine capacity.

This Extension Base Pad converts the 7+1 to 8+1, but it doesn’t fit the 6+1 as the spring is not the same as the 7+1. If the spring bends or binds up the extra round won’t fit.
