Magazine Extensions

If you have a S&W M&P 9c (Compact), you know it comes with two 12 round standard capacity magazines -
one with a finger rest base plate and one with a flat base.

Smith & Wesson will send you a FREE replacement Finger Rest magazine base plate if you call them and ask nicely.

Sorry, this does not include the 10 round California low capacity magazines.

Many think a full-sized M&P 17 round standard capacity makes a fine extra carry magazine. It fits in the 9c.

They're about $15 plus s/h, see

and they make them for other guns, too.

Therefore, according to Math, zero is negative one.
