Glock

Glock plus 2 magazine extensions fits all double stack Glock 9mm, .40 and .357SIG. Will not fit single stack mags like the Glock 42 and 43.

This is the plus 2 extended baseplate ONLY and does not include the Glock OEM PLUS 2 MAGAZINE EXTENSION INSERT; this will only work reliably with both the baseplate and insert used together.  Please make sure you purchase both if you are upgrading an existing standard capacity magazine.

Glock plus 2 extensions add 2 rounds to 9mm magazines and 1 round to .40 and .357 SIG magazines.
