HYVE Technologies https://hyvetechnologiesbuilder.com/ offers aluminum magazine extensions for the S&W Shield; +2 for the 9mm, +1 for the 40 and 45. I picked up one for the 45. Easy install, and provides the one extra round for the 7 round magazine only. Web site states it will not work on the six round magazine.



So now you have the possibility of a 6 or 7 or 8 round magazine for the pocket cannon.



I carry a 6+1 in a Kydex, and now have the 8 rounder as my spare.
