Great way to increase capacity - Strike Industries Smith / Wesson MP Shield 2 Round Extended Magazine Plate

Used for 8rnd mags so I could use my shield for shooting events that need at least 2 10 rnd mags., higher round count extra mags if needed or for the range. I prefer the 7 rnd with a pinky extension for carry.
Worked great with no problems with 50 plus rounds from each mag and had no problems with there being a large gap from not using the factory gap extension since I have not modified those to fit yet.

Would be great is you do not want 2 more rounds for a 9mm 7 rnd mag and do not want to pay at least $40 bucks for a 8 rnd mag.

The only problem I had with installing the EMP was the base plate getting stuck at an odd angle. Just need a small screw driver or pen to push into place if this happens.

Some people mention tight fitment with the 8 rnd mags. If the EMP is used on an 8 rnd mag you will have to remove material (about .040") from the factory spacer to fit over the back plate that is added with the EMP.

NOTE: Made for 7 round 9mm magazines and 6 round .40 cal magazines. The EMP+2 WILL work on the larger capacity factory magazines but with a noticeable gap between the EMP and pistol grip. The factory spacer will not fit flush with the EMP without slight modification.
