Sean's Review of Strike Industries MP 9mm/.40 Full Size 6 Round Extended Magazine Plate

This mod can be used with the M&P 9/40 C with minimal modification.

To do this;

Remove backstrap key.

Use hand file -
~ 3/5" across the interior of the backstrap key.
~ 1/8" deep, with sloping/tapering toward the magwell. ( less slope for more clearance and speed ).

Good buy. It would be awesome if I did not have to mod my gun but, I cannot be disappointed when the company does not manufacture parts for my stuff. For that, 4 stars. Small engineering change and too easy to fix.
Having said all of that. I hope this was useful and yes. I just bought another one!
Pros:
  • Price, ergonomics, capacity, ease of install on magazine
Cons:
  • Not designed for compact but easily could be, extension not flush with rear of grip
Best Used for:
  • Duty, sport
Would Recommend: Yes
