  • Your right the real 5.7 ammo which is the “Red” box and not the “blue” box which the red is ‘HIGH SPEED’ Is almost only available to M&P the because its armor peircieng…the blue box is the “SPORTING” ammo for civillian use..its much weaker…I give much love to MPA for make a well made heavy duty 5.7 pistol that isint all polymer”plastic” and not charging u over a Thousand dollars.at least i know i can bust out a hard window or fall on or drop the MPA the FnH 5.7 feels so light and delicate i own the mpa 45 mac 10 sidecocker and a mini mac tac 9mm i feel like im holding a Tank and The magazines loaded or empty could be used as a deadly weapon…

  • I searched the web for FiveSeven ammo, scarce, sold out, or very very expensive. How about a chambering in .223 short ~ .22 TCM?
