The Optic Cut and threaded shroud is what sold me on the M&P 5.7


If you don't want the optic cut or threaded shroud/barrel, the FN Five-seveN is probably more up your alley.

The 5.7x28 cartridge is far more capable than the other pistol cartridges. It benefits from a red dot. You can shoot it at 50 yd - 100 yd quite easily. Even the best and thinnest iron sights are going to cover too much of the target beyond 50 yd. I shoot my PS90 SBR at 100 yd with the MC-10-80 unmagnified. The SS195 ballistics has enough velocity for 200-225 yd but that's out of a 10.4" to 16" barrel.
