ok, so the sigma IS a glock clone... s&w settled a lawsuit out of court and had to make changes in the design and pay glock a huge punative damage settlement. they did not recieve a licensing agreement however.
the m&p is a direct desendant of the 2nd generation sigma, the model produced AFTER the design changes mandated by the settlement.
so the m&p is no more a glock clone that the glock is a clone of the hk vp70 (12 years before the glock) or the browning hipower.
a polymer firearm isnt unique.... remmington started making the nylon 66 in 1959 (11years before the vp70)....
and i do know guns
