I am seeing more and more departments adopting SIGs. The military has adopted the M17 and M18 and many departments have made the leap. It's the ergonomics and modularity. Not everybody drank the Glock Kool Aid. The ground is shifting under Glock and they still have a big share, but are struggling to keep up.
But…..but……but…….Plus Sig has an excellent rifle lineup, makes ammo, etc
