I believe a least one state agency has dropped the Glock in 357 & gone with the M&P in 357.
New Mexico State PoliceI have fired one. It had some significant blast like all 357 SIG caliber guns, but felt recoil was pretty mild. It was more pleasant to shoot than the Glock 31, and is likely more durable. I believe a least one state agency has dropped the Glock in 357 & gone with the M&P in 357.
