My State LE agency carried Sig P220s for 7 yrs. At one point there was a major issue with Sig blued mags, cracking at the back feed lips. They were all replaced by Sig with SS 7rd mags. The State Trooper SWAT team at one time carried Sig P220s w/ 8rd mags and they had lots of problems. Now have Glocks, sorry to say. We had very good agt qualify rates, very few gun-related issues until all of a sudden we got a new Administrator, a Cop Groupy!, who decided we didn't had enough bullets, because his former groupy clan mimiced the local militray w/ 9mm & 15rds. (Never mind that his old PD, he was the MAyor) had multiple multi-round fail to stops with the Beratta 92F! WEwent to Glock 40 M22s and God Bless America, due the politically degenerative leadership in my old agency, no one has been placed in harms way during the kissass mentality they now have.
