1998-2000 S&W 4046 .40S&W
2000-2008 Glock 22 .40S&W gen3
2008-2012 Glock 31 357SIG gen3
2012-???? Glock 31 357SIG gen4
I will probably retire with the gen4 Glock 31. No plans on changing anything. The department is still issued gen3 Glock 31s. I ordered four gen4 Glock 31s in February for long term testing. So I am testing the gen4 along with 3 other officers.
I'm not sure when the department switched to the S&W 4046 (probably whenever they first came out), before that, they were carrying S&W .357 Magnum revolvers.
