kbm - My Sig 220 is a POW, and somehow keeps getting grandfathered in. All of the Bu issued Sig are long gone. There's one other guy in DN HQC who still has a Sig - his is a POW 229.

Philly Patriot - some personally owned Sigs 9mms are still around and grandfathered in. Glock 26s and 19s can be purchased and carried. I've heard of agents being issued 9s under special circumstances - I knew a guy who had a Bu issued Glock 19 because he had hand surgery and was having a hard time qualifying with his issued 23.
