On duty my issued Glock 17, and my S&W 642 and/or 638.
Off-duty my G19 and my 642 or 638.
We issue the 124gr +P Gold Dot at work so I tend to use that in all my 9mms, but I also like Winchester Ranger-T.
In my .38s I have carried the Remington LSWCHP for years, and the 110gr DPX, but I recently bought a case of 135gr Gold Dot SB so that is my go-to load for the next few years.
For a recent trip to NJ/NY I carried the 124gr +P Federal EFMJ in my 9mm and wadcutters in my .38 to stay legal under their retarded ammo laws.
In the micro guns I most recently had a KT P32, but I have officially given up on the really tiny guns.
