I carry a KEL-TEC p-11 9mm .It is smaller than a 2" 38 and it holds 11 rounds .You can get a pocket clip so it can be carryed in a pocket or in the waistband without a holster. In my area cops isued a S&W 9mm carry them off duty because the S&W hi-cap mags fit the gun. It is rated for some use of +p ammo ,I carry REM goldensaber 124gr +p ammo.
