G Code....
Both G Code and Blackhawk market polymer holsters for S&W J frames.
I like the SERPA CQC holster design. It's safe & you can adjust the holster cant, height, position. You can wear the rig strong side or cross-draw.
The G Code Kydex line comes in different colors & has different choices for the holder; paddle, belt loops, MOLLE, etc.
Blackhawk J frame SERPAs with or w/o the security feature are available in most retail places online.
