Any holster made for a 39-59 series gun will work for your gun. You need to decide on OWB or IWB. I use my Kramer #3 in IDPA with my M39-2.

There are plenty of holsters made by all makers and can be found easily in local gun shops, pawn shops, gun shows, eBay, etc.

Do a search on eBay using S&W 39 or 59 holster and you will have MANY to choose from.

I seldom pay more than $20.00 for a holster.
