I would appreciate suggestions for a pocket or waist holster for a S&W Model 629-6 44 Magnum with a 3 inch barrel. Does any manufacturer make a holster to fit this short N frame well?

Milt Sparks will make one, check out the website. I love my 200aw for my 3" 629. They make the PMK for it but I don't know. That's another great model, but the 629 may be too big for it.

I carry my 629-2, 3 " in a Simply Rugged "Sourdough" pancake holster.You won't even know your carrying it.

Simply Rugged Sourdough Pancake +1
Or a Lobo Enhanced Pancake

Call Matt DelFatti, Milt Sparks, or Lobo (he's on this list) and tell them what you think you want, then listen and follow their advice.

This isn't cheap. Never cheap out on your holster and belt.

You must also get a very good belt from the holster manufacturer.

A full setup including belt, holster and mag pouche(s) will run up to $400.00, and well worth it.

I had a hard time finding a thin holster to appendix carry my 629 PC, so I made one. Pretty straightforward. If you don't find what you like, make one!

Looks good what type of material did you use

Thanks! I used a .080 sheet of Kydex.
