I used to go squirrel hunting using my 6"-barreled S&W M35 as my primary firearm. My cop brother got me a Busheimer black basketweave holster & belt some 30 years ago as a gift, and it fits it just fine. It's more than a bit clunky, and no way could I use it along with a backpack, but it was fine if I was just going out for a few hours. I've got a Swiss milsurp holster for the Beretta, and that might work well with a pack.
It was only $8, and better than I expected for that price. Sometimes I get lucky.
