Congrats on pulling the trigger. That 22 mag will be humming with that 9 1/2 barrel. As for as the holster watch around gunshows and LGS for odd ball sized holsters. I found one for mine at a yard sale. Fits the gun fine the barrel sticks out about a 1/2 in. It was a homemade holster like some kids make at school in leather shop. Thiry years later it still serving well, I hope that kid got an A+ in shop.
