I have the Thad Rybka leather holster for my 1 and 5/8 mini. Works well and carries 5 reloads (obviously not in real time). However, it will carry 5 22 LR in the pouch, it won't fit 5 22 mags. But it will fit 5 WRFs - which chambered in a 22 mag cylinder.
Yes, reloading this in a fight, they better be really slow zombies.
