I was looking around and came across Blackhawk holster, it looks the same as uncle mikes and the same price. For Blackhawk it's a size 4, it;s actually made for a .22 or .25. When i first put it in it was kind of tight but I let it sit in it for a couple hours and now fits like a glove. Just get the holster that's made for a .22 and you should be fine.
