I have "three-and-a-half" .22LR handguns. The three "whole" guns are Smith & Wessons, two no-dash 617s and a Model 22A-1 Talo Edition.
The "half" is an Advantage Arms rimfire target conversion kit I can use on my S&W and Kimber 1911s. I don't have a photo of the kit handy but here are my two S&W 1911s.
Fortunately, I always kept a good supply of reloading components and 22LR ammo on hand so the shortage hasn't affected my shooting at all - I haven't bought any since before the shortage and still have 5,800+ rounds left, mostly CCI MiniMags.
