Anthony, this is about as rare as hens teeth in the current market Sir. I would check on large gun and accessory sites like (6)un (8)roker and Armslist as discontinued and hard to find firearms and accessories show up for sale by private individuals and small shops. Just replace (6) & (8) with G & B.

NO ETA on availability. Unlikely to come soon due to Manufacturer focusing on higher demand products. CHECK G(un)B(broker). They have A LOT of Taurus 22BR PT22 available right now. I hope this helps!
