Conversion units.

[SIGSHR]

Jonathan Arthur Ciener has closed after 40 years, CZ has discontinued their Kadet unit. I have gotten a lot of use out of my Ciener units, regret they never made one for S&Ws. Excellent way to train a new shooter, they get familiar
with a CF handgun while learning to shoot with 22s, when they transition to CF the feel of the pistol is the same. And during the ammo shortages I fired 22 exclusively.

I think Ciener created the first affordable conversion but there is so much competition these days I'm not surprised they finally went out of business.
