OK, here's the latest update -

STI discontinued the original 22 kits. Primary reason was they couldn't get them as fast as they wanted them.

STI has made a new deal with a new supplier and a better 22 top end will be out soon, but it's more expensive.

I figured I wasn't going to see any 22 kits until next year, and they would be the new ones.

To my surprise, STI just shipped me a bunch more of the original conversion kits that everyone seemed to like - so I have them now.

I doubt they will last long - $507 SRP for the 1911 kit with one mag. $540 for the 2011 Kit.
