Hi Gary, there are lots of 1911 22LR Conversion kits available that would work. They are expensive (almost as much as a dedicated 22LR 1911). I would check out some prices and if they are within 70% of a dedicated gun, I would just get the entire pistol. I would verify operation with Advantage Arms as they state "This kit will not work on 9mm Springfield and 9mm Rock Island" for both their target ans standard model kits. this may or may not have changed. ---- : advantagearms.com/mm5/merchant.mvc?Screen=PROD&Store_Code=AASOS&Product_Code=1911SD&Category_Code=

advantage arm standard conversion kit on my RIA 9mm ultra fs the only issue I have with it is that it is somewhat ammo picky mine works great with all CCI ammo, Winchester M22 ammo, Remington DB and thunderbolts. It will not work with Federal 22lr ammo link below advantagearms.com/mm5/merchant.mvc?Screen=CTGY&Store_Code=AASOS&Category_Code=1911

Hi Gary, Unfortunately there is not a conversion kit for this yet.
