Ruger SR22 decocker-only

[zaitcev]

I noticed just now that safety on SR22 is backwards (like Beretta, perhaps). Since the gun is DA/SA, is there a way make it decoker-only? It can be done on Beretta, but it's not as trivial as removing a detent. Beretta kit adds a spring that returns the lever to the fire position. So, how about the same for SR22? I'm unable to find anything with just the web search, but I hope someone heard something.
