If you do how often do you need to clean it ? I cleaned mine today and it was a pain in the drain. I could not get the cylinder pin out to save my life, finally took the ejector rod out and oiled it up a bit and it came out. I cleaned everything up and all the holes that the pin go through. I wonder if those wood grips or the brass need any kind of attention ? Also how often do you clean the barrel, someone told me they never clean their 22 barrels ?
