to often?, not often enough?

I just got done with my complete cleaning of my Ruger LCR revolver in 9mm, I do this every 6 months. Now I clean after shooting, I clean the barrrel and wipe down the gun but thats it for basic after shooting cleaning. now every six months even tho I don't take the gun apart other than the grip but every six month I have been removing the grip and oiling the mainspring and even tho I haven't shot 1000rds i also oil the pivot pin area, I also put oil down in the cylinder latch area and down in the slot where the hand is, I clean and oil under the ejector. I have done this since I got my LCR back in December 2015, does anyone else do this type of cleaning? should I do it more often?, less often? I haven't had any problems with my gun, this is a habit I have got into. I also while I'm at it do the same with my rifles and shotguns too. thanks
