Not a great fitment for 22/45 lite. - Volquartsen Firearms Ruger MK IV Accurizing Kit w/No Trigger

These are quality parts, however they don't all fit the 22/45 lite. I was able to use most including the hammer, sear, and spacers. It would not function properly once I intalled the whole kit, so I had to use the oe disconnector and sear spring. The trigger is alot smoother now, but not as good as advertised since I couldn't use the whole kit.
