I don't care for lasers... The flex in the guide rod makes sense. I'd already replaced the connector with a 3.5lb, and added Lightning Strike striker and safety plunger. The trigger pull is (IMO) alot better and smoother than stock.The guide rod was the last modification I was looking to do.
I have the Zev tech connector and spring kit in my Model 35. Model 22 has the ghost or lightning I cannot remember 3.5#
