What do you think?.. : I recently bought a Springfield Range Officer. I like it alot as it is, but as I am I can't leave well enough alone. So.. I shopped at Wilson Combat for some upgraded "drop-in" parts. Among them A reduced power hammer spring to above all things lighten the trigger pull. When I got the spring side by side to the hammer spring that came in the Range Officer I noticed the Wilson Combat spring was about 5mm longer than the other one. I tried to install it and was unable to get the mainspring housing flush with magwell to effectively insert the mainspring housing pin... I called Wilson Combat and was informed that this is not unusual and that I should compress the spring I bought from them for a period of time to "condition" it before inserting it. I did so leaving the spring compressed in a vice for hours. Then I tried again with the same results I had initially: mainspring housing just a hair off from fitting. So?.. I cut one single revolution off the spring and wha-la. it fits. I re-assembled the gun and tested everything out numerous times.. It works, but I am totally frustrated that I had to modify a Wilson Combat spring to get it to fit in my gun.. should I have done this?
