I have disassemble my gun to deburr and polish parts. Everything went great until i went to reassemble. the problem i am having is with the take down spring and level. with the trigger housing installed in the frame and the take down spring in place, i am able to install the take down bar but it is very loose when in position. the spring acts as if it is getting stuck and not returning to its original position. i have tried tweaking the spring slightly to see if i am able to get it to the position. i am at a lose right now. any advice would be greatly appriecated.
