So on Saturday, I went out to the garage to fit a ambi saftey to my new Clapp Commander and got it stuck. Couldn't remove it and somehow it jammed the sear in place. Took a needle file and filed off the surface of the thumb safety and was able to get it to release the sear and get some play but I still cannot get it to pivot up enough to remove it. Any suggestions? Once I am able to remove it (if I am able to!) I'm putting the original safety back in and leaving it alone!
