Step 7 on the trigger removal tutorial reads as follows: Step 7: While the manual safety catch spring is pulled up, use a small punch or other tool to push the manual safety engagement lever out of the frame. Is some degree of force required here, or am I pushing on the wrong part. It looks like the two ends, of the lever/axle/pin that needs to be removed, are the same two ends that are pulled down to engage the manual safety. Correct? I'm a little shy about wacking that area with a hammer and punch. Also, is there information available on removing the firing pin? The process is referred to frequently, but either I'm using the wrong search word combination, or I'm being unusually dense (this one gets my vote), and can't find the instructions. Thanks!!
