Well I got my new rear blade for my S&W 27-2. I bought the .160 and watched the videos on utube to get a general idea on how it works..
I got the screw head off and went and bought #4 spanner bit to back out the blade....but the spanner bit broke..So i tried making make shift tools to try and get it out and just can't get anything that small to work...That sucker is in there and I don't know what to do next..Cant get that spanner screw to turn!!!(to back out the blade)those 2 little holes are a b!$%^......
