Well, I just took dad's Taurus .22 that I got for him probably over fifteen years ago. Cleaned up and smoothed and polished everything up. The center pins/struts for the mainspring and trigger rebound spring were pretty rough and every time you pulled the trigger you could feel every turn ring on them! I found all the parts surprisingly hard (which is good) so I used diamond files, stones, and sandpaper rather than files, which would just barely cut (and dull my files). Deburred here and there and got everything smooth. By golly, it's not that bad of a gun, just needed TLC. The DA pull is now tolerably good, the SA hammer pull is ok. Not great, but better than it was before.
Now again, this one is fifteen-twenty years old (and it needed work...) and apparently quality control has only gone down since then.
