I have a little taurus 450..I've turned the springs a bit and deburred it a bit and the double action trigger is not bad..(it's not in the ron power or jerry miculek class, but it seems ok to me and is my knock-around pickup truck gun anyway)....problem this revolver has always had and more so now maybe is a very light single action pull...it takes very little to set it off, believe me I've seen me do it!....now, I'd like to remove the hammer spur and make it so this thing cannot be manually cocked...to do this..is simply cutting spur off hammer with a file and then dressing up the ugly spot with extra fine files and some stones adequate? any special issues to be aware of before I tear into this thing again? thanks.
