If you decide not to re-barrel, etc., do not remove the firing pin or make any other alteration. Oil it (the inside and the metal...not the wood) up, and store it for someone's future project. The world does not need any more "bubba'ed" guns that have been ruined beyond repair. Your "worn-out" gun may be someone else's treasure.
Sometimes you get what you pay for, sometimes you only pay more for what you get.
Three shots are not a "group"...they are a "few".
If the Bible is the literal, infallible, unerring word of God...where are all those witches I am supposed to kill? (Exodus 22:18)
