I really have to wonder how many RG-10's WestKentucky has owned or used.
Like RC, I spent a lot of time trying to repair those guns when I worked for a dealer who didn't believe in sending back defective guns. Certainly, one would not condemn all S&W's or Colts or Rugers because of one lemon, but the whole RG product line was made to sell around or under $10 retail. The shop paid $6, and I was once told the distributor paid $3 so I suspect the manufacturing cost was under a dollar, if that.
Sorry, but those guns were poorly made of inferior materials, and wholly unreliable. I had barrel liners come out, loading gates blow off, hammers and triggers break, frames crack, etc., and that was just from firing a few rounds.
Yes, I am sure that some worked OK, at least for a while, but there is no way one is worth repairing or wasting time on.
