If you can find someone who would do that...seems like a no-brainer.May just have to trade the 357mag gp for one.
GP-100's in .357 Magnum are fantastic guns, but there must be 3 million of them out there. WAIT! Ruger just made 20,000 more of them while I typed. There must be 3,020,000 of them out there!
Point being... easy to replace a GP in .357.
