Just like the title says, I'm looking for a factory rear sight off any of the ruger sr series (sr9, sr9c, sr40, sr40c) pistols. It can even just be the middle plastic piece. I'm looking at getting a part fabricated or modding the factory sight, but I can't put my daily carry piece out of commission. I know you can get them through ruger, but I'm not really wanting to pay 30 bucks for something that's just going to get measured or modded up. Shoot me a pm or email with what you have. Thanks!
