I recently purchased a G29sf. I love this weapon. It feels great in my hand, and I believe I like it more than any hangun I own. HOWEVER, I am not really confident in the factory guiderod / spring assemby. I hate to say it, but it looks very weak. I am hoping that I can tap into some of your knowlege here on the Ten Ring. First, What should I replace it with? Stainless or tungsten? Second, I intend to shoot Winchester Silvertips. Should I go 19 lbs or stay stock? Finally ....... where is the best place to find this replacement part? Thanks guys Wanna kill these ads? We can help!
