broke my hammer strut.... was looking into cylinder and slide.com. thinking of using this as an opportunity to upgrade. getting a new strut plus a drop in hammer and sear kit. i have heard that all things 1911 need to be fit by a smith... is this true? can I not do this on my own? I would also love to hear of your online parts buying successes and failures as I would rather learn from your mistakes ( no offense ) than from my own!
