I am looking into getting a 1911 that has an alloy frame. I am usually carrying my TRS with me most of the time. I was looking into something a little lighter. Looking online at some lowers, I noticed Caspian has a Titanium lower receiver. Anyone have the skinny on them? How do they hold up? Are they stronger than the aluminum lowers? Expected life of the Titanium? Wanna kill these ads? We can help!
