Hello there, I purchased this bare Colt Combat Elite XSE frame from an estate sale. The frame serial# dates to 2014. The first pic show's how I received it. Obviously the frame has been cut for a beavertail but I can't figure out what the radius is and I'm not smart enough to figure out how to measure the radius. The last pic shows a new Colt Competition beavertail installed on the frame. I'm speculating that the Colt beavertail off the Competition Model has a 250 degree radius, (but not sure) so the one cut for the frame is smaller? maybe 220? Can someone more knowledgeable than me identify the radius?
