Kidd,
One thing to keep in mind. If you order a BP frame, you'll also get a V notch rear sight, a blade front sight, and a Bullseye ejector. With the CP frame, you'll get a square notch rear sight, un-tapered front, and a Crescent ejector. At times there has been some BP frames with square notch rear sights but these are aberations and probably won't be repeated. You can mix and match the different ejectors if you so chose.
