Not only is it an amazing range gun, the compact model can make for a nice carry gun. The coonan is bigger than a standard 1911. Due to the size, it does use some custom parts.
Here is a list of similar parts, the coonan has 19 parts that are direct replacements: Hammer & Pin Hammer Strut & Pin Sear, & Pin Sear Spring Recoil Spring Disconnector & Pin Thumb Safety Plunger Tube, Pins (Front & Rear), and Spring Barrel Bushing Recoil Plug Grip Screws Grip Bushings
Also there are 5 parts that require some modification: Firing Pin Stop Grip Safety Grips Mag Recoil Spring Tube
So yes it can be customized to however you like, even better you can use a lot of off the shelf 1911 parts. You can see i switched my magazine release to an ambi one, from cylinder and slide.
