I have worked with CPE for sometime and they are great guys to deal with. There stuff is nice. I have yet to hear anything bad about anything they carry. I carry a few of there items myself. Not sure really how well the Claw does. I haven't seen one up close or driven one. But my good bud had one not to long ago. Here his is build and take on it.
