I have a "wristbreaker" and it is easy to open in spite of a dozen things happening at once:

Single trigger, auto-reset safety, assisted opening, ejector gun.

I hadn't even considered the idea that the gun was called wrist breaker because it hurt the owners wrist. I thought they were called that because there is hardly any wood in the gun after in letting and they are often proofed for 1-1/8 or 1-1/4 ounce. If any model of gun deserves a broken wrist from recoil, it is this patent.

I'll post some pics eventually.
