Looks a lot like the old LAR Grizzly that came out in 50AE shortly after the Desert Eagle released in 50AE.

A buddy of mine bought one and let me shoot it. Kicked like an Army mule. After a mag, I started loosing the feeling in my fingers, I've been diagnosed with Carple Tunnel Syndrome. It's hell getting old.

How does the 50GI compare to the 50AE.
