BBQ Boy,
You are awarethat there are differentshims you can use between the butt of the stock and the recoil pad.
I am 5'6" so I removed ALL of them and the Extrema fits megreat now even with a heavy jacket.
The 3 1/2" mags work great for geese and turkeys (glad to have the option available).
ONLYONE down side; Gas guns need thorough cleaning more often than inertia semi-auto's.
