these are highly stylish, and are very nicely made. if you already own a cocker and are using a mag as a backup, this is especially nice since it uses cocker barrels. when using it without the backspin feature, i find it performs on par with anyothe rmag. with the backspin, it has an impressive flat shot with more range.
I encountered only one major problem when i switched over, and that was a the gun woudl not fire until i shimmed the back of the rail and grip. an interestign problem that i so far have found no cause for. be sure to note that no powerfeed plug coems with the body. my onyl gripe with the actual design is the powerfeed position. we did nptice it was a little harder to clean after a ball break as well.
this is a gimmick. it will do what it says if you are willing to invest the time in it. I have a hard time reccomending it though, the price is very high and with the headaches it causes, you may find yourself goign back tot he old body. For those of us with a cocker or cocker threaded barrels lyign around, it is an alright investment, but something to think carefully about before buying. it does look good though.
