GSG 1911 .22 cal top end slide conversion?

I have been thinking about buying a GSG 1911 .22 cal top end conversion and putting on my MC Operator w/ Ed Brown fire controls, Ambi-saftey & 10-8 trigger and Ed Brown memory grove beavertail, chainlink mainspring housing w/lanyard loop and FBI Firing Pin drilled-out to G.I. Size.

Can anybody give me any feedback on the GSG .22cal top-in slide conversion? I plan on changing out the sights for Novaks adjustable rear and fiber front.

Anybody???
