i just saw a video on the silencerco osprey. (
http://www.youtube.com/watch?v=pQfq8ab-nn4&feature=fvsr) it was very quiet and also veery light. tested at an average of 128 db and weighs just 11 ounces. a little bit longer than the gemtech and about $100 dollars more but like i said, very quiet. i dont think you will need a recoil device. the silencer itself will reduce recoil and on a 1911 it would be even less.
