If purchasing 1 and only 1 suppressor, and a G17, and a .223 AR-15 with removable (Ciener, AACK) .22 conversion kit are fair game what suppressor would you guys recommend? I am hearing of some folks putting 9mm cans onto their .22--does this apply also to .223? So, would a 9mm can be suitable to shoot on both the G17 as well as the AR, in both .223 and .22 configurations? Or is the best bet to just buy a .223 can and use it on the AR only, but in both .223 and .22 configs? Thanks!
