Alright, weird question here. Can I take a current (Gen 3?) G35 slide and mount it on a Gen 4 G22 frame? The reason I ask is that I would like the barrel length of the G35 with the reversable magazine release option of the Gen 4 G22 (I am a lefty). I am sort of guessing you cannot do this as the recoil system was changed on the Gen 4 but gotta ask.
