I bought the 4th gen G17 last week and the RTF2 this week. I have 300rds through the gen 4 without any failures at all, even some my 8 yr old put through it with no problems (I no longer buy limp wristing as an excuse). It was his first time shooting a pistol and he is a trick shooter just like he is with his rifle. He is a natural and makes me look bad, and I am ok with that!!! I put 175 rds through the RTF2 without any failures either. I cant decide which one I like better on the shooting/handling, but I like the looks of the gills. His stance doesnt look good, but since he out shot me, my wife, and my nephew on accuracy I left the stance issues for another day. Hes shooting the 4th gen with the medium backstrap in the pic, it was all he could do to get his fingers around the trigger. But his safety is top notch, notice his finger outside the trigger guard until hes ready.
