Get the Gen 2 4.35"m shoot the hell out of it ,,,,then some more then think about swapping parts or not. I have a Gen1 in 40 and a Pro Gen 1 5". It has the A-pex Competition KIit in it and a 1-1- barre;. Sold my original Gen 1 in 9MM to a friend for his daughter. The guns run trouble free and are as accurate as most can shoot. Get the Gen 2m great gun with some improvements over the original.
