I have not shot the Chippa , but I have held one , and the GSG is by far a better weapon. The looks and feel are far better than the Chippa in my opinion. The GSG 1911 I have cost about 359.00 , that is close to what a conversion cost.
We are at the 110 round mark with the GSG 1911 , and as stated above only one failure to go completely to battery in the first 50 rounds. It will not be cleaned untill I have another failure of some sort. Only CCI's have been used to this point.
The only thing I would complain about now is the grip safety , it has a lil to much spring , you have to grip it tightly.
I'm sure that grip safety is by design... Don't want that massive .22 jumping out of your hand with a loose grip now...
