Regarding the cocking handle, just don't put your fingers inside the loop when closing, instead use your palm on the outside of the loop and there is little chance of the lever breaking.
There is a very specific reason that this model was replaced by the model 130: valve lock. Valve lock is when the gun is over pumped to the point that the valve will not open when the hammer hits it. The only solution is to disassemble the gun and manually force open the exhaust valve. At Crosman, when a gun is "repaired" without anything being wrong with it that is assigned as a design failure. So, the designers (Rudy Merz at the time) were under management pressure to fix the "faulty" design.
