It can but requires a set procedure that is easy to do but difficult to explain.

What I do is pull back the trigger and zip tie it back, then lift up the rear end of the sear about 3mm using a sharp instrument.......then whilst holding it up insert a small screwdriver from the side ( in between sear and cylinder),to wedge the sear out of the way of the piston.
It is easier to do than it was to explain.
