Beeman P17 pops open

well is the cross pin the hammer latch still in place, I see no way that the pistol could come open if the hammer is not damage and the cross pin is there

oh I do see there could be 1 other thing the hammer spring could be broken

if you look at this HW40 diagram parts 420-504-505 would have to be in place and undamaged
