The retail snap guns hit the pins in the lock then the needle returns to it original position. The coathanger guns just snap and stay in the original position pretty much.
eg. ---------------------- <<< snap pick while in original position
- < pick while being depressed

then the needle will return to itss original position. so my question is - how can the neddle hit the pins but keep in the original position and still open the lock. what should happen is the top pins will bounce but the bottom pins will remain in the same position becuase they are sitting on the neddle of the coat hanger gun. if this is confusing just ask me and il tryu to explain it better. + great site plenty of useful information and not many idiots.
