I need some help. While taking apart my Shadow everything was going as expected until I removed the assembly that contains the sear,etc. I had no intention of removing the safety detent and tiny spring but I didn't know there is a detent on each side. When I put the pistol down the right side detent fell out but I didn't see a spring come out. I'm almost, but not quite, sure it wasn't in there. Anyone know for sure?
