Hi guys, so I was installing a new trigger on my P320 when one of the back pins fell out.

From everything I've been able to find out it seems to be a real pain to get in, everything needs to be lined up but since it fell out the path seems to have shifted, I was trying to fiddle with things to get it to line up but it doesn't seem to be working.

I really don't want to completely disassemble the whole thing and rebuild it or go to a armorer if I can avoid it, does anyone have any experience with this or tips to get it back in?

cheers,

Myles

My advice would be, try and line up what needs to line up, by using a punch to move everything into place, then use it like a "slave" pin so you can start the pin and keep everything in place. Hopefully nothing fell out? However my 320 knowledge is a bit "dated". Looks like the small(er) pin (in place) aligns the sear, which is good news, lining up the larger pin may not be that much of an issue? If??? nothing fell out? then all you have/should do is carefully line everything up, there is a small spring that has to be "captured" by that pin, but it should just "pop" into place.
 
At 6:16 you can see how the safety lever pivot pin interacts with the other parts.

A BIG tip for next time ... there is an easy way to avoid that Safety Lever Pin from free-sliding out at the worst possible time:

After removing the Slide and removing the Takedown Lever. Before lifting the FCU out of the grip module - STOP! - first push UP on the Slide Catch Lever (aka slide release or slide catch), feel it "click". Now continue to take out the FCU - Safety Lever Pin is securely retained by the Takedown Safety Arm.
 
Thanks for all the help you guys, I managed to get it all fixed up....what a relief!

I'm glad it worked out!

To be honest, I was a little worried when you mentioned taking it to an "armourer". Guns are pretty simple, basically metal LEGO, lol. Aside from highly skilled work, or work that requires specialized tools, almost everything can be done at home with a little patience and some help from YouTube or a community like this one.
