Need Technical Help

I recently bought a Beretta px4 storm sub 9mm. As I was cleaning it for the second time, I somehow was able to pull the slide pin completely out of the gun. As I was carefully trying to re-insert the pin, the "lock pin" that holds the slide pin popped out. Can someone tell me how to re-insert this lock pin, or is this a micro repair that only special tools and/or a gun smith can repair? BTW, if you have never owned or fired this gun, you're missing out. It's a great gun to shoot and conceal carry!

Are you talking about takedown pin/lever from a PX4 subcompact? If so, carefully inspect where the takedown pin goes(i.e. the hole from which you pulled it out of). If you notice, a spring is angled in the whole and you must, or should reinsert the pin's cutout at that angle, about a 1/4 turn up or so and push it in. To field strip, rack the slide to the rear, rotate the takedown lever down, gently pull out 2 clicks, but do not take the takedown pin all the way from the frame and take off the slide. Assemble in the same manner but reverse. You kinda have me confused over "lock pin" and "slide pin"?

I'm sure you already got this resolved but I just got the same problem and found this thread. Here's what you have to do. The retention clip doesn't go around the pin but sits beside it with it's long side fitting into two flat spots on the pin. Put the clip into it's spot with the top in place and lower round part not fitting in. Then force the pin in and get the clip to fit in the middle flat spot. Then while pushing in on the pin, take a thin screwdriver and help the lower part slip into place. After that the clip should be in place and then you can use the directions in the manual to take it apart. I sure hope this helps someone else as I have maybe 6 hours of messing with this thing.

Did a takedown at the range and fully removed the lever, unfortunately. I have obviously lost or broken something. I have the lever, but only a very short semi-circular clip. I've looked at the Beretta schematics and don't see the 'retention clip' you refer to. What does it look like, and where can I get it. Thanks.
