My name is eddie and I'm another idiot who mistakenly took out the middle pin holding the hammer catch in place. LOL
I wrongly thought, "I have Gen 3 Glocks and they have three pins, too. " I did the dumb thing and removed all three pins during my first attempt at taking apart the LCP.
I studied the diagrams and read up on how the # 16 spring orientation went and how hard it is to get it and the #27 hammer catch back in place properly.
I ended up MacGyvering two tools that *might* help someone like me that took out the #31 hammer catch pin by mistake.
Tool #1.) I used a bamboo kebab skewer and fabricated a small pin about 1/16" longer than the hammer catch is wide. A small wooden dowel would work, too.
I placed spring #16 on the left side of the hammer catch with the 90 degree bend in the appropriate hole.
Then I put the bamboo "pin" inside the spring coil and into the hammer catch to sort of hold things together.
Tool #2) The easy one. I stuck an old WD-40 spray straw onto the long end of the #16 spring. The wire has a slight bend in it and will press fit into the straw.
Holding the hammer catch with a good pair of needle-nosed pliers, I eased the catch/spring assembly down into the frame, making sure the WD-40 straw
went down into the mag well area.
Before I began, I had started the #31 pin into the right side of the frame enough that it only just protruded into the interior of the frame.
Holding my mouth right, as my Grandpa used to say, I got the spring/catch into position with the catch pivot hole over the tiny bit of pin.
Seeing how this was about 1am, it took about 10 tries before I got things in place without the catch and spring popping out of the pliers.
But, once it was lined up, I gave the pin a slight tap with a small hammer and Voila'! It was in place.
The bamboo pin pushed on out the left side of the frame and fell on the floor to be found by a bare foot later.
I then easily pulled the spray straw free from the spring.
Using Jocko's small nail through the frame hole trick to hold the catch forward, I then proceeded with installing the frame insert assembly.
The counter-clockwise trigger spring deal got me once before I read here how it is supposed to go. Thanks again, guys!
I see no reason to ever take my LCP this far apart again.
But, if you've read all of this thread you can probably piece together enough info to do it yourself without too much cursing. =)
