And I have to ask, is there a trick to getting the trigger return spring on the pin that the trigger hinges on? I did actually got it on, but it was a PITA. I am sure there has to be a right way to do it. |

A small short pin, called a slave pin helps a lot. It fits into the trigger pin hole and holds that end of the spring in place as you put the trigger, slide lock and locking lub into the frame. Then you push the trigger pin through and it pushes the slave pin out the right side of the frame and the hoop in the trigger spring slides off the slave pin onto the trigger pin. Another way is to use a 1/8" sharp shouldered punch inserted from the left right side of the frame, work the spring onto the punch and then insert the trigger pin from the left side of the frame and push the punch back out of the frame. Usually, if you've got a nice sharp cornered punch the spring will slide off the punch and onto the trigger pin. It's one of those jobs that is "the more you do it, the easier it gets." Good luck |

Good luck Thats more or less how I got it on, I used a slave pin to align everything, and used a thin punch as a spring hook to get it on the actual pin. I thought, there has to be a right way to do this, besides how I did it

| I bought over the past several months, I have purchased four LEO Trade-in M&P 1.0. Three of the four had defective triggers where the trigger safety springs failed. I put Apex triggers in them and also in a couple of SD40 pistols. This last pistol I bought was a .357 SIG last month, it looked like new. The trigger safety was functional but I still replaced it with an Apex. I guess I finally mastered the install as I had it completed in five minutes. I have learned to hate working on S&W pistols, going way back to an armor's class where we built 59 series pistols. |
So... I find comfort in the fact that if Trump has to work so hard to go to Heaven, then there is a shit load of Democrats that have no f-cking chance to go anywhere but HELL. Sometimes it is entirely appropriate to kill a fly with a sledge-hammer.

I had success once I gave in and went and got my reading glasses  I just assumed that Smith would have designed an easier way to do it, and I would of course do it the hard way. Sounds like its just a PITA. |

| I use one of the frame pins as a slave pin. After I drop the trigger bar and spring in I hold it muzzle down with the trigger bar held up with my finger out of the frame so the trigger spring moves very close to position. Slide the frame pin (either locking block or sear housing pin) through the frame and spring to hold everything, then push the trigger pin through. Requires a slight wiggle but I found it much easier than using a short slave pin that does not keep everything aligned with the frame holes. Took me a few tries but I can swap out a trigger bar and spring in minutes now. |
