Yes, the trigger return spring is no fun without the TRS pliers... yep, there is a specific type of plier for this, shared with the locking lever springs in the G36 and UMP as those are almost as much a PIA.
At the risk of getting lynched, this is exactly how I do mine except I put a piece of tape around the trigger to keep it forward instead of using napkins. I changed my P30 twice yesterday trying the Todd Green Special. Didn't care for it so I changed it back to V1. I can now change the TRS in about the same time as it takes to field strip it and get to the TRS.This isn't as hard as most make it out to be. Make sure your gun is locked down with a vise or heavy books or whatever will just keep your gun from falling over or moving. Have good lighting and have the right tools (1 punch, long needle nose pliers, napkins). Take a look at the TRS and it's positioning. Take a picture to remember how the legs are seated. Drive the punch through and get the trigger axel out (right to left). Pull the punch back just enough to get the old TRS out. WARNING ... Old TRS will fly out so be careful. Next, push the trigger all the way forward and stuff a big paper towel or napkins behind it to keep it in the forward position. Now take the new TRS and just place it in there with the pliers with the legs in the right position. You won't get it at first but just aim for the legs to be positioned in the approximate position. No need for perfection because adjustments will need to be made with some patience. Once the legs are positioned correctly you will need to push down with a lot of force to get it in there enough to push the punch back in and drive it through. Not easy but once again be patient and pay attention to the details. Now that you have the TRS locked in place with the punch you are almost done. Slowly pull the punch out from the right side and push the trigger axel through at the same time (left to right) and voila... YOU DID IT! Get the paper towel out from behind the trigger and you are done.
Just wrote these off the top of my head do if I missed anything small please don't kill me. Just try and try until you do it because this "job" isn't the PITA that there talk about. It's nice to be able to test out the feel of a trigger when swapping out all 3 TRSs to see what fits you best. Good luck and if you need more help PM me and I'll be glad to walk you through this again.
Something I found that works well as my 1/16 punch isn't really as long as I would like it to be, once you have knocked the trigger axel pin out most of the way with the punch, use an air needle (like for pumping up basketballs) to finish pushing it out. Gives you a lot more area to work with and is the same diameter as the punch.palutz59 is correct about a long punch of the right diameter. I think this job would be impossible without one and I should have mentioned it earlier.
After having done it without one, I agree! I wish the TRS recommended by Travis at HK would lay there in place, but it won't as the relative angle between the two ends is much greater than my stock TRS and the ones that came with the LEM kit. I realized after comparing them side to side that that was one reason I was having such difficulty. I could get the stock TRS back in much more easily.At the risk of getting lynched, this is exactly how I do mine except I put a piece of tape around the trigger to keep it forward instead of using napkins.

Those of you trying this without a vise is insane. And I hold an X300 in my mouth so I can see down into what I'm doing. There is very little tension on the TRS. Actually my stock V2 TRS in my P30 just lays in the slot. When I pull my punch back out it just lays there, have to go in after it with the needle nose to get it out.
If anyone needing one swapped is in the East Tennessee area, I would be more than happy to swap it out.
That too! :wink:I'm telling y'all. Repeat after me. Vise. Vise. Vise. It's almost impossible without one.
