Is the pin the holds the trigger group to the receiver designed to be removed? Mine seems like it can slide out to the left but not the right. Is it supposed to be permanently fixed? May just be a bad peen on the right side if it is supposed to be fixed.
 
It is only meant to be removed in one direction. It can however be inserted from either side. Push the small wire spring inward and tap that end of the pin into the grip housing. Then pull it the rest of the way out.

I think they are simply peened to keep them in, but not difficult to break them loose. One of my rifles will allow the pin to walk out. It needs to be peened but I'm not hammering on it.
I'd ask Tor at D-K.
 
I was thinking the same thing. It’s certainly not falling out and I’m not keen on tinkering with it. Lots of times trying to re-peen weakens what edge flaring you have.

I’m just relieved that it’s not an uncommon thing. Probably just a by product of early stamped guns.

The pin I posted above is supposed to be the only removable pin relative to the trigger group assembly. It not only holds the buttstock but the rear of the trigger pistol grip group. If the part you are referring to is in the front of the trigger group, that is supposed IMG_2167.jpegto be a rivet and non removable, Posting a picture would have made it clearer.
 
My bad… I forgot the buttstock pin also held the rear of the trigger group. My apologies for the miscommunication.

I am the "happy" owner of a BD44, purchased in 2010 from the Canadian importer.
The gun is a stunning reproduction of the original one, I have a dewat MP43 hanging on the wall and you cannot
tell the difference, I would be surprised if the clones were not stamped on the original molds from WWII.
The internals are a different story, everything broke or simply wore out, left the gun non functional, and sadly no help from our importers or SSD.
Thanks to the internet, Gunbroker and Ebay I managed to source all NOS parts from WWII out of several European countries, installed them and the gun runs flawless now.
Anyway, to make a long story short, the pins for the sear, hammer , trigger etc. are pushed in and peened, they came out with a bit of effort.
Putting them back in I did not peen them, just made sure the ends were clean and free of oil and put a drop of red locktite on them and tapped them into place.
Have put a lot of rounds through it and they are holding up well.
Should I ever want to take them out a bit of heat with a small butane torch will soften the locktite real fast.
 
Hello Hatrick 😉 Take a look at someone on eBay who is offering an original pin for the trigger group. If you look at the pictures you can see that the pins are slightly grained. If you press them together very lightly from both sides with a vice the pin comes apart on both sides and then it holds permanently. I've done it a few times with my Dittrich😁It should actually be attached in such a way that it can no longer be removed

Roos... from what I understand and I think what you are saying is that the pin is pressed from both sides and the edges of both ends flare (bend) out a bit and hold the pin permanently in place. I think my pin was probably not pressed evenly as one side has a much larger raised lip than the side that wants to slide through the receiver so that one side is basically flush with the side of the receiver.

For now I'm trying M1-Garands trick of a couple of drops of Locktite on both sides.

That is correct. Both sides of the pin should be flared evenly. MP40 series uses these on many parts
