I working on a pps43 trunion and the spec is 1.1xx" tube with a chamfer depth of .25" and a chamfer of 1.062". I guess I need to find my dig. camra and take some photos of a tec9 reciver I have and the feed ramp. I guess what Im looking for is should the tip of the bullet (9mm) be just above the ramp or even with. muttman

For those of you using the sten mags, here's the inside view of a sten MKII (at least from the magwell forward) which shows mag to barrel and round to feed ramp/cone relationship.

thanks moleman, that filles in the blanks. a budy is letting me (grope) study his tec9 befour I put a finish on it. ** just a side note the suomi mags that I have will just start to fit in the mag well**.
this is what I was refering to with the extractor easy to replace easy to make.
next is the feed ramp a close to the pps43 trunnion print that is on the web.
then we have the striker and firing pin
hope this helps sombody ealse to build a home brew. muttman

No Hope For Me
pretty straight in. also note the sten mags center the round were a pps 43 mag feed from each side. breach to mag distances will be more critical on the pps mags. the good news is with the 7.62x25 is it,s a bottle neck design so the hole vs bullet clearances are much greater than a 9mm or other straight wall round.
the ejector on the TEC 9 is really simple looking I see. is it made from thin spring steel entirely ? is there a spring pushing it in? I need to get a close up lok at one of these. I want some thing easly made reliable and serviceable.
still waiting on the sarco barrels and VZ ejector. I hope they shiped quickly like they said. Anyone delt with them?

Sarco is ok. I suppose they are like any other large company. Just because they say they have it doesn't mean that once you get your stuff from them some things won't be marked as "out of stock". I ordered a mauser barrel from them along with some other parts this past winter. The operator said the barrel was in stock, but it wasn't. The only customer service issue I've had from them was a new m1 garand barrel that would swallow a field guage and have room left over. They took it back and sent me another one without any questions.

it would be nice to have a tracking number shipping confermation anynything?? my pilots thaat I orderd two days ago got here already.

They told me 7-10 business days and I think I had my stuff just shy of the two week mark. Ups only took a few days to deliver, so the other week and a half was on them. That could be why they didn't have a barrel left in stock for me.

the extractor is just a wire rod thea has a bend in it for the "spring" and a set screw holdes in in place. kind of like a 1911 extractor except the bend is for the spring and not how tight it holds the round for ejection.
