DIY 38 Super conversion FTF problem

[boisepaw]

I put a RIA 38 Super barrel in a TISAS 9mm 1911. Everything seemed to fit fine but…

1) Consistent FTF issues even with a variety of magazines and ammo.
2) If I hand feed an individual round, some will chamber okay and some not.
3) If a round does chamber, it fires just fine but shots are pretty wild…like 7” group from 25 yards with the group being 7 or 8 inches to the right of my point of aim.

NOTE: the same barrel dropped into a RIA 9mm 1911 functioned flawlessly.

What do I check next?

Funny you should say that. I’m sitting here with the 1986 one volume version. I don’t know what is added by going to two volumes…

It looks as though Kuhnhausen did some slight expansion of the original…perhaps not much…and made that Volume 1 after creating entirely new and updated material for what he called Volume 2.

Remove the barrel in the misfeeding, scatter gunning set up. Look for hard strikes on the sides of the barrel hood extension. Also check for barrel spring and barrel bump. Do the barrel timing tests.
