I have a 64-3 in 38 spl. the cylinder was cut to allow for moon clips to shoot 9mm, would they have to hone the cylinder as well? Is it safe to shoot 9mm and 38 spl. from the same cylinder?

Yes, the chambers have to be reamed with a 9mm chamber reamer.
.38 Spl chambers are .380".
9MM chambers are tapered .380" at the mouth to .391" at the head.

Be aware that once reamed, shooting .38 Spl in it is not advised.

I guess he talks about the cases getting stuck, but they will fire, steel cases bulge but brass does not, not sure why that is, but he says you can still fire both. I guess it is my understanding that nothing has to be done to the barrel correct?

Yup, you've got a very cool gun there, but I'd consider it dedicated to 9mm shooting. That's not a hardship, by any stretch.

(O.k...it would be a hardship if you happen to be an IDPA shooter as the gun can't be used in either revolver division. Moon clips = no SSR, 9mm = no ESR)

ok, with that being said, I had a couple 9mm that sounded quiet, not sure it was the same cylinder but it didnt do it every time, just sounded funny, I was using Winchester 115 gr. FMJ, any thoughts on this?

Could be a light charge, I guess. The factories aren't perfect, but they're pretty close. I assume you checked for bullets stuck in the barrel?

Funky WW white box ammo most likely.

Or you have a head cold and your ears are stopped up.
