Using a Threaded Barrel inside a Full Length Slide

[Blaster229]

My 320 has a 4.7 threaded barrel in a 3.9 slide.
I want to get a full length slide to use and it requires a 4.7 barrel.
Of course it won't fit with the thread protector, and I would prefer not have to spend money on a regular, non threaded 4.7 barrel.

So, would the .8 worth of threads be ok "inside" the end of the new slide?

IDK, it sounds like tolerance stacking to me, at least. If you never plan on adding a can, it might be worth trying, but I don't see it being workable, let alone optimal.

I’ve found most tilting barrels pistols have a bit of “rub” on the top of the barrel when the slide comes back during recoil.

If the 320 does this, I’d be concerned about rubbing on the threads like a super coarse file and damaging them (and potentially the slide…)

Yeah. This is what I was thinking and really have no idea. Guess I could check for some wear on my new 3.9 standard barrel with that slide.
