No, 4.6". Thread protector is exactly that...something that protects the threads. Barrel is 4.6" that protrudes past the slide so comps and silencers can be added.

The Sig Sauer website is your friendGot it + thank you! Sorry to be the noob but, just in case anyone was wondering "how could he not get that?" I inferred from this 322 video, where they clearly show the barrel with a thread cover that's not longer than the slide, and then the adapter that adds onto that. I was hoping the 320 Legion was similar - where I could remove the "adapter" and get it back to 3.9 slide length when not needed. Rats!

P322 is completely distinct from the P320 architecture.
P320 XCarry Legion. Scroll down to the Models/Specifications table.
It’s a reasonable question. I’ve only been shooting Sigs for two years but all my friends shoot multiple platforms so I have close resources. I do suggest you study Sig, Glock and S&W websites just to learn. That’s what I did anyway.Thanks for being kind to the noob . I do understand that the 320 and 322 are totally different, I was only thinking that the threaded barrel aspect of the 320 legion was like the 322's removeable one that I referenced. From someone who isn't familiar with threaded barrels and just visually looking at the two videos, it seemed reasonable that the 320's might work the same way, but alas!
A number of .22 caliber threaded threaded semi-auto pistols have a small diameter threaded section with a small wrench to remove it. To this a threaded adapter can be added which allows use of a suppressor. Most .22 target pistols have a bull barrel size which is much larger diameter that a normal .22 semi auto, firearms such as the Walther P22, S&W M&P 22, Ruger SR22, PPK 22 etc have threaded sections that adapters screw to to allow a suppressor to screw onto. The adapter extends the OA length of the outer barrel, but is not the same Inner diameter of the barrel and is Not rifled so actual barrel useable length isn’t increased. On large caliber threaded barrel length is rifled so the larger length is true length. Adding 1/2 inch to barrel length can and most likely will improve accuracy and grouping ver the shorter barreled non threaded version.
