Would it be worth obtaining a 10.5"-11.5" barrel for the Colt Model 6951?

Which barrel lengths are you talking about?
You mention both 10.5-11.5 & 5.5-6.5?
What advantage?
Major loss of velocity, major increase in muzzle blast & noise. Increased wear & tear, because of the increased pressure from the gas port being closer to the chamber, unless you put an adjustable gas block on it.
If you want a toy go for it.

Triple up on hearing protection especially in 5.56! PCC's not so much.
A 10.5" barrel or 11.5" barrel would still be a step up over the 4.25"- 4.7" barrels of most service-size pistols. An added FRT could come close to equating SMG performance. A binary trigger wouldn't raise too many eyebrows. Bear in mind this PPC has no forward assist (as if the original 5.56/.223 ever needed one). The 16.1" barrel provides great ballistics, but indoors the longer barrel can become cumbersome.
House clearing would be easier, and the muzzle blast would be limited by the birdcage (A2-type) flash hider.
This is the reasoning behind my proposition.

I saw a gun vid a few years ago showing 7-8" barrel maximizes velocity on most common 9mm rounds. Shorter and longer barrels than that slows the bullet. At least that's what the video demonstrated. Classic Firearms iirc. Maybe not what you asked, but it is why I chose the SP5 over the SP5K when I made that purchase. And that assumes max velocity is a goal...
Ballistics By the Inch tends to differ with you. (These are from real guns, not test barrels.)

8" is a really good length for a 9mm barrel
Better than the 6" I had on mine originally.

I have a 10.5" AR pistol in 9mm. Totally fun and worth it. Suppresses great.
Someone, a co-worker I like but don't fully trust about citing current law, mentioned I could turn it into an SBR without a stamp.

Not me, Classic Firearms. Velocities measured by chronograph, not gelatin depth measurement. 2 different things.

Just get an short barreled upper to swap.

Standard Uzi is a 10” barrel and a MP5 is right around 9”.
Go for it.
Suppressed will be great at that length

i have an ar15 pistol with the 7 in barrel, i have seen a 5 in barrel for it but that might be to short. mines also in 7.62x39. i have an ak47 and 4 sks's, so when i bought my ar's, full size and pistol, i got them in 7.62 so i didnt have to buy a different ammo. cool toy, no other use really.

i have a binary on my AK, its sooo much fun. wanted a forced reset for my AR but dont know if you can still get them or if they are still "legal".
