They really are funny little carbines. I got mine, with the threaded barrel, when Turner's had a Grand Opening sale for around $400...yup, we can have threaded barrels in CA
The most surprising thing was the weight for a pistol caliber carbine. The recoil was a bit more than I expected, but it was mostly due to the weight of the reciprocating breech block. The largest advantage of adding a muzzle break is the added weight at the end of the barrel dampening barrel whip. A really nice ad-on is the factory free float foreend...if they ever offer it as a separate item
Volquartsen will soon be introducing a drop-in trigger assembly
I was going to mention the Midwest handguard the other day then got busy with something else and forgot. It is a pricey option ($160) but I will likely end up going that path. Results will be posted when I do!Midwest Industries makes an M-LOK, free-floated hand guard for the Ruger PCC 9:

My PCC 9 has functioned perfectly, thus far. Some are surprised by the weight of the carbine. Its weight is very comparable to that of a 16" barreled AR carbine with polymer furniture. The Ruger PCC 9 is not quite 5 ounces heavier that the Ruger AR 556. I find the balance of the carbine to be very good.
Being a blow-back design, there is more recoil impulse than many expect. I actually find it comparable to shooting an AR in .223 Rem/5.56x45 mm. I also have a Hi-Point 995TS 9 mm pistol caliber carbine with the same length barrel as that of the Ruger. The Hi-Point is a little lighter. The recoil impulse is just about the same.
Did you put a muzzle brake or flash hider on yours?. If so where did you get one??
I looked for one but the price is lame compared to one for an AR.

Taccom makes 9 mm compensator/muzzle brakes in two different lengths that are said to work well on the Ruger PCC 9 (I have not tried one):
M-Carbo also sells one:
