I am trying to locate a 9mm Luger barrel conversion for a 9x18 Police PP. Anyone have any suggestions on where to begin?
Thanks in Advance.

That is still a blowback gun and I would not want to shoot 9mm P in it.

I doubt a barrelmaker would want to take on the liability.

You could rechamber the factory barrel if you just must have the combination. Will the magazine take 9mm P?

I don't recommend it. There was some nitwit on one of the boards "sanding down" 9mm to shoot in a Browning BDA (Beretta) .380.

Y'all be careful, now, you hear?

I have to second Jim Watson's advice. I don't think the PP is a suitable platform for 9x19mm.

I cannot locate the pressure specs for 9mm Ultra. I suspect that CIP has a spec, but I don't know what it is. I don't believe SAAMI has a spec for that load. But if I had to guestimate, I'd say the max pressure of 9mm Ultra is far closer to .380 ACP's 21,500 psi than 9x19mm's 35,000 psi.

As Mr. Watson noted, the PP is a blowback gun, and not a locked breech. The only blowback guns of which I am aware that can handle 9x19mm have far heavier slides and springs than the PP.
