Hi,
I am a new member.
I own a USP .40 caliber full size. I wanted to know if the USP 9mm threaded barrel, 4.56 inches would fit? I believe the model number is USP-T 219069.
There will be a lot of play in the slide because the .40 barrel is larger, but why? Buy one that fits and works. Don't forget that you will also need a complete recoil spring assembly (RSA) if you plan to shoot suppressed.
