Fullsize 9mm USP would not eject round with flash suppressor...hmm.
Just took my new fullsize 9mm USP shooting yesterday. Installed a new HK threaded barrel and a flash suppressor. The gun would not eject the rounds with the suprerssor on. As soon as I removed it, the gun fired 107 flawless rounds.
I had the wife with me so I didn't spend any time troubleshooting.
Anyone know what would cause this or had any similar issues?
