Jaycee,
Not sure how many rounds you have put through your R9, but today I broke 100. Prior to this, I had several malfunctions. Today, I put approximately 75 rounds through mine with no malfunctions. I shot GD 124 Gr, Win 115 Gr and some old Uzi ammo I had that was just plain hardball. Not sure what happened, but after my first 100 rounds, something got lapped in and made the difference.
Hope you have the same good luck with yours.
