380 ACP Seating Challenges. FMJ FP COL?

Mark my problems with the only Rock Island gun I own have been traced to the factory magazine that came with the gun. My only RI so far is a 9mm. When using the factory supplied Mec Gar magazine it was a jam-o-mattic. Switching to Metal Form magazines solved all problems I had with the gun.

I am wanting the Baby Rock. No one around here seems to have one when I have the disposable income to buy one. I got my wife a Browning Black Label 1911 .380. I would probably try to see if the Rock would take the Browning mags. You may also try to see if it will take mags from Kimber, or Sig as well.
 
Good job Mark! Might want to fiddle with that 3rd mag and maybe it too will loosen up. Maybe a slight shot of spay oil.
Thanks Kevin, getting better at disassembling these magazines. Took mag 3 apart for a thorough cleaning, light lube, and worked the follower up and down a few dozen times. It “seems” better, but the proof is in the shooting. Loaded up new rounds last night, including a first use of CFE-P. Will give mag 3 an extensive trial.
