Ok guys, bear with me. It's been close to 6 months since I last shot my Ruger SR1911 5" .45ACP. During the shoot, I expereinced no problems whatsoever with FTF, loading, edjecting, getting hung up, etc. Recently, I purchased some new Wilson Combat magazines and upon racking the slide to load ammo in the chamber, the slide gets stuck. This isn't happening without the magazine in the pistol. I have dis and reassembled the pistol numerious times with no positive results. Any feedback as to how I can correct this problem would be appreciated.
