Ran 4 more magazines through it after cleaning the gun at the end of the previous outing, overlubing it with CLP, and just spraying a little Rem Oil around the magazine followers.

I used all ball ammo this time in both stock mags, wore gloves and used a firm two-handed grip throughout.

I had no unintentional mag releases and no occurrences of the slide getting stuck part way back.

However, I did have two other failures that were different.

One was the slide did actually lock all the way back with the slide lock engaged and rounds still in the magazine. Thumbs were nowhere near the slide lock lever.

The other was when the trigger clicked on an empty chamber. The slide had cycled normally but no round was picked up.

May have to send it in or just keep "testing" it until it straightens out.

I love how quick this gun gets back on target.
