I loaded 5 rounds in the mag with the slide back. I racked the slide by hand and then fired. Nothing. I pulled the slide back and there were Two rounds basically stuck on each other.
I can't recall 100% that this is exactly what happened. Anyway, I could not clear this malfunction and had to ask the range officer to do it for me just to be safe.
He cleared the malfunction and I chambered a round. After the first shot the gun then didnt chamber the next round. He asked if I was new to shooting and could be limp wristing. I told him I was relatively new but never had this issue before.
For 2 rounds to stack on each other, most likely, the mag was not seated....there just isn't room for anything else really, but I didn't see it.
I'm embarrassed for the shooting community that lack of lube on a rental gun was blamed on you.
It could have been broken too. Rental guns get rode hard and put away dry. I wouldn't blame yourself, or the gun, unless adding lube didn't help.
To the magazine point....Mag replacement especially in 1911's is highly related to the guns not running and people looking for a "quick fix." Quick is often not a great fix, unless you are adding lube. So, I would say....determine why the ng mag is ng. What is the issue?
