I am no gunsmith, but have opened my 1911 up and replaced/fitted a trigger. I also have a Springfield loaded model 1911 .45, made in 2013-2014. Can you please explain what happened in better detail, also I see no pictures, but am on the forum via my android phone, although I usually can see peoples pictures. With what basic information you are giving, I would guess it probably not a magazine issue, as a magazine issue would likely only cause failures to feed and things like that, but how far does the slide come back when this happens? Also how old is the pistol and approximately how many rds through it? Also how often do you clean it and do you clean it well?
