Got two new blue steel magazines from a gunsmith friend today. Not sure of brand. They have "Colt 45 Auto" stamped on removeable floor plates. There is no pony stamped on bottom, so I don't believe they are Colt brand. Empty magazines will fit into my 1991A1 with no problem. When magazines are fully loaded, 7 rounds, a great deal of pressure is required to get them to move the last 1/16" or so and "click" in. Will these magazines "wear in" with use?
