I just recently bought a brand new STI Trojan in 45acp. I went out and bought a few wilson combat magazines. I have noticed that they do tend to get somewhat stuck when I am trying to insert them so I have to give it a good slap upwards to seat them. Then when I hit the mag release, they drop about an inch and stop so I have to pull them out. Is this normal during the breaking in process or is there something wrong that I need to correct? Thanks this is my first 1911.
