I recently acquired STI Trojan in 40 S&W. This pistol is like new but does not lock open on the last round. The lock open mechanism is not worn and has a crisp edge. I ordered 4 new STI mags but the problem is the same with all of them. I looked through the ejection port while inserting the mag and the lifting tab on the magazine follower goes right by lock open lever. I don't want to start bending this tab on all of the mags. Could I have a defective lock open lever right from factory. I guess I should be asking the factory but maybe someone else has experienced the same problem.
