I also had a pair (not sequential but close) I purchased in 1999 from a member / dealer but sold them when finances had taken a turn in 2006. I believe one of the features on these 459s was that the pistol would fire with the magazine out, which was part of the FBI specs.

Do your 459s fire with the magazine out ? Naturally, the safety would need to be in the fire position. Can you please affirm this by testing yourpistols with the mags out ? Thank you.
