Wasn't there a rumor that we were going to see some of these with a 4.1' barrel? One or two of the sponsors said that was in the works or was something that might happen eventually? Sure would be nice to be able to own one with the real barrel!
I believe they were originally issued to Israeli airplane flight agents (or whatever they were called) their small size made them concealable and their small caliber made them less likely to do damage to the plane, or passengers. Interesting firearm and if they ever make a 4.1' Canadian version I would probably buy it if the price was right!
