barnbwt, I wasn't saying that the design principle of reverse feed is not sound.. I'm saying that two compare it's effectiveness/reliability in two COMPLETELY DIFFERENT weapon platforms is meaningless.
For an 'apples to apples' comparison, the US M60 machine gun took several sound, proven design features from multiple machine guns that had worked well in combat (MG-42, FG-42 via the Lewis gun, etc). However, the end result never really lived up to expectations despite the proven design features that were implemented. Just because a design feature worked well in one weapon system, doesn't mean it automatically works just as well in another, especially in a completely different weapon platform.
Could reverse feed work just as reliably in a pistol as it did with machine guns? Sure, why not? Some company one day might make a reverse feed pistol that matches, or exceeds, the field proven reliability of current Glocks, M&P's, Sig's, etc, with all ammo types. However, stricly IN MY OPINION, the Boberg design is not that pistol. Because of that, and the fact that their are a multitude of reliable, field-proven options, I would never choose to carry one.
