At 2013 SHOT we had reviewed the Phalanx. John Rassias was back this year and I had a chance to stop by his booth for a quick chat. The product has gotten some updates since then which definitely increase the versatility.
John has put together a system that protects against gun grabs and accidental discharges while also offering a very rapid draw, from really any position, standing or seated, and without telegraphing the draw.
The system is highly modular and can be configured to work as a duty holster, concealable (though this is going to print more heavily), surface mountable (think bed frame or nightstand), thigh panel, or as a strapless shoulder holster.
There are two core models that are “auto-loading” in the sense that drawing will chamber a round (there are some people that carry without a round in the chamber, and of course the “Israeli Carry” method), and a “loaded” model. In both cases, the gun in the holster is “out of battery”, one to a smaller degree than the other.
The Phalanx also provides a relatively secure storage method with use of a locking pin to will prevent the firearm from being extracted from the holster (not to the determined thief, but think small kids, etc).
Overall I think it is a pretty interesting design, and I personally like the idea of a solid mount holster that I could attach to a bed frame, etc. It is pretty bulky so depending on your carry preference, concealment may be an issue.
