Among the useful bits of information to come out are:
– Yes, it can use a suppressor. Apparently the top strap of the firearm either hides or is a barrel wrench that can be used to remove the existing barrel and screw in new ones, including threaded options. It takes a bit of work, and may not exactly be a field task, but the option is there.
– Yes, those two rods over the barrel are its charging rods… or, at least, one of them is. The other is a "restrike" rod that resets the firing mechanism without actually cycling in a new round, allowing you another shot at that stubborn primer, or an easy way of press-checking the firearm. I still cannot say as though I am terribly keen on putting my fingers that close to the barrel, but I guess we will have to see.
– The gun itself weighs 15.2 ounces, unloaded. Honestly, that seems a bit heavy; the Kel-Tec P-32 masses 6.6 ounces empty, and the PMR-30 weighs in at 13.6 ounces, with the latter shooting more, more-powerful rounds than the ZiP.
– They claim to have revolutionary new safety mechanisms built into the gun, but I honestly do not know enough about current ones, or about what they are talking about, to have a blessed clue.
Anywise, they have made a first draft of the owner/operator manual available online, so that should answer most of the current questions floating around the intertubes.
I still want one. In fact, if they can maintain the $200 price point, I may get one as soon as they roll off the assembly line. There is something about an inexpensive firearm that shoots stupidly-commonly-available ammunition from stupidly-commonly-available magazines and can fit into a purse or cargo pocket that just trips my giggle switch. As Sendarius said, is USFA were to release the designs for that thing on a 3D printer and sell the inner, metal bits themselves, "gun control" would be deader than the proverbial door knob. Hell, as it is, the ZiP is only a few steps away from being a better version of a "blister pack" gun.
In fact, given its name, the way it is presented, its affordability, and a few other nuance-y details, I would almost bet U.S. Firearms was intending this to be a mainline, mainstream, actually-reusable Liberator pistol. I would be lying if I were to say that marketing did not affect me.
