The Casket Magazine Spectre HC 9mm

Getting his hands onto a pistol that I am sure our Ian from Forgotten Weapons would enjoy having, Tim from Military Arms Channel has posted up a video of his personal Sites Spectre HC 9mm handgun. The handgun features a novel (at the time) quad stack magazine which fit 30 rounds in a less than a 10″ package. 50 round magazines were also offered, but are extremely rare and expensive today.

No longer made (a victim of the previous US “assualt weapon ban), the Sites Spectre is a design that was well ahead of its time. First, my favorite feature is that the handgun is 100% completely and totally ambidextrous. All functions (except ejection) are mirrored on both sides of the gun.

For design aficionados, Tim takes the time to completely field-strip the Spectre. The action is direct blow-back featuring a separate striker block. It also features a dual recoil spring assembly. The magazine splits the round into two separate stacks.

Interestingly, it also features a striker-fired design that can be “de-cocked” using another lever. While not “second strike” capable (which would been just uber-awesome-sauce-cool), the decocker on makes the pull longer and heavier like a double-action hammer.

Despite the nifty features, the magazine caused some issues during shooting. Still, its a fantastic design that when the magazine works, was likely a formidable weapon. Just think of the gun fun with the 50 round casket mags and a full-auto sear!

      Your comments are patently awesome!

        It’s Daniel Watters, what else can you expect but awesome information.

    A Finnish Suomi M31 magazine called. It said “That’s cool, but it’s been done before”.

      Not to mention with how many were made, they can still be regularly had in NOS condition for about $100. I buy them a few times a year.

    Woo, I like it: if putting the mag outside the grip, might as well add more width/capacity. Within reason of course, and assuming the mag could be matured, gotten to run with only maybe 1.5x the failure rate of a double stack.

    I didn’t realize how trim they are, really pleasant, good to see in a vid. Completely ambidextrous; bleh, extra parts.

    imagine if by some amazing coincidence the cooling vents in the forearm had been M-LOK compatible.
