Dead end handguns designs

[BB57]

How about the Dardick revolvers that used a triangular shaped cartridge,
a tround? I remember reading about them as a kid in a very early
Guns and Ammo magazine. Late 50’s early 60’s? Willyboy

I always wondered how the Dardick revolvers would have been defined post GCA 1968. They had a three slot revolving cylinder/feed mechanism on top of a double stack magazine.

The cuts in the “cylinder” were V shaped to accommodate two sides of the plastic cased “tround” and the case, supported by the top strap formed the outer wall of the “chamber”.

——

I remember the concept was partly revisited in the late 1980s in proposed H&K G11 assault rifle design using a square profile combustible round with the bullet encased in the propellant, using a plastic device at the front to keep the bullet centered during the combustion process. The primer was also combustible although I think it used thin copper that basically melted when the cartridge fired.

The rifle used a rotating breechblock similar to the Dardick cylinder. The idea was to reduce the ammunition weight and increase magazine capacity, much like the Darrick cartridge.

The G11 was also a dead end. As I recall West Germany planned to adopt it, but the Soviet Union then came apart and East and West Germany reunited, and between lack of need and lack of funds the plans to adopt the G11 died.

Recall seeing pictures of a "tround", it was actually a plastic adaptor to hold a 38 Special case. Dardick also designed a carbine mechanism for it.
Revolvers such as the Rast Gasser, the M1873 and M1892 French revolvers, the M1895 Nagant, the Tokarev pistols were not designed for the commercial market hence they inspired no imitators or further development.
Design features that have not caught on are the magazine ahead of the trigger guard-Broomhandle, Bergman-Bayard M1910, e.g. The rotating barrel-Beretta Cougar, Obregon from Mexico, Steyr-Hahn M1912. Loading from a stripper clip-Broomhandle, Steyr-Hahn.

Any semiauto pistol that loads from a stripper clip into an internal magazine is a dead end design. Internal pistol magazines, either in the grip or in the action like the C96 evolved into separate steel magazines. A big improvement.

The original Tround had an all-plastic case. Somewhere I have a few. There was also an industrial Tround of a considerably larger size used for hard rock drilling. I also have an example of one of those.

I believe the Savage 1907's 10 round double stack magazine "qualifies" as the pioneer of modern high capacity magazines; no other earlier pistol design that I know of utilized a detachable double column magazine.

That's correct.

Additionally, I believe it was one of the first. if not the first, striker fired handgun.

1917 below. Wish I still had it. Pics of the striker bar as well.

I'm not certain but seem to recall from reading that the Maxim and Vickers mach9ne guns used toggle actions.

SIG DAK

Double Action Kellerman (not Keller-man), an entirely useless long DA stroke and option for a heavier weight short reset follow up pull. The strangest thing ever and the last thing I want to think about when pressed to use it (no pun intended).
