390: it’s an iconic and beautiful design. Seriously, if Colt wants to remake the 1903 in 2022 or so, I’d happily buy one in. The early 20th century also saw the advent of pocket-sized semi-automatic pistols such as the Colt 1903. Revolvers remained, and remain, popular choices even to this day for their reliability and thanks to the fact that they can be fired from within a pocket if you don’t have time to draw. The 20th century saw a lot of innovation in the realm of pocket pistols. As time wears on, it seems, people have the ability to get a lot more reliable pocket pistols. Still, I’d much rather have a cut-down Colt Navy from the 1840s than a duckfoot pistol from a century prior to that.
Of course, black powder and percussion caps were prone to things like falling out of place, getting damp on a rainy day, and so on. By the 1840s, there were cap and ball revolvers that had barrels as short as an inch or two, making them true pocket guns in the modern sense of the word. I certainly would not want to carry one today, but they are, at least conceptually, the precursor to the modern pocket gun.Īs firearms technology advanced, so did pocket pistols. While they were a lot less concealable than modern pocket pistols or, for example, a dagger, a duckfoot pistol was a way for a person to have several shots, fired from a short barrel, that was more or less useful at extremely short ranges. Some of them had as many as four barrels. Then, there were models of duckfoot pistols that were flintlocks. Something like a pocket pistol has been in civilian hands since the early modern period. Best First Focal Plane (FFP) Scopes for 2022.Taxonomic recommendations at the subfamilial, generic, and subgeneric levels are provided. A model is introduced to describe how heterochronic changes in ontogeny may explain the great breadth of morphological diversification within the superfamily. Cladistic analysis of morphological characters used in previous studies supports biochemical evidence allying Microdipodops with Dipodomys. Based on available karyotypic data, the main direction of chromosomal evolution in the Heteromyidae appears to be toward increasing chromosome number. Protein differentiation has occurred at heterogeneous rates among these major lineages. The extant heteromyids comprise three main lineages (including six genera) that diverged during the Eocene: (1) subfamily Perognathinae (Chaetodipus and Perognathus) (2) subfamily Dipodomyinae (Dipodomys and Microdipodops) and (3) subfamily Heteromyinae (Liomys and Heteromys). Nevertheless, most lines of evidence indicate that the families Heteromyidae and Geomyidae are distinct, monophyletic lineages. These moieties, although recognizable on biochemical criteria, become particularly difficult to distinguish when paleontological data are considered.
Extant geomyoids are divisible into two groups: (1) the Geomyidae, all members of which are fossorial, and (2) the Heteromyidae, whose members display an adaptive continuum from bipedal, xeric-adapted forms to scansorial, mesic-adapted forms. Geomyoid rodents, autochthonous in North America, experienced major evolutionary diversification in the Mio-Pliocene coincident with the development of the Madro-Tertiary Geoflora and the climatic trend toward increasing aridity and coolness. The rodent superfamily Geomyoidea is an old, undoubtedly monophyletic lineage having only obscure affinities with other rodent groups.
