Representative implementations of devices and techniques provide a mounting dock to receive and to support an implement (such as a handgun, for example) or an implement holster (such as a handgun holster, for example). The dock includes a substantially planar mount portion having two substantially planar surfaces opposite to each other and a plurality of side edges. The substantially planar mount portion includes an entry edge on a first side edge and a grip portion on a second side edge. The dock includes at least one hard mount base configured to temporarily or permanently couple the hard mount component to a selected surface in a variety of configurations.

Wearable housings are configured in size and shape to be securely attached to a strap, such as a belt, suspender, backpack strap, rifle strap, shoulder bag strap, vest, carrier, or other strap with one or more clasping members. One or more magnets are positioned within the substantially hollow receptacle area(s) of the wearable housing. The magnet(s) have sufficient holding force to securely hold a handgun or other item against the wearable housing for ready access.

A trigger shroud assembly (14) for a small arms weapon (12) is disclosed. The trigger shroud assembly (14) may include a rail mount (22), an accessory body (28) slidably connected to the rail mount, a spring guide (24) disposed between the rail mount and the accessory body, a resilient member (26) arranged about the spring guide, and a starboard side trigger shroud (32) and a port side trigger shroud (34) connected to the accessory body. A belt clip (36) may be disposed on one of the starboard side trigger shroud or the port side trigger shroud. The trigger shroud assembly (14) may include a closed configuration (17) and an open configuration (27). The trigger shroud assembly (14) may include a tactical accessory (47) such as a flashlight. The trigger shroud assembly (14) may be secured to a handgun for inside the waistband carry and to deter inadvertent handgun discharge.

A firearm mounting device securable to a surface and having a magnetic material within a base to attract and secure a firearm to the device in a readily retrievable position. The device includes a channel to receive the slide of a semi-automatic pistol and at least one slide stop disposed within the channel to engage and prevent movement of the slide as a user grips the grip of the pistol and displaces the grip towards the at least one slide stop to chamber a cartridge in the chamber of the pistol. The at least one slide stop engages and prevents movement of the slide while allowing the barrel of the pistol to protrude from under the slide.

A process for making nanoparticles of biocompatible materials is described, wherein an aqueous reaction mixture comprising cerous ion, ethylenediaminedisuccinic acid, an oxidant, water, and optionally citric acid, is provided along with temperature conditions to directly form within the reaction mixture, a stable dispersion of cerium oxide nanoparticles. Biocompatible nanoparticles comprised of cerium oxide, ethylenediaminedisuccinic acid, and optionally citric acid, are described. An increase in catalase-like enzyme activity is demonstrated by cerium oxide nanoparticles prepared with citric acid and ethylenediaminedisuccinic acid.

The present disclosure provides an improved concealed carry clip, that attaches with machine screws to the slide rear cover plate, and which has friction features on the clip to facilitate drawing back the slide with the thumb and index finger. In addition, the cover plate can be equipped with projections that reduce shearing forces on the machine screws. A drilled and tapped replacement cover plate is provided with the improved concealed carry clip. Though the improved concealed carry clips have, to date, been designed for Glock®, M&P®, and Springfield Armory® handguns, the concealed carry clips may be adapted for use on other similarly constructed handguns in the future.

The disclosure includes an apparatus and method for using a sling. The sling includes a lanyard portion and a magnetic retainer portion.
