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 rear 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 XD handguns, the concealed carry clips may be adapted for use on other similarly constructed handguns in the future.

A process for making nanoparticles of biocompatible materials, 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. Also, biocompatibe nanoparticles comprised of cerium oxide, ethyenediaminedisuccinic acid, and optionally citric acid. An increase in catalase-like enzyme activity is demonstrated by cerium oxide nanoparticles prepared with citric acid and ethylenediaminedisuccinic acid.

Attachment systems configured to fixedly hold a rail are described, including a first connector integrated with a tactical accessory mount, a base element, including a first engagement portion configured to at least partially wrap around a first edge of the rail, and a movable element configured to move relative to the base and including a second engagement portion configured to at least partially wrap around a second edge e of the rail. A locking mechanism is provided to hold the movable element in a closed position with the second engagement portion holding the second edge of the rail and the first engagement portion holding the first edge of the rail. A second connector may be attached to the base element to hold the base element to the tactical accessory mount via the first connector.

The present invention relates to a gun belt with an integrated holster retention system where by a holsters J, M or similar style hook sits in a pocket formed by the belts outer layer and attached narrower bottom inner layer. The hook than engages the upper layer thus holding the holster in place.

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.
