Gunsmithing Tools for Pistols and Revolvers

Posted January 19, 2015 1:23 PM by Brush Research

Handgun maintenance is essential for the proper functioning of semi-automatic pistols and revolvers. Flex-Hone for Firearms tools from Brush Research Manufacturing (BRM) remove build-ups of primer, gun powder, and ammunition casing materials from handgun cylinders. BRM's gunsmithing tools also remove surface irregularities such as machining or tooling marks. For cowboy action shooters, these reliable brushing tools are a good choice for removing residues from wax bullets.

Flexible honing for handgun cylinders imparts a finish that's free from these and other surface imperfections. BRM Flex-Hone for Firearms tools also impart a series of regular grooves that promote optimum lubrication. Firearms manufacturers, gunsmiths, gun collectors, and handgun owners alike also appreciate how flexible honing imparts a surface finish that looks great and helps to protect gun parts from fouling and corrosion.

Handgun Maintenance

As an experienced supplier of surface finishing solutions, Brush Research understands the needs of the firearms industry. Without proper maintenance, semi-automatic pistols can experience misfeeds, failures to eject (stove pipes), and misfires. Residues on the follower, feed ramp, bolt face access, or extractor groove can prevent a cartridge from chambering properly. Build-ups at the chamber's breech can keep cartridges from fully loading, leaving the bullet rim unsupported.

Revolvers can also malfunction if they're not maintained. For new shooters, it's important to remember to hold the muzzle upwards while extracting spent shells. Otherwise, burned powder residue and unburned gun powder can become lodged under the star extractor, preventing the star from fully seating in the cylinder recess. Problems associated with a residues can also affect experienced shooters, which is why periodic gun maintenance is so important.

Flexible Hones for Handgun Cylinders

BRM supplies chamber hones for a variety of handguns, including .32, .357 MAG / .38 cylinder, .41 MAG, .44 MAG, .45 ACP, .45 Colt, and 9mm. These Made in the USA Flex-Hone tools have a 1-5/8" abrasive part and an overall length (OAL) of 3 inches. Depending on your surface finishing requirements, choose silicon carbide (SC) abrasive in either 400 or 800 grit. If a surface requires significant improvement, start with a lower-grit tool and then use a higher-grit tool for the final finish.

Flex-Hone for Firearms tools are also available for maintaining the slides on semi-automatic pistols made by Smith & Wesson, Beretta, and Sig Sauer. These 800-grit SC tools have an overall length (OAL) of 8 inches. Handgun owners can also choose gunsmithing tools for the slide lug area or the main spring housing in Model 1911 firearms. M1911 pistols are used by military and law enforcement personnel, and remain a favorite of recreational shooters.

Why would I want to remove material from a precision fitment?
