One of the most frequently asked questions by gun users is whether a firearm is suitable for dry firing. Experts warn that this process can cause serious damage, especially in older model rimfire guns.
To give an example, in older rimfire models such as the Mossberg 151 MB or High Standard HD, because the firing pin is made of a harder material than the barrel or chamber, the pin strikes the chamber edge directly when there is no cartridge present. This can damage the chamber and lead to feeding and extraction failures. For this reason, dry firing is definitely not recommended for these models.
Conversely, in modern rimfire models like the Ruger Mark series or the 10/22, the firing pin is prevented from contacting the chamber edge due to the presence of a firing pin stop. It is stated that dry firing is mostly safe in such modern guns. However, since this feature is not present in some newly produced models, users are advised to review their manuals or contact the manufacturer.
It is noted that dry firing does not pose a problem in centerfire guns (including AR-15s, AK platforms, shotguns, and modern pistols). In these guns, since the firing pin moves towards an empty void in the chamber, it does not damage any parts. However, experts remind users to fully comply with safety rules by ensuring their guns are absolutely empty.
Dry firing is also not recommended for revolver models, particularly older rimfires or certain classic Colt productions. Since the firing pin is often integral to the hammer in these models, repair can be both costly and difficult if it breaks.
The suggested solution for models where dry firing is risky is aluminum-bodied training cartridges known as “snap caps.” These products feature a primer area made of soft material to cushion the impact of the firing pin. Rimfire snap cap models are also manufactured specifically to protect the edge of the chamber.
Experts recommend that users who are unsure about which gun is suitable for dry firing contact the manufacturers or consult technical support lines.
