However, if your pistol has a super light spring, then you run the risk of light strikes as you try the thicker (magnum and small rifle) cup. You should always use the recommended primer type for your pistol, but in the event you are unable to obtain any of the regular primers, you could potentially use magnum primer or small rifle primers. The small pistol 9mm round has the thinnest cup, followed by the small pistol multi-purpose, followed by the small pistol magnum round, followed by the small rifle round. The reason cup thickness matters is that if the hammer in your weapon doesn’t apply enough pressure to the cup, the round will not discharge (this is a ‘light strike’). Though there are some other subtle differences, the cup thickness is the critical difference. The main difference between the three 9mm primer types is the thickness of the cup on the primer. You can view and buy a range of 9mm primers at. A small pistol primer measures approximately 0.175” in diameter. Small Pistol Multi-Purpose (regular or magnum)įor many, a small pistol primer, or small pistol multi-purpose primer will be adequate.Within this ‘small’ group there are four main types of 9mm primer: These are typically used to support rounds for 9mm, 38 special, and 357 magnum guns. In the case of a 9mm, you will be working with the ‘small’ primers. In general, there are two sizes of primer: large and small.
#RELOADING SUPPLIES 9MM PRIMERS FULL#
There are some overseas imports as well, but the four US makers are the main suppliers.īut after being recently bought out by another company, they are on their way back to full productivity. Remington has had significant issues as a company in the last few years, so they had to close down operations for a period of time, and even when operating, were operating under capacity. Who Makes 9mm Primers?ĩmm primers are made by the four main ammunition makers: On top of that, all the health and geopolitical complications made shipping and imports trickier than they have been for a long time, which influenced not only the importing of manufactured ammunition but some of the critical ingredients required to make the ammunition.
As a result, supplies got bought up very quickly. The two factors are an increase in demand for primers and disruption to normal manufacturing.īecause of COVID-19 and other political concerns, more people bought guns than ever before, and those that already had guns then wanted to stockpile ammo in the face of uncertainty. There are two main factors that have influenced the primer shortage that we have experienced over the last few years. What Caused This Shortage Of 9mm Primers? As a result, it forced people to ask the question of whether other primers could be used for 9mm reloads. In recent years there has been an extreme shortage of 9mm pistol primers to the point they were basically unavailable. The 9mm pistol has become one of the most popular handguns, thus, 9mm primers are in high demand. If your handgun has a lightened or modified trigger/action, you may need to use softer primers.Primers come in a variety of different sizes, with each primer varying in size slightly between each manufacturer.ĩmm rounds are some of the most common rounds used for both target shooting and self-defense. Some primers are softer (Federal), some are harder (CCI typically), and some fall inbetween (Winchester). The hardness of the primer refers to the amount of force required to ignite the primer. In some cases, a primer can be formulated to work with both regular and magnum loads (See WLP below). Magnum loads require more activation energy since there is a lot more powder to burn. Non-magnum loads (such as 38 special) only require a small flame to properly ignite the powder charge. The type of primer indicates the overall intensity of the primer flame. Primer type (Regular, Magnum, Multi-Purpose).Depending on what cartridge you are reloading, you need to buy the proper size primer for that application. Some cartridges require a large pistol primer (45acp, 44 special, 44 magnum, …) while others require a small pistol primer (9mm, 38 special, 357 magnum, …). There are a few basic parameters that you need to evaluate when buying primers: Pistol primers side by side: 44 magnum (large pistol primer) and 357 magnum (small pistol primer)
Primers are typically sold in packs of 100, or bricks of 1000 (10 packs of 100). When the primer ignites, it shootes a high intensity flame through the flash hole (hole between primer pocket and case interior) which ignites the powder charge. The primer is stuck by the hammer or firing pin, and when struck it ignites. Primers are small metal cups filled with high explosive compound.
