Your Guide to Buying

buying guide


There’s a wide variety of silencers for guns on the market, and one thing to consider before buying one is the budget. Since the silencers for handguns tend to be expensive because of the material, you may want to check which brands fit your budget. After all, a caliber 45 suppressor should not break your bank. 

Hearing Safe

The hearing loss and tinnitus from repeated exposure to impulse firearm noise can affect the shooters [1]. The suppressed pistol is designed to reduce the sudden release of pressure of gas that generates an extremely loud noise. 

The caliber suppressors can reduce decibel rating at an average of 20-35 DB, which works as a hearing safe as earplugs and earmuffs.


Aside from an aesthetically pleasing finish, the designs fall into two types. The design for the caliber silencer can either be full circumference gas seal or user-serviceable. The design can be field strip and clean. Both are monocore and baffle stacks and can have fixed barrel spacers. 

In addition to this, the designs are convenient to use and striking. It is not harmful to accuracy, and all of these can be achieved while in decibel reduction. 

Easy Installation

The easiest way to install a gun muffler is through a direct thread mount, which is the most common way for fixed mounts of a muffler. Since the can is threaded, you screw it. Another way to install a 45 suppressor is the quick disconnect if there are no threaded barrels. 


Another thing to consider is the performance of the accessory. One obvious reason to use one is for hearing protection. As much as you want to reduce the noise, the first benefactor is the user itself. Caliber suppressors also help to lower noise pollution, reduce recoil and make the shooter more accurate.

Thinking that a handgun suppressor can reduce noise, a longer 45 suppressor tends to be quieter. But our team suggests never getting a very long muffler because it has many drawbacks for many guns. Be reminded that your handgun muffler has to hang off at the end of your rifle calibers. You have to compromise and get at least 6 to 9 inches in length, dual or fixed length. 


Unless you use it for big magnum calibers, we strongly suggest getting a lightweight and compact model. The lighter the weight of the silencer for guns, the less impact will be felt. It would be best to check the materials as it also gives a factor to the weight like the stainless steel and aluminum. 

Build Materials

Stainless steel, Ti, and aluminum mount are some of the highly recommended build materials you should check before buying a muffler for guns. An aluminum mount and stainless steel are incredibly lightweight and less expensive than other materials. It is also proven and tested that will last for years. 

User Serviceability

Our team highly recommends buying mufflers of handguns that are user-serviceable. Suppressors get dirty, especially those pistols and rimfire rounds that require daily cleaning. The lead bits and residue that exits the muzzle can build up and get a user-serviceable silencer that is not easy to take apart and clean. 

Full Auto-Rating

A silencer that is auto full rated can hold up rapid firing. The materials have a high tolerance to heat and contain high-strength baffles. It can handle the heat from the cartridge and will not degrade after reaching the stabilized temperature with the materials. If the materials are too soft for high temperatures, they will erode faster, and it is a waste of money.
