One question we get all the time is whether it’s possible to run smaller calibers through a suppressor.
The short answer is ‘Yes'; but, as with many things, there is a bit more to it than that.
Before going into details, it’s important to understand that caliber doesn’t matter much with suppressors. What matters is both bore size & pressure. In other words, if the bullet will fit through the suppressor’s bore, and the suppressor will handle the pressure of the round, then the suppressor will typically work with that caliber.
At this point you might be asking yourself why anyone makes smaller caliber suppressors at all? Well, it turns out that suppressors are much more efficient when the bore size matches the bullet size as closely as possible. Because of this, you can take a top-of-the-line suppressor for a larger caliber, and it will often perform like a bottom-of-the-line suppressor on the sub-caliber – even though the larger caliber can is both bigger and heavier.
At the end of the day, we are basically trading the efficiency of the smaller caliber suppressor for the versatility of the larger caliber model.
Although this isn’t something that is set in stone, there are a couple of rules I try to follow when purchasing a larger caliber suppressor on a sub-caliber weapon:
- If you don’t already have the larger caliber weapon, I would seriously consider just sticking with the suppressor that will fit your weapon now. In most cases, that will allow you to get a suppressor that is quieter & more compact, fits your needs more closely, and costs less.
- When you do select a larger caliber suppressor, try to get one that fits at least one weapon well. Most people end up with more than one suppressor because they really are a lot of fun – and you don’t want to wind up with one that is too much of a compromise and doesn’t fit the needs of any weapon very well.
As I already mentioned, using a larger caliber suppressor on a smaller caliber weapon really is a case of trading efficiency for versatility. Many people will find the allure of owning just one suppressor for multiple weapons to be well worth the trade-offs – while others will prefer to get the best fit for each weapon.
