How to choose A SIG P320 Threaded Barrel
Before moving on to the list, it is important to know what to look for when picking the right barrel for your weapon. Here are some of the things to consider when choosing barrels for your weapon, just like how you’d do with any other accessories.
Finishing
In order for barrels to last for a long time, the finish on the outside and the inside of the barrel must be good. Not only will your barrel last for a long time with a good coating, but it will also be easy to maintain and clean. Nitride and chrome are some of the most common coatings for barrels.
Rifling
The twist rate of a barrel is usually affected by the rifling and with good rifling, the accuracy of your weapon will be affected positively. Many barrels nowadays are using rifling with a button or 5R pattern so it is important to consider which is the best for your weapon.
Fluting
The fluting of a barrel will affect the weight distribution of your weapon and also affect the cooling effectiveness. Barrels that have fluting are usually lighter and have better cooling than non-fluted barrels. So the barrels should be fluted especially for compact frames.
Pros and Cons of P320 Threaded Barrel
Pros
Adding a muzzle device
A barrel that has threads will allow you to mount muzzle devices like a suppressor or a compensator that can help to reduce muzzle rise or silent your weapon. If you prefer your weapon to be less noisy, especially shooting in an indoor range, it is ideal to have a barrel with threads so that you can mount a silencer.
Improving velocity
Threaded barrels are usually slightly longer than non-threaded ones and the difference in length can have effects on the velocity of your bullets. The longer the barrel, the higher the velocity of the bullet.
Cons
Holster issues
A threaded barrel will usually stick out from the frame of the handgun and this will cause some problems with holster as well as affecting the comfort of the user. It can also potentially affect the concealability of your weapon which is something to take note of.
Not commonly used
Even though muzzle devices are a common attachment for pistols, not many people actually use it. Some people may also find it useless which is why it is not very commonly used.

Frequently Asked Questions (FAQs)
Is the SIG P320 better than Glock?
Depends. Many people think that for the SIG P320 to be better than a Glock 19 or a Glock 17, it needs to be much better to even replace the Glock. However, that is not entirely true.

On the other hand, the Glock is a handgun that is easy to carry in your holster on a daily basis.
Are SIG P320 with threaded barrels more accurate?
Yes. A barrel that has threading is longer and thus, bullets travel faster. The result of that is better accuracy. However, not many people are able to use it to its full potential since the improvement of accuracy is very debatable.
Is a match grade barrel better?
Depends. Some companies make a match grade barrel that is actually the quality of another company’s normal barrel only, it will have to depend on what the normal tolerances are.
