Single Port or Dual Port Compensators. What's Better?
Compensators are a great improvement for managing recoil and tuning your firearm to improve target re-acquisition on follow up shots. The reduction in recoil balances the firearm out under fire and reduces the bounce-back effect you get when shooting. Also, if you are shooting for long periods, reduced fatigue is also a good side effect they offer.
So which should you choose?
Dual Port
If you are looking for the most performance out of your compensator and aren't worried about the added length, a dual port model is the top choice. It's improvements over a single port compensator are fairly drastic, reducing the recoil of your firearm 48-51% depending on your shooting characteristics, i.e. grip strength. A dual port compensator is more tailored to range/competition shooting, but it also is a great choice for EDC/CCW for people who don't mind carrying a larger firearm.
Single Port
Single port compensators are tailored more to the EDC/CCW scope of business. Their small size and reduced weight over a dual port compensator plays a huge role when carrying a micro or sub-compact firearm. They still offer a 28-31% reduction in recoil over no compensator, and improve the firearms shooting balance to be able to get back on target quicker and be more accurate with follow-up shots. This could be crucial in a scenario where quick shooting is needed. The small size of our single port compensators tailor themselves very well with CCW platforms, even on the micro sized platforms such as the Canik MC9.
In conclusion, a compensator is always better than no compensator, either model will improve your comfort and ability to grow your skills with shooting speed and accuracy. Choose one based on the needs your require out of your firearm.
