I have decided I want to get the barrel ported for my Sig P226 to reduce muzzle flip and increase speed when rapid firing. I considered the idea of getting a compensator put on. I decided not to however since this would make it harder to conceal carry and definitely a lot harder to find holsters that fit. Been doing research and trying to figure out the best way to get it ported. There is a company called Magna Port that cuts slot ports through the slide and barrel at around the 11 and 1 O’clock positions on top of the barrel so they are slightly offset from the center top. This makes the gas vent out the top in a V-shaped pattern which is meant to prevent front site fouling and flash blindness when firing at night. There is another company called Accurate Arms that puts the ports directly in center on top of the barrel and slide. I heard people say this positioning works better for reducing muzzle flip but can cause problems with site fouling and firing at night due to the flash shooting straight up. Does anyone have an opinion either way on which positioning of ports works best? Thanks in advance.
@Jeffrey367 Welcome to our community, we are glad to have you with us. 
Some thoughts on that. 
Thanks Bruce. Appreciate the feedback!
I’m very far from an expert and opinions are like Aholes. I think I would try to figure out how to make a screw on compensator work. I don’t like fussing around with factory work. I’ve screwed up too many things to only have to rebuy and live with what I don’t like. I would rather work on a holster and practice my draw than spend another $500 or much more because I don’t like the final product.
Consider that by adding a compensator you are also adding length and weight to the firearm, which changes the balance point and the grip strength required to manipulate the weapon. Some reports I have read (I have no personal experience) seem to indicate that what you may gain from the compensator can be lost through the additional weight as well as the changed balance and handling characteristics. Then again, one person’s folly is another person’s genius.
If you are committed to the idea, do TONS of research and use your best judgement. Maybe you can find a way to fire some handguns with ported barrels and some with compensators? That way you might find out what they can do FOR YOU.
Good luck, and welcome.
@Jeffrey367 , welcome to the Community 
My response won’t be accurate for you but this is something I’ve been discussing a lot with my friends.
Adding something extra to EDC always comes with extra steps in purchasing or adjusting the gear and then doing things a little differently.
Is it worthy? Maybe yes, maybe not. It definitely requires time and money. Advantage? I’m not sure.
Me and my friends found that training, practice, making corrections and trying to be more efficient saves money and makes are better shooters without adding fancy stuff to the firearm.
Additionally when we take other gun we still shoot great, no needed to compensate recoil, nor muzzle flip.
The point is… practicing good techniques eliminates needs for adding stuff to you EDC.
As I mentioned… it’s not an answer to your question, however I wanted to use this thread to point the importance of training vs. making your pistol shoot faster. (Which is subjective).
Jeffery367 - There is a company called Springer Precision that has custom accessories for multiple brands of firearms, and they also do custom work. I looked at their website yesterday for pricing and they seemed to be fairly reasonable. You may want to add them to your list to check out for modifications.
Just for gun contact Sig and see if they have a custom shop that could give you their take on porting your gun. Just a thought.
I have great success with Mag-Na-Port. I have handguns, shotguns, and rifles they have ported. The porting works best with the higher pressure the round. Has tamed .375 H&H Mag, .44 Mag, 9mm Kimber solo, etc, etc. A family run business with great customer service.
Welcome to the Community Jeffrey367.
Thank for the information. Welcome to the Community Jens1
The founder Larry Kelly started out making ball valves for NASA during the
Apollo space program then started Magnaport Int. in Mt Clemens Mi.
porting barrels. their work is top quality
Larry is probably gone by now but the family still runs the business
they use to have tours years ago , not sure now
I cant believe this discussion is still ongoing! MOST police departments have banned these. Anything that can cause night blindness and put your life in jeopardy is two thumbs down!!!
@Jeffrey367 and @JENS1 Welcome to the community!
Hello and welcome @Jeffrey367
My comp’d pistol is a CR920P, the holster I use is for a G48. So without the comp it would fit in a G43 holster. I would get a threaded barrel/comp and use a longer holster. You shouldn’t have any issues with concealment because it’s the length of the slide, not the length of the grip. Hth
I should have mentioned Mag-Na-Porting my S&W 360PD .357 made the Scandium gun pleasant with .38 Special loads and tolerable with .357 loads.
When Glock first came up with factory ported guns like the 23C we were quick to get to play with some. Fortunately one of my mentors got one from work for evaluation and quickly found out that from some of the shooting positions we train in he ended up with a faceful of hot debris and on another one his shirt caught fire. All potted barrels were quickly replaced with solid ones.
With proper shooting form and grip the recoil of a 9mm, especially in a full sized handgun can be easily managed without ports, so accurate follow-up shots can be executed as fast as they’d ever need to, and quite frankly the 9mm does not put out enough pressure to make a compensator of much use.
Just something to think about.
Thanks Patrick, I will check them out.
Thanks for sharing your personal experiences Jens. That is exactly the type of input I was hoping for.
Thanks Karen
