Is “Porting” a Carry/Defense Gun a Bad Idea?

How often should I change out the self-defense ammo in my carry gun. It is to expensive for me to practice to much with it. So how long can I keep it and be sure it is reliable? I know that in a controlled environment ammo will stay fresh and reliable for years, but living in Wisconsin my carry gun ammo is subjected to a wide range of temperature and moisture changes daily. I think this might shorten the life.

Porting is the practice of cutting slots at the end of the barrel so that gas is directed up and, usually, to either side of the barrel at slight angles when the gun is fired. This is done to reduce recoil and allow for better control and recovery time between shots. This sounds like a good idea if you’re shooting in defense of life–shoot faster and be surer of getting back on target. But it’s not something you should do. Here’s why:

Take your carry weapon and put it in three positions. One, on the hip as if you had leveled it right out of the holster to make a fast very-close-range shot. Second position is to bring it up to what is usually called the #2 position of the 4-count drawstroke or the pectoral index–thumb against the side of the chest, gun angled slightly out. Again, this is a position you might take for a very-close-range shot against an attacker in arm’s reach or coming in on you. Third position is what is sometimes called close-contact or the #3 position of the four-count: two hand hold but gun drawn in as close to the sternum as your arms and wrists will allow.

In each position, look down and note where the end of the slide or barrel is at the muzzle end. That’s where the ports will be cut, and that’s where the hot gases and hot unburnt powder will come from out of that port to go into your face and eyes when you fire from that position.

The technical term for the results of that in a fight for life is Not Good.

Also, in low-light or full-dark conditions, the flash from the ports is large and bright and won’t help your ability to see things after the first shot or two. But the main problem is the stuff in your face from a close-in shot.

So: Port competition-only weapons if you want. Port hunting weapons if you want. Port weapons you won’t ever carry for self-defense if you want. You can control where and how you shoot those. But for the defensive weapon, where you won’t have control of the circumstances where you will have to shoot it to save your life?

Don’t do it.

I could use some information on purchasing first aid supplies I have seen many advertisements for first aid bags that has many items and only half of the items are of value the other half you can purchase it in any drug store such as Band-Aids aspirin and things like that. Even some of the trauma bags have a lot of things you can find any place. I am looking for a bag that has the essential items that are necessary. Maybe I should just try and buy everything separately. Anybody know of any good websites for quality items that you cannot always find in those commercialized bags that have a lot of stocking stuffer items put in them just to take up space? I am not necessarily looking for a big kit, just one that has the right stuff in it.
