Magnaporting question

[DavidS]

I saw magnaporting listed as one of the 'improvements' that can be made. I knew what it is, but not really why it is. So, I did a small amount of research and this is what I gathered in my nutshell.

Magaporting:
-reduces muzzle flip up
-does not reduce recoil much but keeps it more linear and it feels reduced
-increases the sound level

Is that about it or did I miss something?

[CJB]

It can reduce felt recoil by incrementally releasing propellent gasses from the barrel

It varies with handguns but about 40 percent of rifle recoil is from the hot gas that propells the bullet. That is due to the jet effect, same as a jet engine, or rocket engine.

Incrementally releasing gasses in a direction other than forward, the effect of the gas is diverted against those directions. This helps flip.

Some rifle porting has two sets of slotted ports. One set directly perpendicular to vertical, the other set at an angle to vertical. The first set is additional gas release, but is not directed in a manner to negate flip.

On handguns.... the effect is much smaller, as the percentage of recoil from the expulsion of propellent gasses is quite a bit smaller

I magna ported my K40. I know Jocko is a big fan of magna porting.

I think it looks good. I didn't notice a ton of difference in recoil but it did help a bit with the muzzle flip.

I like the looks of it, I'd do it just for that since looking cool is pretty much job # 1.

I'm audio challenged but I don't think the noise is much worse either.

Some say you lose a lot of velocity, Magna port says very little. Didn't effect my point of aim or anything.

The only thing you missed is that magnaporting increases muzzle flash. I can see porting a magnum handgun, but a 9mm has very little recoil, especially in a Kahr pistol which has a very low bore axis. Jocko might disagree with that statement and call me a dick for mentioning it.

[DavidS]

Thank you

Also, not so much with a semi, but when you magnaport big bore handguns.......the guy that has to shoot next to you at the range, hates your guts.....................

hgas to make up his own mind on porting. Muzzle flash is B. S. Muggs, u don't see muzzle flash anymore in a ported gun than a non ported gun, if u do then ur certainly not concentratingon the trarget. Maybe at nite time u will see more but again that is a mute point IMO. If I can see it the fokking bad guy can see it and he has no clue what it is. It might be a damn grenade rounmd or a RPG, he don't know, u do but again, that is a non issue IMO. I have shoot um for over 30 years, I can't say I have went out to test a ported gun at nite, never really grabbeb my crank to do that either, for it is what it is.
Colonel is right thoughh, it looks great , it does work, felt recoil is less but again bigger the caliber the less felt recoil to, in a 9mm really not needed but again, it certaily doesn't hurt a damn thing. What little velocity is losse and I think magna port staes 6-8% , I seriously doubt if the bad guy is gonna notice it. All the horror stories u hear about ported guns IMO are just that, but I gues sif u wanna hold the fokking gun under ur nose or ur balls ande pull the trigger u might get some blast from the porting area.

Like polishing a gun to mirror finish or leaving it matt, it is a decison u have tomake. I just love um, for no more reason that I can say I just luv um. I would let no one port my handguns except Magna port. Just my 21 cents on this.
Muggyur brain is ported, fokker is full of holes

Pretty much what they said....probably unnecessary with a short barrel semi handgun....incremental if any benefit to muzzle flip. Increase flash, noise, cost. More beneficial with rifle and big bore longer barrel revolvers. I had it done to my 300 Win Mag rifle, but have not shot it yet. However, before you do it to your Kahr, check with Kahr about your warranty. I was told by Kahr that it voids your warranty. You may want to pursue this answer for yourself and let us know what they say these days. Some guys swear by magna porting, especially those with larger cal handguns and rifles. Getting it done probably won't hurt much of anything other than flash from some ammo, expense and warranty.

Iwouldsasy if u have a barrel issue with kahr, they might want to blame it on the porting but otherwise if the trigger system breaks. or the gun is defective for anything utter than porting, they will indeed take care of it. I would guess u will gt a company lawyer answer if u ask them, If that is an issue with a person doing it, then one should just pass on it, as so may guns today are factory ported. I have never heard of any issue with ported guns as far as warranty goes. I do know when I got my P380 kahr I wrote to magna port and ask about porting the gun and they said NO, not enough barrel thickness, so I think they also are wise enought to just not carte blance port nygun sent to them.

I know applied plating company ported my little kel teck 380 for me, drilled two holes in the slide and barrel, looked cool., didn't do jack sh!t, but never gave an issue either.

I shot a .300 Win Mag. once and once was enough. I test fired it for my dad using blue pill loads. My shoulder still hurts to this day.

Muggyus rain is ported, fokker is full of holes

For crying out loud, Jocko. You don't see the muzzle flash, because you shoot with your eyes closed and don't care what you hit. I shoot with both eyes open.

[Bawanna]

Which brings us to the question......how does one not cry out loud. Is it possible to cry silently?

[getsome]

Did Jocko say that Muggsy had his fokker ported?....Bet that smarted...

Thanks for all the responses, even the off-topic ones. Magnaporting will not be for me.
