Has anyone here
A. owned one ?
B. Shot one ?
C. seen one, in person ?
D. seen one on the inner net ?

Well.... Kinda. Ported BHP. I bought it used some years ago and the previous owner claimed it was done by Mag-Na-Port.
It worked fine but the V shaped muzzle flash was not a bonus. I sold it, like a moron.

I had a Colt CCO that I had Magna Ported. It helped with recoil somewhat. They did nice work.

I have an alloy officer's 1911 in 45 ACP. I think it's magna ported because of the shape of the ports. Unless I use full power loads the porting does nothing. I get more muzzle flip with 185 and 200 grain target loads than I get with 230 ball. With full power 230 or any self defense load I get almost no muzzle flip and a sharp but very manageable straight back push.

I have a 1994 Magna-ported P220 in my safe currently. I wasn't crazy about the gun, but the price was right at the time. Not sure when the Magna-porting was done, but I don't notice enough of a difference between this guy and another P220 I own to care. I haven't shot it in a while, but I don't remember much if any muzzle flash.

It may not be as noticeable in daylight, but try shooting it at night, or in low-light conditions. Or even just indoors.

The ported handguns I've shot in lower light conditions have had noticeably brighter muzzle flash, especially since a significant portion is being directed upwards and directly into the shooter's line of sight.

very nice , thanks

Muzzle flash is more dependent on the ammo than any porting. I don't have any semi's that are ported, nor would I want one. All of my SD revolvers have Magna-Porting done back in the early 1990's.

Some comments:

1) I've tested my Ruger SP101 3" .357 Mag in pitch darkness with full power loads. You'd expect a ball of fire, right? Using a premium SD load with flame retardant powder, like Federal 125 gr JHP's, the flame signature is poop. No significant flash, no blinding...nada.

2) On the other hand, I saw one guy shoot a .357 Mag with a stock 6" barrel in low light (ambient) conditions on the indoor range. Jeez, a humongous fireball. Here's the difference. He was using factory el-cheapo 158 gr .357 Mags. Yeah, the powder makes a difference.

Finally, my experience with revolvers has been the following. Magna-Porting (at least in revolvers) doesn't reduce recoil, it simply redirects it giving you better control and less muzzle rise. In my testing, the muzzle rise on all of my revolvers was reduced by half. It allowed quicker follow up shots with smaller groups when using double taps. In addition, due to the lessened muzzle rise, it directed the recoil through the grips to the meaty palm of the hand rather than to the sensitive web between the thumb and next finger.

All of the above was true with guns from L frames to J-frames. While the effect is more pronounced with full power loads, it was also noticeable with practice loads. Even my S&W M60 2" in .38 Spl benefited. The myth that it only works well for large caliber magnums was not accurate. I make no claims that the above is valid for semi's as well, have no idea. Never had a semi with Magna-Porting. However, I did extensive testing with a large variety of revolvers and found the above to be true.

Thanks Nipper, great write up.

Years ago I got a few rounds through one of the Michigan Armament guns with factory Magnaport Auto Port cut through slide and barrel. I could not tell much difference with the ammo on hand.

A guy here had a Magnaport custom .44 Ruger. I didn't get to shoot that one, but he said it reduced muzzle rise. It also smoked his red insert front sight pretty quickly, too.

Years ago, I had several guns Magnaported.
One was a 7mm Remington Magnum rifle. It helped with muzzle rise, but, put more recoil in to my shoulder. Same with .44 magnum pistol. Smaller calibers had little noticeable difference because they don't have as much gas to work the ports.

I have had MagnaPort do their "thing" to a few of my handguns, but none of them were 1911s. I like the end result, and own quite a few Factory ported handguns, including a SA V-10 1911.

I can only speak to the M29 that I have, when I sent it in I requested the porting. It still stings with the Hornady 300gr'ers I normally carry in it but the muzzle flip is much less pronounced.

I can burn through a cylinder pretty fast, especially if I swap the wood grips out with the compact Pachmayrs.

I agree with Nipper, too. My 4" 29-2 was magnaported straight from Massachusetts to Michigan. It makes it easily manageable, but still not comfortable to shoot.
