Magnaport on revolvers

Long ago I used my 629-1 for side matches. Usually 48 shots.
The magnaporting definitely helped for target acquisition.
I did not notice any less felt recoil.
 
My M29 would utterly cover the red ramp front sight with gray residue within 10 rounds when using any velocity lead bullets. Cleaning lead residue from the ports was as much fun as plucking nasal hairs.

It's a little late; 12:40 AM. This made me laugh out loud! I've never heard that phrase but I sure as heck will remember it! Thanks for that!

I shot a S&W model 58 .41 Magnum, and a 12 Ga. shotgun with the actual Magnaport system. I'm not a fan. Magnaporting certainly did reduce muzzle rise, with the result that both those guns recoiled much more straight back, hard.
 
If suppressors make friends, ported guns make enemy’s. Example of the effect: Ported Smith 500 blew the battery cover off of our LabRadar…we just happened to record it or we wouldn’t have believed it. …but they sure look cool! (Fortunately the 500 ported portion of the barrel is convertible, which was forward looking by the folks at Smith). Side note, ported barrels and ultrasonics are perfect together.

Have a bunch of ported guns...and enjoy them just as much as my unported ones...

S&W 58 Mag-Na-Port Quad-Port

S&W 657 3" Mag-Na-Port

S&W 60-10 3" Lew Horton Small Hunter Mag-Na-Port

Freedom Arms 654 .41 Magnum 6" Mag-Na-Port

Freedom Arms 83 .475 Linebaugh 6" Mag-Na-Port

S&W 500 4"

Taurus Tracker stainless 4" .41 Magnum

Taurus Tracker stainless 4" .45 ACP

Taurus Tracker titanium 4" .41 Magnum

Taurus Tracker titanium 6" .41 Magnum


Have shot the M-58 back to back during an IDPA shoot with an unported one. The load was 8.0 grains of Unique with a 210 plated bullet. The recovery time between shoots was very noticeable. Also with the 60-10...have an unported one and can feel the difference with .38s and .357s.

As to cleaning the ports after using lead bullets...zero issues.

Rather than bump my other thread, linked above, I have a recent answer to your specific question. I recently sold a 629MG because I just found it brutal with the magnums. By that, I refer to the punishment felt in the hand.

Last week, I found another 629MG, which was Magnaported. So, I said, what the Heck. It works, I could get the muzzle down for a double-tap! Yes, certainly the muzzle didn't climb as much, but what I felt was more tolerable. I don't know how the physics add-up, but in my case, I'm happy.

I LOVE how Jerry points that out to you in those videos linked above. He tells you to focus on his wrists, and you can see how the concussion ripples along his forearm in each example.
 
S&W has shipped revolvers to be Magna Ported.... My 3" Model 66.

Flip reducer

Back to the O.P.s original question; Does it
really help with muzzle flip?

On my S&W Light Hunter 6"bbl 44Rem Mag,
the barrel porting does keep muzzle flip down.
Also this a heavy Revolver which helps steady shots

Slightly off topic.

I have a S&W MP Shield 9mm, v.2, Perf Center model which is ported X # 3 on each side of the slide. Does it help? A little. Is it necessary? Probably not.
 
Interesting thread. Several decades ago I had a 4 inch model 29 Mag-na-ported, and then some years later had a 4 inch Model 629 dual Mag-na-ported. Just bought a 329PD and although I have not shot it yet, it's going to Mag-na-port for dual ports. Just found out something I did not know. For them to port the sleeved barrels, the barrel and sleeve must be removed from the frame, therefore the fee is much higher.
 
With something like a Smith and Wesson .460 that slings 200grain pills at a velocity an AK slings 7.62's... yeah... porting is most certainly needed and I have first hand experience doing so. With, say a 44Mag, no, not necessary and any difference is very negligible between a ported and non-ported barrel; and I shoot the Heavies out of a 3" barreled M629-5 regularly, (before the stupidity and shortages of late anyways)... The fireball(s) and gas spewing to get back on target/sight overrides any of the minor muzzle flip dissipation any porting provides in the wonderful .44Magnum and my favorite, .44Special caliber(s).

The heavier .454 to the 500Maggies though I must admit do benefit from porting/muzzle devices that offer the same recoil dissipation even with heavy barrels 8 inches long(er)...
 
I have only owned one ported gun.
I had a Dan Wesson 4” 44mag. It came with a ported barrel and a solid barrel. I was cautioned not to shoot cast bullets out of the ported barrel.
The ported barrel made shooting full house 44 mag a bit less unpleasant. Muzzle flip was reduced and rearward recoil may have been reduced slightly and I just could not tell.
The downside? The muzzle blast was horrendous. I was actually asked to move off the rifle range by the range officer after one cylinder full. Apparently the blast going up and away was bouncing off the sheet metal roof and bothering the rifle shooters? At least that is what he claimed and I do not argue with range officials.
