Mag Na Porting !!! Do or Don't ???

[andyo5]

Magnaporting will reduce muzzle flip, but will also increase noise and if you shoot the gun at night the flash from the magnaports will tend to mess with your vision temporarily (like shining a flash light into your eyes). This could be bad in a defense situation.
See if you can borrow a gun that has been magnaported and try it out at night, before making your final decision.
Frankly, I would not shoot .357s in a J frame. I tried it, and concluded that I'd want a heavier gun (like a 4" 686).
Or as another option, consider the Ruger polymer framed revolver (LCR, I think). Polymer framed guns tend to absorb recoil much better than all metal guns. I have a 20 ounce Kahr .45ACP and it is actually very easy to shoot well.

Another dissenting opinion here. I just purchased a 629 Performance Center gun with the 3" barrel and factory Magna-Porting. The port is in front of the front sight and I've noticed minimal fouling of the sight...if any. It definitely reduces the felt recoil. Which is appreciated. Because recoil is still plenty stiff with 240 grain .44 mag factory loads.

Don't really have an opinion on porting, but here is a picture of a 60-15 as requested. I have seen a 60-15 Pro that was ported for sale at a local GS.

I had a 29-2 done about 30 years ago. Would NOT do it again, at least on .44 Mag and below. Recoil changed into a two piece back and downward snap that was to me more disconcerting than the old recoil. Flash and noise were worse. Also the red ramp insert shrank quickly thereafter (hot gasses?). After the new wore off, I have shot that gun very little in the intervening years.

There's porting and there's Mag-Na-Port. They both do the same thing, but the port on your 629 is not Mag-Na-Port.

I had a few of my guns ported by mag na port and doubt that I'd do it again. I find the improvement to be slight and can't really say I felt a difference.

When looking for revolvers there seem to be more Mag Ports available of a particular model than ones without which to me indicates they become a bit harder to sell.
