    I voted no. I would never port a defensive weapon, which is pretty much all a j frame could ever be. You may need to use your weapon at night and the muzzle flash from a ported gun will pretty much ruin your night vision for a little while.

    As far as pro's and con's from what I can see.
    Pro's:
    - Reduces recoil.
    - Looks cool.

    Con's:
    - Could ruin your night vision in a fight and give the BG the upper hand. This is a HUGE downside for me and in my mind would rule out porting it.

    Just my .02. Best of luck in what you decide.

    I just don't see a reason to port a defense weapon either. Competition guns may use porting, but an edc....naww.

    I would be interested to hear from anyone who has done it. Seems like it would kill even more velocity. But I definitely wouldn't on a carry gun.

    I too would vote no on the EDC weapon. I could see it causing a real prob with a night shot... but everyone is correct... It does look kewl.

    I have a gun like that (model 642) and don't believe the recoil or muzzle jump is enough to justify porting. Other disadvantages have been mentioned above, and include velocity loss, lots of bright flash and noise, and the possibility of hot bits of powder coming down on your hand.

    If you are shooting +P .38 ammo and are porting it to reduce recoil, consider that you will probably lose the "+P" velocity increment from the porting. You might as well shoot standard pressure ammo and leave the gun unported - it will have the same net effect and save the porting expense.

    That's a really good point that I didn't think about. It does look cool though!

    It's useful for .357 Magnum in smaller, lighter weight guns.

    Although I dislike shooting .357 Magnum loads in J-frames, even in those J-frames appropriate for that round, I have three Ruger SP101s so treated, and they are gems, and make shooting .357 Magnum loads in a lightweight gun pleasant.

    Porting is simply unnecessary for shooting .38 Special loads, IMNSHO.

    Other than what's been said before...I voted NO. You could not fire through your pocket (if necessary to do that). If reducing recoil is your main motivation, I would suggest getting Crimson Trace laser grips (LG 405). It has a padded backstrap. You would also get the added benefit of a laser.

    The whole night vision thing is the least of my worries about porting a defensive pistol... I'm far more concearned about where all that hot gas is going to go in a CQB situation; in my hand, in my side... that stuff coming out of the porting can and will do some nasty damage.

    No thanks, I dont want anything to do with porting, I prefer all the nasty stuff being directed towards the BG. Also, if I really think porting is going to help me, I need to shoot a smaller caliber or get some training, perferably both.

    Ditto the no vote for loss of night vision. Same reason makes compensated Glocks a bad idea, IMHO.

    You barely have enough barrel to build velocity as it is.

    I actually did have one ported

    I've mentioned it before in a few past posts.
    It was a S&W Bodyguard.

    I had it done as a spur of the moment thing & it was many moons ago.
    I had sent the BodyGuard to Mag-Na-Port International originally for an action & trigger job and then I decided to have the revolver refinished in Metal-Life Chrome and also have Chrome done on the internals to really "slick it up."
    I think it was then that I gave the go-ahead for the porting job.
    I do think it did somewhat reduce shot to shot recovery time when shooting extreme rapid fire with HOT-HOT .38.
    Mag-Na-Port porting does an incredible job of properly the ports and directing gases and they did do a beautiful job EDMing the ports with no decrease in accuracy.
    Super neat job.
    Actually, shooting any really hot defensive loads in a snubbie at night...you're getting a fireball regardless. So I'm not sure you're going to get much if any increased night vision degradation due to porting.
    I can see some potential for vented hot gas and particulate causing some unwanted problems depending on where you're shooting from aka retention.
    When I switched over to carrying only semi-auto - I traded the S&W back and shortly thereafter it did score a killing head shot on a drug dealer for the LEO that bought it. For whatever that info is worth.

    BTW: I'm not sure I would ever go for the two or three port holes.
    Mag-Na-Port would be the only folks that I would ever let do a porting job on any of my guns.
    That would be because of the way their ports are designed and located.

    Try shooting with one from retention...it's an experience you won't forget...
