Porting the slide...

[In-Yo-Grill]

Are there any other reputable places to get a slide ported other than Magnaport?

I know of anyone who uses rthe edm process, Many smittys will drill round holes in the slide and barrel and call it ported. depends what you want.

For the money magna port does the finest job, no refinsih required, trapazodial ports instead of round holes that are designed (according to magna port) to work better.

Ihave owned many magna ported guns over the past 30 years and I do feel they do the best work around and their prices IMO are good.

That's who I'll probably use I just wanted to know of any other potential options.

While I haven't even shot it yet I think Magna Port did a beautiful job. It really looks clean and nice like factory. They gave me a very quick turn around, less than a week. This was my first dealing with them but I'm pretty certain it won't be my last. I'd send another off to them without reservation.

Ok guys, apoligies up front for this question. What exactly does porting do? What is the benefit(s)?

It redirects some of the gases and pressures from a fired round upwards to alleviate some of the muzzle flip. To a new shooter it will feel like less felt recoil. For small guns it's especially beneficial to cut down on the muzzle flip. I'll perhap be able to provide more useful info once I shoot my K40. It had a pretty sharp jolt on firing, nothing brutal but more than I like, hopefully porting will tame it a bit and help speed up follow up shots.
Just makes a gun more comfortable to shoot basically. They advertise that is has no adverse impact on velocity or accuracy etc.

magna port.com it will give you a much better explanation that I can. I can say without a doubt it makes my guns all feel less recoil and the second shot is right there waiting on me to pull the trigger. bigger the caliber, certainly the more magna porting helps. All my 9's are mag na ported ...

Probably not needed on a 9mm gun, certainly works great on 40 cal. :behindsofa:

Redirecting a small portion of the expanding gas so it moves vertically will generate an upward force. Since all actions have an equal and opposite reaction, a similar downward force is exerted on the barrel, which will help to lower to total upward force imparted by the rotation of the gun around your wrist.

is going to grow hair if you don't get off ur arse and get out and shoot it. those ported holes will close up just like "well I won't go any further". get out and shoot that gun Bawanna, or I an a few orthers will head down and do it for you.:4:

I'm hoping to really I am. With Ma's day this weekend I'm not sure it's gonna happen but she is rather ticked at me so could happen. Now I'm kind of hoping to light Tiny off for a maiden voyage along with the K40. You fella's come on over though, we can have a good ole time. Shall I make reservations at the Holiday Inn or you gonna bunk with us?
You can park your hog in the garage if you put papers under it and clean up after it. I'll try hard not to put any of them girly man tassles on the handle grips for ya even though I really want to.

Makes absolute sense. Thanks!

[jmstallard]

Whoops, "upward force imparted by the rotation of the gun around your wrist" is actually incorrect. It's a rotational force.

It's a bit like thrusters on a boat, some of the explosive blast (hey, I know it's a "push") is directed out the holes upward, counteracting the muzzle flip and a bit of the recoil affect, since not all of it is going out the front anymore.
You do have another thing to be careful of now... like the gap between the forcing cone and front of the cylinder of a revolver, you have redirected muzzle blast coming out and upward which could be a bad thing in Close Quarters! If you're tussling with someone and wind up firing it in a way that the blast strikes you... not so good. On titanium/Scandium framed revolvers, S&W puts a stainless "clip" between the forcing cone of the barrel and the topstrap just above the barrel... because repeated blasts there can "cut" though the titanium... which is pretty hard stuff, but evidently SS is more durable in that case.

Did you see the Mythbusters show where they tested the story about a guy shooting a S&W 500 .50 cal revolver....He tried to grip it to far forward on the frame and got his thumb too close to the forcing cone cylinder gap and the gas cut his thumb off.....The Mythbusters model hand test showed it very well could happen!!!...:eek:...I still don't see why anyone would want to shoot one of those cannons unless Godzilla was after you.....:2eek:

[jmstallard]

Given that heavier bullets require more barrel length to reach full velocity, let's say my bullet hits the ported portion before it has reached full velocity. Is enough gas bled off that muzzle velocity will be lessened? It's easy enough to test if you have a chronometer, so maybe someone here has done it, or knows someone who did..?

[wyntrout]

Supposedly, there's "negligible loss"... whatever that is. That's what they always say.:D

I've seen the flash/bloom around one of those .500s or .460s for that matter, on YouTube... about the size of a bathtub!!! :eek: I wouldn't want to fire one holding it correctly, let alone like some of those idiots do, especially the ones letting their girlfriends knock them selves silly limp-wristing those things.

claims no more than around 6% muzzle velocity could be lost on most guns. One can make this a big deal or not, one has to weigh the factors of the benefits and the fact of the caliber of gun he is trying to tame down. I loved Magna ported guns, that being said I shoot 9mm's and they are not know to be a hand punishing caliber like maybe a PM40 over a PM9. There are IMO benefits to magna porting the bigger calibers, revolvers are no different either. It does work. I do for some reason feel the porting work that mag na port does works better than just round holes.

We have read here and there on kahr forums of guys magna porting their 40 cal kahrs and reporting great results, much tamer to shoot, second shot much better to..

Just remember once holes are drilled or cuts made, u can't go back without substantial cost. Some I know have just replaced the barrel and left the slide cuts there, which actually is not a big thing, as it does lighten up the gun somewhat.
I also don't think it is a mod that you can recoup your cost out of later on either. If you port it, keep it and just shoot it like you stole it..

That settles it. Magna-port here I come. Unfortunately it will have to wait until after my Vegas trip with the wife. If things go horribly south then I may be selling off a few...lol

Stay positive pal, if things go well you might own MagnaPort and offer discounts to us mere mortals.
Remember what happens in Vegas stays in Vegas except you could PM me some of the finer details. OR NOT.

I happen to like that cannon, even if I can't afford it. That's what he gets for not making sure all was right before lighting that beast off...
