Barrel Porting - Worth It?

You would need to have the slide ported, as well.

 

If the pistol is going to be a range toy then porting would be fine, but really unnecessary in 9mm imo. If it's ever going to be used as a defensive pistol I would caution against it. In fact, you could not give me a pistol that was ported if I were going to use it in a defensive situation. Hot gas and particulates get ejected out of the porting at high speed. While that isn't an issue at the range where the pistol is held at arms length all the time, and you have eye protection, it's quite different if used defensively because it may be held close to the body in some situations, under the line of sight and you may not be wearing eye protection at the time. A face/eyes full of hot gas and particulates is not a good thing at any time, particularly not in a defensive shooting.

 

Really? I had never noticed from looking at the pictures of the newer 34. Does the Gen 5 G34 use the same recoil spring as the 17? I'd be curious as to slide weight difference. I thought that is why they did the cutout on the Gen 3 & 4 guns.

Sounds like a lot of gunsmithing to me. I'd keep it stock.

 

A waste of money

 

Some swear by it, others laugh at them. If you think it's worth it then you can buy a secondary barrel for about $100.00.

 

Yes, the RSA is the same for the Gen5 G34 and Gen5 G17.

I've had ported firearms. I would never do it again. YMMV
Very messy with gas and debris (gun powder etc.). The perceived "recoil reduction" was not worth it for me.

 

You don't need to port a 9mm. You need to get the proper grip to manage recoil, even a .22LR, that's all. Hold you gun like this. Not a death grip, just hold it.



or hold it loose as hell, like me. It still works.

I had a 23c once. Loud, dirty, adios.

 

Rock your Glock C comp porting on my G 40 and G 43 and previously on my 27 I sold. I like the results. YMMV

 

You say you have a good grip and that muzzle rise is minimal. What do you expect to gain? It's your money and your pistol, so if it's just for jollies, fine, but you are probably going to be disappointed.

 

Placebo effect is strong.
A louder muffler on your car makes it seem like more power--- 5-10% more HP guaranteed! Changing springs, rods, and adding doo-dads on the pistol makes it seem "better"-- but in ways hard to measure, but many will still swear and testify to their choices.

This bears repeating and amplification. I’ve seen this with ported pistols when shooting from weapon retention positions. A little bit of copper or lead up the nose can be a bloody mess. Just FYI, improperly timed revolvers can do something similar if they’re shaving lead or have an unacceptable cylinder gap.

 

I've got a 20c and really like the way it works with the 10mm cartridge. I'm not sure on a 9mm if it would be worth the effort. It might be easier to just buy a C model with the comp/porting already done. To each their own.

 

Porting is for bowling pin shooters.

 

G34 is already about as low recoil as a polymer pistol gets. I can’t see how porting the barrel will make much of a difference

 

A USPSA shooter with a ported Glock (Why? It put him in Open with none of the other advantages of a race gun.) had very weak cycling and many malfunctions with cheap ammo. His gun without superfluous holes shot the same stuff reliably.

 

Though I agree the G34 doesn't need to be ported to shoot it fast, when trying to reduce muzzle flip, every little bit helps. If I were going to port a G34, I'd have it done EXACTLY like the OEM G19c. Also, I'd have the ports as close to the muzzle as possible...not so much for more fps (though it helps, some), but for more leverage. 9mm is a bit weak, so the closer to the muzzle end of the barrel, the better the ports work, and the few fps gained also aids in more pressure to the ports. The downside to ports as far forward as possible is some of that extra leverage gets from the barrel to the slide. It may disrupt cycling. You'd have to keep that area lubed with a high temp syn grease and it'll get dirty, fast. If you clean it after every range session or every couple hundred rounds, you'd be ok. If you can't find someone to do it like the G19c, but closer to the muzzle, I'd pass.

 

waste of money, entirely unnecessary.
