It's not as simple as just putting a comp on and it runs just fine. First off, factory ammo really isn't going to work the comp with the proper gasses. You need to tune your loads for the comp to get it to work efficiently. You also have to tune your recoil springs to run your gun due to the comp.
I run a compensated Glock 34. My loads are 1.5grs above book max using Auto-Comp to get the desired result of minimal dot movement. I have to run that much powder to make enough gas to run the comp. I also had to change the recoil spring to an 11lb spring so that the slide would run. I am running a 124gr bullet at over 1250fps and making 156 power factor. If I were to remove the comp and run the same loads, I would have to put a heavier than factory power recoil spring in to keep from beating the gun up.

 

I always see guys on YouTube and Instagram adding comps to their guns and they never talk about changing loads or recoil springs. I thought it was just a bolt on and go part?

It is not that simple you are adding weight and reducing recoil forces so you need to tune it to work properly.

I have the AW comp on my G20. Like has been stated above me,you'll more than likely have to change your recoil spring. Especially if you're going to run off the shelf ammo.

I actually use a higher than stock spring in mine (24#),but I'm shooting some pretty hot handloads. The only reason I have the comp,is to keep my brass within walking distance.

 

I Mag-na-ported my Super Redhawk. What a difference. And no add ons. But I didn't compete with it, only hunted. http://www.magnaport.com/hgun.html

 

That's a revolver. There aren't as many moving parts to worry about.

 

Compensators are for competition, not looks. They have a precise bore that must be threaded on to maintain alignment. No comp that slips on and is held with a set screw is functional, it's like a fake suppressor. Most factory ammo won't function correctly with a comp. It takes very hot loads and tuned springs to cycle just right. Porting is not compensation. There is no real reason to comp a 9mm or a 40S&W for standard factory loads unless you are going to run USPSA Open Division. There is only a small reduction in recoil and most all shooters would be better off to use the proper grip to manage recoil.

For a 9mm Glock, Open Major means a 125 grain bullet going over 1,320 fps, otherwise it is Minor (125 vs 165). Shooting Open Minor sucks because it is Major scoring. Might as well take the comp off and shoot Carry Optics, which is scored Minor.

The only ones I see in competition, that work, are Carver Custom and Jager.

My logic exactly. I picked the Walther Q5 for the poor man's open division...:supergrin:

 

Go here for after market parts.

Grip harder.

 

How would the recs you get on this forum mean anything because most guys can only tell you about the one they spent money on and installed, certainly not compared with the various choices out there. Additionally everyone has a different level of experience and 'sensitivity" to recoil, and skill at follow up shots.

Even a professional master competitor's input would have no reality in your application.

Who is a professional master competitor? Are you referring to a paid professional USPSA Grand Master like Rob Leatham? But if you actually shot USPSA/IDPA/Steel Challenge/3 gun, then you would know....

 

..... They have a precise bore that must be threaded on to maintain alignment. No comp that slips on and is held with a set screw is functional, it's like a fake suppressor. .......

Neither of the comps the OP noted are "slip-on", they are threaded and use a set screw to keep the proper orientation.

Duh...

Yeah...Those guys with all the sponsor patches, and think they know it all because they compete, and never fail to mention such in each of their posts.

Actually I meant the Grand Masters...I don't think they need "compensators" For the rest of us who don't shoot 10K rounds a month, the difference between one muzzle device and another may just be bias because of price or sound produced.

 

I don't think they lurk here. Bluntly, I think you are asking this question to a bunch of internet Glock specialists, many who put things on their guns for appearance, and brand recognition.

 

^^^^ Your'e right about that. I'm always amused by the newbies who change out everything on their new (first ever) Glock and then wonder why it doesn't run right. First order of business for any gun, new or used, Glock or not, is to function fire it. Then, if you must have, other than better sights, only change one part at a time, function firing in between.

 

I always see guys on YouTube and Instagram...

Stop there. Many idiots in both places show themselves eating laundry detergent.

 

PM member es350, he has more compensator knowledge than anyone else on these boards.

He actually makes his own. He can tell you how to set the gun up, where to get the best comp, etc.

He is a great guy t boot.

Good luck.

 

Thanks Willy,

While I am not a competition shooter "grand master" I have played around with how flat I could make a gun shoot.

As others have mentioned, it is a complete package for the ultimate flat shooting gun of gun, brake, load and recoil spring.
What most don't realize .... if shooting factory ammo or loads not producing enough gas to make a certian brake "work" then you need a more efficient brake design to harness all the gas produced with the loads you are shooting.

# of ports/baffles , size and location all effect how much gas is needed/how effective a brake is with a certain amount of gas put into brake.

As far as a brake not being effective with "factory" ammo.... then you need to shoot my gun and see if you say the same after.

Could you please elaborate on # of ports / baffles , size location , caliber/pressures on compensators . Would appreciate some insight . I have made several . They all work , but I always wonder if I could have done something better . I 100% agree with brake , load and recoil spring . Thank you

 

I use the Rock your Glock comp in my g22 with 357 sig threaded barrel shooting minute man Ammo 125 grain gold dot 1600 FPS 725 ftlbs energy this thing tames it big time
2 ports on top 2 on each side

I have the Parker Mountain Machine single port comp with a SilencerCo barrel on my G45 and also their double port with their in-house barrel on my G45 MOS.

They both run flawless with 115 grain ammo without any needs to change springs, have specific loads, etc.

I personally wouldn’t comp anything longer than a G19 sized slide tho... In my opinion, that is the sweet spot and ideal size to comp for both functionality and aesthetically.
