I tried searching couldn't find much, if it has been discussed before then I apologize. The question is, is all I have to do is drop in a threaded barrel and if so who makes a good barrel? I have looked at lone wolf and they seem ok but are there any others I should look at? I have a H.E.M.S. 2 and would like to put it on my 21 SF. Also anyone make any taller sights to clear the suppressor or just point and shoot.
Thanks for any info.
 
Re: Suppressing a Glock 21

I was told that Glock offers a longer barrel for threading purposes but my information could be wrong. I would check with them.

For the sights,
brownells for Hienes
dawson precision for fiber optic front with adjustable rear
Ameriglo sights

Very good barrels. Glock 21 is on the list.

Enjoy. </div></div>

Is this the best way to go and are taller sights available?

Thanks
 
Re: Suppressing a Glock 21

Sight height is a function of suppressor design. And an after-market threaded barrel is a great option, you can go back to the stock barrel whenever you want.

I am not a Glock guy so cannot be of much help in Glock-specific areas, but storm lake barrels are quite good.
 
Re: Suppressing a Glock 21

Lone wolf is great for the price. All others will work too, just at a higher price. As far as sights goes, Ameriglo has great high night sights you can see on their site. LPA is another good choice if you want to have adjustable highs.

Lone Wolf is not a great barrel, it is a fair barrel at best. WIll they work, yes on some hosts and with some cans. I have personally seen enough out of spec barrels (and far far worse) from them to never use them. I know gunsmiths that when suppressed Glocks come in with troubles and they have LW barrels, well, start by throwing the barrel out. Those barrels can crap out a slide faster than you would imagine. I use some of their products, but not their barrels.

Much better? Godness yes, much better is out there. My two favorites are Stormlake and Bar-Sto. Spend the money and do it better.

Sights cut two ways, many/most sight right through the can and do just fine. Others use high sites from here:

See bottom of the page. I use their sights, great but know you will definately need a taller rear tool than the standard Glock.

That's interesting because if truly defective LWD will replace it free:

"Lone Wolf Distributors will replace any of our barrels or barrel accessories which are found to have manufacturing or material defects".

Also how does the barrel "crap" out a Glock slide exactly?
I have a couple LWD barrels and they are decent for the intended purpose (launching lead quietly). YMMV.
 
Re: Suppressing a Glock 21

Of course they will send along as many as you want, that is not my point. Some refuse to use them.
They want barrels in spec. As far as damage, out of spec barrels with locking lugs out of spec, etc. cause lock-up rounding wear, slide slap at top, bushing/end slide dimension wear, you name it. On any pistol, a balancing act exists between the Neilson device and the barrel. Most cans actually overcompensate with their Neilsons to insure cycling. In other words, the Neilson doesn't really float the barrel, but provides for an over active slide kick. A sloppy barrel, one that isn't really in spec, hardened properly takes it all out on the slide, banging into and out of action and slapping through the slide. That can on the end that is supposed to be weightless, isn't, and its highly leveraged weight takes a toll on the slide.

If the question is "are there better barrels than LW, IMO the answer is hell yes"

Like everything else, you get what you pay for. Get a decent barrel, absolutely essential for some models of Glock.

Do you think drop in is great? Why do you think most of the better barrel houses sell semi drop in? Do you think they can't finish their barrels themselves? Do you think these guys don;t know there is somebody out there selling barrels at less than 50% off?

Get your barrel fitted, especially for a suppressed Glock. Just because your suppressed Glock runs with a cheap barrel isn't always goodness.

Well a manufacture part is either in spec or not hence the interchangeable nature of components. You lost me referring to locking lugs and Glock in the same sentence.
1911= lugs
Glock=locking surface.

Bar-sto offeres a semi-drop in barrel which is similar-

"A SEMI DROP IN Barrel Generally requires little to no fitting. They should go in about 7 out of 10 times with no fitting required but with the tolerance of firearms, this is not always the case."

Same for Storm Lake-

"QuestioN:
What is the difference between drop-in and oversize?
answer:
A drop-in barrel can typically be installed by the user with little to no fitting. Glock part tolerances are generally held quite well, and as a result will almost always allow for an easy drop-in. Some firearm tolerances are not held as well. As a result, the barrels we sell for these models must be designated as semi drop-in barrel and may occasionally require the aid of a gunsmith. All drop-in and semi drop-in Storm Lake Barrels are manufactured with the intent to provide the closest tolerance lock up for best accuracy while allowing for the least amount of required fitting. If your purchased barrel does not drop in, we recommend that you take the product to an experienced gunsmith to fit it. Please note that we cannot accept returns on barrels which have been modified."


If you want a fitted barrel that's great. After shooting bulleseye 1911's I have gotten away from over tight pistols (Barrels, bushings, slides) in favor of reliability and easy of disassemble and parts interchangeability.

I had a couple Bar-Sto barrels on my bulleseye guns and they are top notch. I do think its overkill for suppressor use on a combat intended pistol.

Its all good.


 
Re: Suppressing a Glock 21

If you can, the people that made the suppressor. Is it is done properly, and the Neilson device will allow for it in its design, the suppressor can be set "on ears" allowing for single action operation as well. In other words, "on ears" will not allow the slide to cycle, eliminating the action noise. Add blast suppression, sub sonic flight signature, and no action noise and you have as quiet as it gets. You can switch from normal semi operation to no action with a twist of the wrist.

Best of luck.

Re: Suppressing a Glock 21

I have owned several lone wolf barrels...all worked great..

i have had some Bar sto barrels and it looked like agrade school made them with a file.

Lone Wolf you will do just fine. Works with HEMS II and the Osprey

No doubt, here they are at recess...the files are kept in the CNCs in the back...

Seriously, your point is well taken. Since Sr.'s death, there has been a subsanitive change in the Bar-Sto finish. But, the metalurgy and the hardening (hard and hard) is so far superior to LW that they are in different leagues. For many, they won't live with the "loose fit" of "drop it" especially when they hang a can on the end. Few understand that the contact points change when you add the weight of a can, refit should be done. Anybody that owns a suppressed rig knows the marking and wear occur at different points.

So :

1. To get a tight, proper fit, one that can wear and not go loose (what happens with most drop ins) means the surfaces are going to be addressed anyway. What one is left with is great steel and best hardening. The "it looks like crap" goes with the material. But, as you said "file marks" prior to being finished.

2. All the "internals" chamber/rifling are some of the best out there.

Bar-Sto makes the best, most perfect Colt barrels, period. When finished. their Glocks are superb (see above).
KKM precision makes the best, most perfect Glock barrels, period.

Same here.

The "better hardening" mentioned on the bar-sto commercial got me thinking. I will have to take my LWD barrel to work and test the hardness out of curiosity.
 
Re: Suppressing a Glock 21

No offense to bar-sto...it's been a long time since I ordered

In my opinion the barrels I ordered

Took way too long fit and finish there was much to be desired they did shoot after substantial tweaking

These were for sig 229's
