Threaded Pistol Barrels

[giggitygiggity]

I am about to buy some threaded barrels for my pistols. I will be using the SWR/Silencerco Octane 45HD and Octane 9HD2.

I have a Beretta 92FS. With the Octane 9HD2, can I simply send in the factory barrel and have it threaded 1/2x28 or do I need to buy a completely new threaded barrel? I only ask because I am not sure if the Beretta 92FS threaded barrels need to be longer than the standard barrels. How about for the Beretta 96?

I will also be suppressing the following:
-Beretta 92FS
-Beretta 96D Brigadier
-Glock 21 Gen3
-Glock 30 Gen3
-Glock 37 Gen3
-H&K 40C
-Sig P226 9mm
-Sig P220

Please let me know if you have suggestions on the barrels that I should get or any dos/don'ts that you have. Thanks.

Tornado technologies provides factory 92 barrels threaded in 1/2x28 or 13.5mmx1LH. Link above is to the choices.

In my opinion Lone Wolf is the best choice for your Glocks. At some point I want to do my barretta as well but have done zero research to date.

When possible, it's usually best to buy a factory threaded barrel in my opinion. However, some gun makers don't offer factory threaded barrels, or they only offer them for a few select models. So, in that case, aftermarket threaded barrels from companies like Storm Lake, KKM, Jarvis, and Lone Wolf are your best option.

Keep in mind that some factory barrels (like Glock's) only come in left-hand metric threads, whereas aftermarket barrels are usually offered in both regular right-hand threads and left-hand metric threads as well. Luckily, Silencerco offers replacement pistons in pretty much every thread pattern you're going to find.

For some pistols, there are no factory or aftermarket threaded barrels to be found. In that case, companies like Tornado Technologies can thread your current barrel. But because very few un-threaded pistol barrels are long enough to be threaded, they need to add an extra piece of barrel to make it long enough before they thread it. And therefore it's never going to be quite as strong as a barrel that was already long enough to begin with.

In my opinion, the Beretta 92's barrel isn't long enough for a suppressor to mount solidly enough without extending the barrel. I know many companies will just thread the end of a standard 92 barrel and it works fine, but I wouldn't feel comfortable mounting my suppressor on threads that short. Most suppressor companies recommend at least a .4" thread length for standard 1/2x28 9mm threads, and the 92's barrel doesn't extend that far.

Yes but these add about $70-80 to the "cost" of your threaded barrel. Best to get barrels threaded to match the most common right hand threading: 1/2x28 for 9mm, 9/16x24 for .40S&W, and 0.578x28 for .45ACP.

I agree. I was just pointing out that if he wanted a factory threaded barrel that only came in left-hand metric threads, Silencerco makes a piston for it.

One of these days I'm going to buy a Glock 19 factory threaded barrel, even though I'll need a new piston and it's going to screw on the wrong way from what I'm used to. It's too bad they're not making them at the moment so they're hard to find and pretty expensive.

Why? What makes it "best?"

Lowest cost, more than good enough for most purposes. Would be my bet.

I've both Lone Wolf and Storm Lake barrels. I see nothing in the SL barrels to justify the ~50% extra cost other than they have them for pistols Lone Wolf doesn't.

Threading a 92 barrel

Adco does a great job with threading Beretta 92 barrels. You have to send the slide in with it. Total cost is about what a Lone Wolf Glock barrel runs. The m9 variant pistols run great with cans but are a huge package. A. Glock 27 with a LW 9mm conversion barrel is a sweet host and a versatile option with mag grip fillers and 357 sig conversion barrels.

As to thread engagement the can indexes on the barrel shoulder and 3 threads can handle full torque. A .330 long 1/2 x 28 thread on a M9 will support a can fine if it is kept tight. Bring an oven mitt and check often.

I go with EFK extended threaded, but they usually run about 300usd.

Of the three makers of drop in Glock barrels, Lone Wolf has the best full chamber support and are just as good as far as accuracy and fit and finish as the more expensive options. Also if they don't offer what you want (like an extra long 10mm threaded barrel for my Roni or a threaded version of their 10mm-to-40 S&W conversion barrel), their custom shop will make it for a reasonable charge and fast turnaround.
