Do you use 3 prong adapters for .22's also? I thought they used direct screw on.
Most are direct thread.

Not tapered. I do keep a glove to tighten up if shooting high volume. Never tried Teflon tape or Blue Locktite.

I like to standardize my mounts to keep out of trouble. 22 cans are usually DT, not enough room for a HK standard 3 lug. Some have used proprietary QD connectors, but they get expensive if you have a lot of hosts. 22 like any DT can come loose unless it's beyond hand tight, but stays cool enough that it takes a lot of rounds, and you can usually check it every couple boxes. I run 3 lug on fixed barrel pistol cal, and Griffin taper mount on Rifles. Helps keep me from throwing a 9mm through a 30cal can. On my AR22s I use a muzzle device as a thread protector, can use nitrile O-rings to clock them and keep them tight. I use KAK flash cans in stuff with long handguards, they have notches you can tighten with most anything to keep from coming loose

[EDIT]
So my Walther PPK/S 380 (e.g.) does not need a booster. Hmmm. No threaded barrel though.
The piston in the booster allows pressure to essentially blow the can forward aggainst the spring and uncouple from the barrel. In a fixed barrel it just blows forward and beats the hell out of the mount and spring. With 3 lug the pressure actually tightens up the mount and seals the taper as the can builds pressure, so kinda the opposite. Rifle cals get too hot and will wreck the spring, and damage either enough to get a baffle strike in a few rounds.

Snug it up tight and 22 can go a couple hundred rounds, 9mm or rifle cal need to be torqued if DT or they come loose constantly.. I don't use anything on the threads, just keep them clean

In a 9mm can, There are 3 that kinda stand out, Silencerco 36M, Dead Air Wolfman, and the Rugged Obsidian 9. Main thing they all share is modular length, and they are all excellent PCC cans that can handle some (or many) rifle cals. A short 5" K can is really nice on short braced pistols or SBRs, or even handguns, and the ability to add an extension to quiet it down more is convenient. While all 3 have 3 lug setups, the Wolfman and 36M can handle full power rifle rounds, and the heat will destroy a 3 lug mount, so you would need another mounting method to get the full versatility out of them.[/QUOTE]



I currently shoot my 300 BO cast loads (150gn PC bullets at 1900-2000) FPS from my 16 inch barrel. I haven't Cronied my 8" pistol yet but I'm guessing that they would probably be in the 1100-1200 realm. So for these I would need to get a different type of adapter than a three prong or an adapter to change the threads from 1/2x28 to 5/8x 36 or whatever my 300BO's are threaded. Am I correct?

300BO subs are borderline, pretty much the hottest thing a 3 lug can handle. 300 supers run too hot and need a rifle rated mount. The main risk is the spring gets cooked, if it has O ring they get burned and the can will get play and can strike a baffle. The Wolfman can use the keymo micro or 3rd party stuff like Griffin Plan A / taper mount. The 36M comes with an ASR mount for rifle cal, would need to add a lug kit to both cans. Could run DT, but it needs to be torqued or it will come loose every mag. Keymo is really nice, kinda like a rifle rated 3 lug, just slide on and turn. Problem is it's expensive, heavy and adds length. I like Griffin taper mounts, lots to choose from, simple, well made and they just work.

Thanks again, I will start looking for Griffin taper mounts.

Theses are Griffin's current taper mounts, you have DT adapters, linear comps, 3 prong flash hiders, the mild hammer brake and the aggressive paladin brake. Most rifle suppressor mounts use a taper to center the can and threads to tighten it. Some like the Sico ASR add a locking device, but tapers have enough surface area to increase friction, and they tend to get tighter as they heat up, not loose like DT mounts, so you generally don't need a redundant lock for them. I just snug my Griffin stuff hand tight, and they NEVER come loose when firing, in fact they might be so tight if still warm that I either need to let it cool, or use a strap wrench to remove it. The Griffin system is light, generally mounts inside cans instead of in a mount sticking out the back, and probably has the best muzzle device selection. They also have a gate-lock system that locks in the groove of standard muzzle devices, provided the device is shimmed and concentric. Some don't like the threads being forward of the sealing taper, but they won't get crudded up to the point a can won't come off, and per Griffin a clean taper to keep it concentric and locked is more important than clean threads. To use it simply screw the can about 3 turns till snug, and that is is, no need to access the mount, so it works inside handguards.

https://www.griffinarmament.com/acce...uzzle-devices/

The DA Keymo is pretty cool, slide the can on, turn or two to tighten and that is it, the ratchet teeth and spring lock it, and won't come loose. It's heavy, expensive, and adds 3/4" to the length of a can, but can work inside handguards. THe new DA Xeno system is similar to Griffin's, but the taper is in front of the threads.

https://deadairsilencers.com/product...s-accessories/

The old standard ASR got popular because it used a variety of adapters that could be used in 3rd party cans, so you could use several cans without swapping muzzle devices around. It has a taper and coarse threads like the Griffin, but has a lock ring you turn. It's redundant, it's cumbersome, and you need to access it, so it can't be under a handguard

https://silencerco.com/shop/accessories/platforms/rifle

The Q plan B, is similar to The Griffin plan-A, threads and a taper mount, but they have all of 3 muzzle devices.

https://www.liveqordie.com/collections/muzzle-devices/

Most of the rest are proprietary, OSS and rugged don't have mounts that can thread into other brands, some oth the others like YHM are similar to others, or just never really caught on.

Just ordered a Rugged Obsidian 9 from SS. They are backordered but at least I am in line.

A downside to something other than direct thread is the price adds up and the cans are almost always heavier. Usually just an ounce or two, but then the weight of the muzzle device is on there also. So in the end you are taking usually 4-8oz more weight compared to a DT.

Upside is usually faster and certainly more secure mount.

Also cost. If you only have a couple guns to mount it to, no problem. If you’ve got 10 guns, that is 10 times probably $60-110 per mount. That’s a LOT of extra cost.

That’s largely why I prefer direct thread. I am not worried about swapping quickly. Yes you do have to check if it is coming loose every couple of few magazines. You’ll get a feel for it. Yes you absolutely must have a mitt or glove laying around unless you are only putting a few shots through it. Think how hot a barrel can get. Now times about 3 or 4 as the fan is collecting all those hot gasses. A couple shots isn’t a big deal, but a dozen .308 through it and the can is absolutely not safe to touch. Let alone running a few mags through it.
