Looking for a good mounting solution for my Mojave 45 on fixed barrel .45 PCCs. Trying to decide between ez-lok, xeno xero, and .45 3-lug. All have pluses and minuses.

is the Mojave 45 HUB? My Mojave 9 is pseries and I think the 45 is also. I run the GA stuff on my LWRC but with the piston since it needs a booster and the GA mounts seems like the only thing that can make that work. I'm not clear how to run a fixed ezlok in pseries threads? I run Xeno on another gun because that was the combo I could find that worked for that situation. And I have lots of experience with .45 3 lug since my B&T's use it. My order of preference would be 3lug, xeno then GA. But all are usable. The problem I think for .45 3 lug is I don't know of a Pseries .45 3 lug adapter. I run the rugged .45 3lug on an Obsidian in my situation and that works great. I think practically you might be stuck with Xeno but I'm pretty happy with xeno. If you figure out some way for Pseries .45 3lug let me know as it would make buying a Mojave 45 for me a no brainer.

Ecco Machine makes an adapter that lets Sico mounts like their .45 3 lug adapter fit on P series cans. I believe that same adapter works with the GA 1.125x28 ez-lok hub adapter.
SiCo .45 3-lug with Ecco adapter. 3-lug muzzle devices look nice. The down side is the weight of the 3-lug adapter, plus the amount blast chamber volume the adapter and muzzle device takes up inside the Mojave.
P-series Xeno with Xeno Xero muzzle adapter. All DA components plus more free blast chamber volume than the 3-lug solution. My dislike is that the Xeno Xero is a bit big and ugly on the end of the muzzle.
EZ-lok direct adapter plus ECCO adapter. More minimalist than the Xeno Xero and similarly frees up blast chamber volume. Another plus is that I can run a GA carry comp when I’m not using the suppressor.This message has been edited. Last edited by: Dwill104,

Ecco machine to the rescue. I guess I knew that adapter existed but somewhat forgot about it. I ordered the Pseries to Hub version and decided that I wasn't excited about it for what I was doing at the time and never used it. But since you brought up aesthetics there is nothing that's as good on the end of a muzzle as a 3 lug. nothing else even close. Once you pass on that, it matters not. Myself if 3 lug wasn't the choice I would go Xeno as I noted above, but actually I don't think it matters much at that point except cost or if you expect to need a thread pitch that favors one over the other.

I ordered a GHM45, so I guess that’s going to drive me to 3-lug so I don’t have to change adapters on the Mojave.

GHM45,
Soon you will be a B&T addict like me. I see no downside to .45 3lug when you can get it for the can you want and I have had no issues across a bunch of different cans. Your Mojave conversion approach I'm waiting till you say its ok to order the suppressor.

LOL, I’m pretty sure this will be my only other B&T purchase, mostly because of the prices (especially for the .45 mags).
I’ve run the Mojave 45 using the ECCO machine adapter and SiCo 3 lug adapter on two different guns, both with SiCo 45 3 lug muzzle devices. Two weeks ago on a Kriss Vector and today on a Stribog SP45A3. Results were the same. The good is that the stack up was fine and checked out with an alignment rod. The bad was that the ECCO adapter started loosening from the can within a couple of rounds, and then it was very difficult to remove the can from the muzzle device.
For the first issue, I had cranked down attaching the ECCO adapter to the can, and it was tight before I started shooting, especially the second time after I experienced loosening the first time. Still, after half a mag, it was loose. It may be some sort of dissimilar metals/thermal expansion effect, or maybe the adapter isn’t screwing all the way down because I see a slight hairline gap between the flange on the adapter and the rear of the can. I don’t think it’s a thread length mismatch because a couple of the factory adapters I’ve tried have as threading as deep as the ECCO adapter, or maybe one thread deeper, and they fit flush. OTOH, the SiCo 3 lug adapter fit fine in the ECCO adapter and didn’t loosen, so it’s an issue with the interface with the Mojave.
The other issue is that after firing, it was very difficult to remove the can from the 3 lug muzzle device. Went on fine, and after firing, I could push and rotate to unlock, then I couldn’t pull it off. It was like some sort of stickiness between the outside of the muzzle device and the inside of the adapter that I’ve never experienced with any of my 9mm 3 lugs. Hot or cold, it didn’t seem to matter, and then once I did manage to pull it off, I could put in back on and take it off normally, until I fired it again. By using SiCo components for both the adapter and muzzle device, I was hoping to avoid any problems, but that didn’t seem to work out. To me, this is more of a problem than the ECCO adapter loosening, because I can probably use Rocksett or similar to keep it tight.
I won’t get my GHM45 until next week, and it will be interesting to see if it’s still sticky with the B&T 3 lug barrel.

Is the B&T .45 Glock mag lower no longer available. That's been my solution to the mag price issue on all the B&T product line. (note to self with all the P320 issue those mags should now be cheap and there is a 320 lower) Thanks for the update. should one just locktite that adapter to the can? as you note. I have occassionally experienced the sticky 3 lug. I don't know how many rounds we are discussing but on one of my clones I have to smack the can forward to get it off. I'm certain that some part of the 3 lug is not fully in spec.

Unfortunately, I haven’t found anyone selling just the .45 Glock lower; only complete guns with the lower, and not the GHMs.

I've been told specifically by B&T dealers the Glock Mag lower specifically for the .45 is NOT compatible with the B&T APC/GHM45 Mag Upper, and vice versa. That was the main reason the B&T APC.45 SD and GHM45 have been a non-starter for me. I am not spending a $130 for .45 stick mags, and the fact you can't buy the Glock lower for the two means it's not an option.

Well, that explains why I can’t find any Glock lowers. Oh well, it should be here tomorrow. Got a couple of extra mags and a pic rail adapter for the rear, but I don’t see spending much more money on it.
Getting back to EZ-Lok, I recently used it on my Obsidian 45 and SMG-45, and constantly had to retighten it. Very disappointing. Maybe it has something to do with the horizontally sliding barrel of the SMG-45, but I think I had better results just using the standard Rugged piston when I last shot it years ago.

Now I'm confused. Doesn't an SMG45 need a booster to run?

Yes, I was running it with the booster. GA makes pistons with EZ-Lok (and CAM-Lok) threading. That’s what the systems were designed for. You put the GA piston in your can’s booster housing and then attach it to the EZ-Lok muzzle device on your gun. GA makes pistons for Rugged, SiCo, DA, etc.

Sorry was still stuck on the OP about fixed barrels. This is literally the only good QD solution to the LWRC. It would suck if it doesn't work well!

Sorry for the bump. Paging Dwill104 to update on the LWRC situation, I am waiting to order parts that duplicate your situation and I would love some assurance that they will actually work as intended...

The components I used for the LWRC was
Rugged Obsidian 45 Rugged booster endcap and spring GA EZ Lok piston for Rugged GA .578x28 EZ Lok muzzle device
As far as working, the gun functioned fine suppressed. No failures. However, I had to retighten after about half a mag as it seemed to be coming loose which was unexpected because the taper mount is supposed to be better for retention than just a normal screw on piston. Was there anything else you wanted to know?
August 20, 2025, 10:19 PM
hrcjon
was wondering if you investigated the loosening and found any solutions. A half mag I would deem failure. Screw on is better than that...

No I haven’t. It’s a simple system, like all taper locks. I suppose I could try using the system with a different gun to see if it still comes loose, but that wouldn’t be for a while.

It's possible the taper was machined on the adapter to an incorrect angle. Taper mounts from smaller shops are susceptible to this. Wolfpack Armory sent out a bunch of Night Howler flash hiders 1 degree off on the taper. They wouldn't lock in Plan B mounts. Wolfpack quickly sorted the issue, so you might contact Griffin.

GA isn’t a small shop and I’ve never had a problem with the full size taper mounts coming loose. But, I’ll probably get another ez lok muzzle device when I can find one cheap or on sale, and then give it a try on a different PCC, and then go from there. It will probably be a while before I revisit this issue.
