Quoted: Will .578-28 threads leave sufficient barrel wall thickness .578 is standard threading for 45, even on MG's, no issue |

The Lage .45 uppers that are not threaded for traditional MAC silencers are threaded .578x28. You shouldn’t have a problem.

Quote HistoryQuoted: .578 is standard threading for 45, even on MG's, no issue But I'm using a Griffin .578 3 lug adapter. The CMMG RDB .45 barrels also come w/ .578x28. On my .45 UZI's I use a barrel nut suppressor although I wouldn't hesitate to use a .578x28 on the UZI.   |

Thanks amphibian.
I reached out to Joe at Curtis Tactical about making a .45 version of the CT9KS, CT9K, or maybe something in between in length. I'm wondering if the KS might be a bit short for the larger .45 bore. Still waiting to hear back from him, but if he ultimately undertakes the project, I'd like to use that suppressor in a 3-lug setup for .45 Uzi and Mac-10 use with some secondary 9mm use as well. |

Don't know if you have seen this
 Suppressed Grease Gun Submachine Gun - Teaser Video That was based on what I requested him to build for me.... I would presume the MK9K length in .45 would work well with his new design |

I have watched that and compared it pretty closely to your site. The baffle core seems to be pretty much the same thing as a CT9KS (6 baffle stack), but it also has the ported barrel and consequently an absolutely massive expansion chamber. It sounds great from what one can tell from a YouTube video, I just don’t know how much is attributed to the ported/integral design elements. I mentioned that video to Joe in my email and asked what he would recommend if my priority is on at-ear suppression and reduced gas to the face. We’ll see what he recommends. I don’t know if it is possible to split the difference (wanna say KS is 5.75” and K is 7.75”, so maybe go 6.75” if that is an option?).

One was the Gemtech UMP can which has the Uzi barrel nut mount and I have the one pictured below which is larger and quieter than the UMP re-core.  |

I meant to ask you if there was any reason you chose the Griffin 3-lug .45 pattern over Sico, Rugged, etc. I could be wrong, but my impression is that there is not really a true standard for .45 3-lug sizes, but I don't know if any of the aforementioned ones (or any other ones I didn't name) are any better than the rest. I'm hoping to get him to make me a .45 Bixler and a 9mm Bixler mount.

As you mentioned it isn't compatible. If you or anyone else is interested in it let me know.  My .45 Curtis Tactical re-core on my .40SW CMMG RDB. I really like how the nut is such a small diameter than other 3 lug mounts so it can go in most rails with only a slight amount of the 3 lug protruding.  |

I’ll admit I don’t fully understand how the Bixler mount works. Don’t you need access to the nut to install it? I’m curious how you can mount it in a semi-tucked configuration like that.

I heard back from Joe. He said that for the uses I described (primary .45 in a Lage Max 10 and Uzi; secondary 9mm use in Lage Max 10/31 and Uzi) he recommended a longer version (7.5") of the KS which would use the same baffles but it would just have more coaxial volume to cut down on blowback. He seemingly agreed the KS length was a little short for the larger .45 bore.

SICO pattern matches B&T's 3 lug in .45 ACP.
