Many have replied, BUT, some were not specific about model designation and caliber combination?
The first run is for both 5.00” and 4.25” 10XX series, ONLY 30 OF EACH, that’s it for the first run.
When their gone, their all gone.
The material/barrel blanks will be ordered Monday.

So, based on those that were specific, I was able to make some kind of tally, so far.
12 pcs. - .40 S&W for the 1006/1026/1046 Series
7 pcs. - .40 S&W for the 1066/1076/1086 Series

It’s still early for the .357 SIG, but based on this, I’m thinking it does not look like this is going to happen in any kind of quantity.
I would just order a couple .355 bore barrel blanks for the SIG and just make a few for myself,
it would be better making more of each, like I’m doing with the .40 S&W.

If I get a better response then the .357 SIG would be next.
8 pcs. - .357 SIG for the 1006/1026/1046 Series
2 pcs. - .357 SIG for the 1066/1076/1086 Series

After that maybe the .357 SIG for the 4006, 40XX series and a few for the 4013.
Although in doing a little more research 40XX series, there were multiple barrel part numbers for them also.
Also the 4013, I find that there were three different models and six different barrels.
You would have to either, send yours in or send a blueprint or describe in detail all the dimensions so I can compare mine as a reference.
Maybe in the future, with the help of the forum members that have the different barrels,
I can establish a data base and identify the different part numbers of each by a quick dimensional check.
5 pcs. - .357 SIG so far.

Please,
If you responded but were not specific, I need the specific detail about the model designation and caliber combination that you would be interested in.
PLEASE DO SO NOW.
You are not being held to it, I just need some kind of numbers to “shoot” for.
I have no fear that when they are all done that they will all go, this may only happen once in my lifetime.
I am expending quite allot of time and $$$$ with the reverse engineering of these and I do not want to disappoint anybody here.
