Anyone interested ?

Many of you know me through this great forum and that I have been heavily involved with the .356 TSW cartridge.
Posting the many conversions that I have worked with, having great success and enjoying the testing and evaluation of this great round.

My retirement from Aerospace Machining with 30+ years experience in many, many types of manufacturing processes has benefited me a great deal in my “odd” endeavors.

I am now contemplating the development and manufacturing of drop-in/semi-drop-in replacement barrels for all of us that have been thinking how nice it would be to have the advantages of shooting the .40 S&W and .357 SIG from out 10XX series handguns.
The first “Test Run” would probably be a lot size of 25-50 of each barrel (depending on the demand?) to accommodate the two different calibers in the two different barrel lengths, 5.00” and 4.25” with retrospect to the 1006, 1026, 1046 and the 1066, 1076 and 1086.

Wolff Gun Springs has a variety of replacement springs to taylor the recoil impulse and brass ejection to your liking.

Wolff lists the stock spring for the 1006, 1026 and 1046 @ 18#’s
They show 14, 15, 16, 17, 18, 20, 22 and 24#’s

Also the stock spring for the 1066, 1076 and 1086 @ 17#’s
They show 14, 16, 17, 18, 19, 20, and 22#’s

I am hoping to start the development after the first of the year.

If this dream works out I would like to expand to the 4013 style and 40XX series with .357 SIG barrels.
But that would be a little ways away at this point.

Any and all feedback would be greatly appreciated.
