I would have to build one up for you. Don't know when I'll have time.

Have you tried putting a spacer in the back like 9mm 1911 mags do?

New Shop is getting up and running (slow and steady). Working on followers for the TCM mags. Got to make some adjustments to make to make the TCM run like the 357 ARMags.

Had a good day at the shop today. Cut some steel and worked on the TCM mag set up. I was trying to solve three problems at once and finally got fed up not making progress so I just tried to solve one. It looks like its working but will do some tweaking this week and hopefully will have some beta's to test this weekend at the range.

Got 3 TCM mags ready to go for live fire testing this weekend and a variety of loads from the 9R's to 1.38" oal. Hand cycling was OK, but not like the real thing.

Cut parts for the TCM mag with BHO tonight and the dang thing actually worked. Got some tweaking to do with the follower, trying to make the 357/TCM work with the same follower as the M1 carbine with its smaller dia case.
Its nice to have the shop close at hand.....

Had a full day at the shop today and tweaked on the BHO for the TCM mag. Need to work on updating my drawings from my scratch pad notes and will see how testing goes tomorrow. Did a run of barrels last week so will run them through testing tomorrow and see how the mags shake out. Weather is supposed to be dry but turkey season is open so ...... hope I don't piss off too many hunters.....

Good trip to the range with the new TCM mag set ups. While not perfect, operation was well above 80%. Nose high jams was the only failure to feeds that we had and we can pretty much predict what mags have that issue. Had some reload issues we need to track down with some very hot loads so we cut testing short. This is the first time this has happened so we need to dig into what happened there. We got some new brass in and most loads used it and these weren't max loads at all, just function testing loads... Bottom line, std TCM rounds feed from the new mags for the most part, with Bolt Hold Open.

tested Tokarev and 10mm out of the new AR mags yesterday. Toks fed better, so will review the data and see what tweaking we need for the 10mm

Worked on the 10mm feed with the new mags and made some good headway. Lots of comparison with things that work and don't to see how we can feed multiple sizes of rounds from a common body, follower, ramp. Too much to ask for, but making things better is always good. Hopefully I can get some more time in on these long overdue changes...

Got a bunch of work done on the next batch of Beta TCM mags. Going to be on the road all week so won't get any testing in. Solid model for the follower is underway so we can start getting them molded when we freeze the design.

Did you ever figure out how to adapt m1 carbine magazines to feed factory 22 tcm reliably?
