Here is a solution for Witness Jams in .40/10mm.

I've read quite a few threads about the EAA Witness on this board, so I think my fix might be able to help someone here. As a lot of people have found out, the 10mm and .40 S&W factory mags for the large frame Witness pistols are nothing short of awful.

My first solution worked, but it was a little more complicated than I liked. (It involved TZ-75 followers and modifying a Wolff spring.) It's taken me a while and several experiments, but I finally have a second, very simple solution that works even better.

If you replace the internals of a 10mm EAA Witness magazine with the follower and spring from a .45 ACP Mec-Gar Witness magazine or .38 Super Mec-Gar Witness magazine , then you can reliably feed .40 S&W or 10mm!

Mec-Gar uses a properly designed follower and a higher quality spring. That's all it takes to get these pistols working. The magazine body itself did not have to be modified.

Mine will even cycle 10mm, 175 grain Winchester Silvertips.

Magazine capacity was reduced in my pistol from 15 rounds to 14 rounds, however, now the Witness feeds without jamming.

It's a good idea to install an extra power firing pin spring in these pistols along with a more stout Wolff mainspring. Replacing the hammer spring also helps. I went from a 16 lbs to an 18 lbs for more reliable ignition.

Solution is also posted on the Witness board at CZ Forum:

Wow. Flame alert. I think you were probably looking for one of the Sig vs. HK vs. Glock posts on the board? (My preference is with my Glock.)

Anyway, just trying to help. Sorry if you're offended by Tanfoglios!

I think this is the first post on a gun forum that I've read since forums were invented where a man posted a helpful solution to an experienced problem without waiting for the question to be asked.

I am impressed! I think this is what the forum is partly for, information on working solutions to problems encountered.

small note

My 45 Witness mags work without fail in my 45 Witness. And have for fifteen years.
When I'd installed a 38 Super top on that frame and used EAA 38 Super mags, that, too, was utterly flawless.

But I shoot 40 S&W through my small-frame Witnesses with the Witness 10-rd mags, and they work perfectly, too.
And also 41 AE and 9x19 and 9x21.....

Yes, I'm a EAA/Tanfoglio believer. Since 1994.

(Odd that Tanfoglio is a highly popular firearm in Israel?)
