I basically like the Tanfoglio/EAA Witness pistols, but EAA's support leaves lots to be desired. I'm having problems with my Witness 10mm which I believe to really be a problem with the magazines.
Here is a photo of the problem:
Here is a photo of how I believe the magazine "loses control" of the rounds once the mags get four or fewer rounds in them (although its most common on the last shot):
I'm already using the strongest magazine springs Wolff sells and have a 20lb recoil spring to try and reduce recoil frame impact forces. I've tried a 22lb recoil spring and it didn't cure the issue and I didn't like the way the gun handled, although I'd have stayed with it if had help keep the ejected brass where I could find it. Note how the round pushes thru the feed lips and points nose up, I believe with more than four rounds in the mag the force on the rear of the cartridges keeps the rounds from rotating nose up under recoil.
Shown on the left is the mag I "fixed" which had no failures last time out:
The mag on the right is stock, note the gap beyond the mag release point and how rearward the feedlip maximum contact is.
This next two photos show the tool I used to squeeze the feed lips together a bit (~0.013") and it in action on the magazine:
Of course once the lips have been squeezed together this much, the follower won't come up enough to lock back on the last shot. I filed the follower's sides to get it to lock back but it wasn't reliable locking back in shooting so I plan to build up the notch with JB weld to get it to lock back. I'll do a couple of more mags and test futher before I do the rest.
I slowly adjusted the amount of squeeze untill the lips remained it the position where I couldn't easily rotate the round up thru the feed lips like shown in the second photo.
Hope this might help someone else get these attractively priced guns running right.
