FIE TZ75 ISSUES AND PARTS

Question

I recently acquired an F.I.E. TZ 75. Is this the same as the EAA Witness Tanfoglio, or the CZ 75. Is there any interchangeability of parts among the F.I.E., EAA, and CZ 75. Are Armorors’ courses available for this?

Answer

There is an Armorer’s course, AGI #1314. Many of the parts can be adapted from one make to another, of the same configuration. Ken

Answer:

In the 1980’s before you could get the CZ75 guns in the USA, I bought a TZ75. After a couple of years of use, the firing pin retaining plate hammered the slot for it in the slide to the point that the firing pin retaining pin plate would no longer stay in the slide or retain the firing pin. At the time there were no parts available as FIE went out of business. I had to junk the gun. I think at the time the materials used in these guns was sub-standard. The current EAA imports from the same Italian manufacturer (today known as a Witness, and I have one in 45ACP) seem to be excellent guns without this materials problem.

The point is watch this FIE TZ75 closely as it may be a flawed gun. Anyone else have a problem with the TZ75 or was I just “lucky”?

Thanks for the “heads-up”. This one looks to have had very little use. I’ll likely install Wolff springs, including firing pin spring, just in case. Are you aware of a source for these parts? I may try to find an extra firing pin retainer, although I agree with you that the hammering of the slide receptacle is more likely a metallurgy problem.

Answer:

I would suspect that the Wolf springs for Brownells would fit since it is a CZ clone. The firing pin retaining plate was not the problem but it was the slide that got damaged. Only a spare slide would help that!

I looked at it at the time and could not see the physical mechanism that pounded the slide cut for that firing pin retaining plate. Recoil, it seems, would tend to push the plate against the bulk of the slide while just changing direction in its travel seems like it could not stress the cut in the slide sufficiently to make the metal break away from the slide to allow the retaining plate to fall off (??). I can not imagine that the firing pin spring could cause the problem (??). It was and is a mystery to me how and why it failed.

The gun was inexpensive at the time, was highly polished but buffed by someone not aware of how to minimize waviness in the flat surfaces. I bought it because it fit my hand like a glove. Too bad it was made of poor materials (??). But today we have real CZ’s and I have several along with the Kadet 22LR conversion.

Answer:

I’ve had a TZ-75 for over 20 years (the original one with the slide mounted hammer drop safety) and fired about a bazillion rounds through it, both in its original 9mm, and with the .40 S&W top end. I fit a Bar-Sto match barrel to both and it took some extra work because they were designed for the CZ and the original TZ is a little different in the barrel dimensions. The cross pin that holds the sear assembly in the frame eventually broke at the groove that locates the sear spring. EAA still has some parts for this gun which they imported as the Witness B. The only other problem that I had with it is the round extension on the barrel that serves as the hood was softer than it should have been and eventually battered into a mushroom shape that created loose breech. Again, EAA has barrels of all descriptions, and they are inexpensive. Other than that, fit a Bar-Sto.
