A few months ago I traded for a 98+% baby Desert Eagle (Magnum Research branded Jericho 941) with the polygon rifled barrel made during the IMI era. I previously had both the CZ 75B and the CZ 97B and found both to be well made, accurate, and reliable. That said, I do like the Israeli gun a bit better, mostly because I can easily remove the firing pin for cleaning out its channel as in the pre-B CZs. As for CZ magazines, I kept several spares and to make them work exactly right in my baby Eagle I had to remove a bit of metal at the top of the magazine catch slots and install narrow-frame Witness followers so that the slide holds open after the last round is expended. Once those mods were made, the magazines fit well, feed well, and function properly in every way. I judge the machining and fit to be slightly better on the Eagle. I also like the polygon rifling. I can tell you that both the barrel and the slide are very, very hard. I have not checked so cannot say about the receiver. I own, carry, shoot (at least when ammo was more available and so much more cheaper), and table-top smith many, many pistols and revolvers of various makes and calibers. If I could have only one handgun, it would be a Glock 19. Nevertheless, I really like the Eagle/Jericho 941 and would feel confident carrying it for defense.
