not sure, haven't tried the mags for em. its a really good shot, can get some pretty tight grouping on it. buddy has the same gun in the .45 and he put 5 shots at 3 yards in the same hole about the size of a half dollar. of course he is precision firearms instructor. ill have to upload some range shot pics when i take it out again.
Just mentioned it because I know that some BUL and EAA models are cross compatible with cz mags. There are also extended hi-caps for the cz too. You should look into it if they are compatible with your eagle.
