A later compact version, the Jericho 941, was chambered in .45 ACP or 9 mm. It is not clear to what extent the Jericho original .41 AE/9 mm Jericho frame and slide were "built-up" to handle the .45 ACP's much larger diameter; although the .45 ACP is a milder load running at much lower pressures than the .41 AE, the barrel opening for the .45 ACP is, of necessity, much larger. Desert Eagle does not permit the use of +P or +P+ loads per its website FAQ, although reviewers have shot and reported the ballistics on +P .45 ACP defensive loadings.
