After further examination and review, he/they did decide the "little grub screw" on the left side (the same one mentioned in other posts as a possible cause of my problem) had backed out/screwed in a couple of turns too many. Evidently this can cause the action to lock up if the rifle is held at certain angles while working the lever. After adjusting this screw and blue loctiting it into place, they fired thirty-two rounds (each?) of .38 special and .357 magnum without any problems whatsoever. The action has been thoroughly examined and adjusted, and seems to be working perfectly.
He apologized for the frustration of having a brand-new firearm malfunction like this one did, and for the delay in identifying the cause of my problem. He then promised to return my carbine to me forthwith.
I am relieved that SOMETHING was found to be out of adjustment, leading to my lockup problem, because that can be fixed easily. I am also glad they agreed that I had a real issue, not an imaginary one.......

Finally, I am glad to know that my new R92 will be back in my hands very soon, and I can get back to sighting it in! I'll check in here and let you-all know when my rifle arrives; and how it shoots, when I can get to the range to try it out.
