Having seen a break-in on one of these locks years ago i would recommend the use of a latch-guard also
BTW these type locks need to be fairly tight on the door, otherwise they will float around in the 2 1/8" mounting hole, and that will cause premature latch failure
I inherited a big box of these from my Dad when he retired (finally) and I don't Ever sell them. Once I had a client with a 2" backset, that is what they excel at, they make one weird size...
I guess the easiest way to explain why I feel that way: Would you regard your five-pin Medeco as more secure than a six-pin Medeco?
Yes, I know the usual objection to that argument is that the lock is not the weakest link. Granted, a burglar would probably just break a window. But while there's an argument that the lock is overkill, that doesn't make it a bad lock. The problem here is the deadbolt.
I could go to the locksmith and order all Medecos. I'd probably pay more. The locksmith probably wouldn't be too happy, seeing as they ordered an entire Primus (sidebar) bitting kit just so I could have these locks. And while you could argue that it's not my problem the locksmith sold me a combination that won't work, I also don't like being an a-hole customer. I'd prefer to work out a fix if I can.
At the end of the day, I specifically requested Primus cylinders after doing a fair amount of research on high-security locks and concluding that while there are more secure options out there (Abloy Protec in particular), the Primus seemed a good fit for me. The locksmith was trying to save me some money by ordering mortise cylinders and these US Lock deadbolts rather than simply ordering Primus deadbolts. While that turned out not to work well in retrospect, I'd rather change the deadbolts (if necessary) than the cylinders.
Your point about needing to mount the locks fairly tight to avoid premature latch failure is well taken. The current combination doesn't work well, and I will need to at least get different deadbolts if I can't find a good solution to make these work.
