As mentioned in a previous thread a couple weeks ago I flew a L935 which uses a Pro54 6-GXL casing. All Pro54 6-GXL reloads are listed as plugged on CTI's website. That said, the CTI Pro54 L935 motor I flew, whilst being labelled as a plugged motor, actually WASN'T plugged, much less threaded. Historically CTI Pro54 plugged forward closures had a threaded insert for positive motor retention and were plugged (as in, the forward closure was fully sealed from the combustion chamber).
The forward closure that came with my L935 had a circular cardboard insert with the letter "P" written on it over what should have been the threaded insert. I carefully removed the cardboard insert and was quite shocked to see an empty charge well and the top of the smoke grain. I was able to work around this and effectively threaded the forward closure to my motor retention point but I thought this might be something worth mentioning to the community. For the record it also appears that CTI have added a second O Ring to the forward closure of some of their 54mm motors. Maybe this is due to the K300 CATO issues? Regardless, ideally I would prefer to know about these changes before I'm on the flight line. Is this sort of thing documented anywhere?
