22XX tubes have the breech screw location drilled in both the front & rear locations.  13XX have just the front screw location drilled in the tube.  Crosman makes both the front & rear screw loc. breeches.
In your pic it appears that the breech screw is not screwed in as far as it usually is, that is it seems to be sticking up a little.
May be the breech or maybe the screw could be tightened down some.

Wax works very well, not sure if it's going to stay there long... Maybe beeswax is better? will report

I may try the wax trick.

The 22XX tubes tend to have both screw locations where the 13XX tubes only have the front screw location

Thank you, I see. So, if I would buy the upgrade kit instead of going CCS route I would get a front screw hole? Or both?

Yes, the steel breech kit has the front location for the 4-48 machine screw.

I must say I dislike the new trigger spring. It's very light but it "unmasks" the creep and the trigger is overall very unpredictable. At least with the heavier spring you need to overcome its tension, but the sear releases once you do without dragging along the hammer. A .22lr casing as a spring guide and 1 coil clipped (2 coils and it doesn't reliably cock) is good enough for me, nothing will make it a target trigger really, nor should it be one. It seems good enough for "Minute of Squirrel" accuracy to me
