I don't think firearms training is much to do with flying. If you wanted to go there on Ryanair (assume they go there) you'd need to do the training too.
In fact, if you did go with Ryanair, you would definitely need survival and firearms training because you would have been dropped off 50 miles from the advertised destination
I don't wish to have a go at a UK flying magazine (a popular pastime here and elsewhere) but the typical readership is at a level where a serious "don't try this at home" disclaimer would be mandatory. The vast majority of UK PPLs, graduates of the esteemed JAA flight training industry at £8000 a pop, are completely unable to plan a flight from Goodwood to Malaga in perfect weather, and need a "cross channel checkout" to go to LeTouquet. A bit sad really, I think.
The 6 months referred to is clearly elapsed time, taking into account "life". A pro who does ferrying for example would have the logistics sorted in a week or two.
