It's really not that hard at all for many of us. Getting FAC wasn't a big deal at all. I joined a club, completed my probationary membership in 6 months, applied for my certificate immediately thereafter, it was issued in a little over 2 months with all the slots I asked for and I had 6 firearms within 12 months of the first time I picked up a gun (with a few more empty slots for more guns when my wallet has cooled down). Sure, some people do have problems and it can take longer, but for many people with a clean record and no serious medical issues, you can get FAC very easily. In comparison, my American cousin who began shooting around the same time as me acquired less guns in that 12 month period and was still waiting for his suppressor tax stamp in the time I'd bought four of them. The UK is terrible for ignorant politicians pushing knee jerk, in effective and outrageously expensive bans, but when you set that aside, firearms ownership here is not nearly as bad as some make out and I'm also perfectly happy living in a country where they're not used for self-defence.
My UK FAC experience was basically the same as yours. About 9 months from joining the club to having an FAC. Then about 2-3weeks for each variation or a new gun slot.
Compared to the US, that really is 'hard' though.
I can go out today after work and buy whatever I want (except moderators and full auto stuff, which might take a year). It'll be in my hands in 5 minutes, maybe 30 if the background check software is slow. No home visit, no interviews, no fees, no references, no requirement for secure storage, no drama. No requirement for me to have so much as touched a gun before.
That is enough of a difference that the UK system does represent a barrier to the 'casual' buyer. You're going to need good reason, you're going to need to spend money, you're going to need to spend time and you're going to need to prove that you have good reason to own a gun.
Ultimately it's enough hassle that you're really gonna want that gun to be willing to deal with the process and by the time you have it, you'll have used firearms before.
That 6 months probation is quite a lot of firearms safety training, as is a couple years following a buddy around his permission, or a coupled of guided outings with an estate rifle, whilst even DSC1, a decent analogue for the 'absolute bare minimum experience for a deer calibre grant' in many instances, has some firearms handling and safety coaching. Without having some experience, you'll struggle to justify an FAC and so (at least some) experience is a requirement for firearm ownership. Not so here.
Personally I'll take the rare incompetent at the range over the UK system in a heartbeat, but it is a factor.
