One thing that's gonna happen is you'll find availability of threaded barrels for pistols or rifles with thick enough tubes to thread factoring heavily in your decisions on new firearm purchases. Once I started shooting suppressed, I began threading a decent portion of my collection, including stuff I didn't think I ever would, like my 700 BDL .25-06.
You're also gonna find yourself annoyed at having others at the range who shoot unsuppressed!
Agree on all that, I can testify!
When I bought my R55 Benchmark, suppressors weren't even on my radar. That rifle has a heavy target barrel and as far as I am aware there were no versions of it sold with a threaded muzzle.
A chap at my club let me shoot his CZ452 which had a basic suppressor, I think it was a cheap Parker Hale. From that point, the penny dropped.
Here was an accurate .22 that I could fire without ear defenders, as long as I used the right ammunition. In those days you could not get hollow-point ammunition for range use because expanding ammunition was restricted. All the readily-available ammunition in .22LR was solid but you could still shoot suppressed if you got Eley or RWS at around 1066 fps. It was hearing safe, without the supersonic crack.
I immediately sent my R55 to a gunsmith and got the barrel threaded for a suppressor. Same with my second R55: it was bought second hand but I got it threaded just the same. This is my R55 with a UK Custom Shop Predator 12 reflex suppressor attached:
Like MachIV says, a threaded barrel is now a must-have for any .22 rifle I buy. There will be exceptions for classic guns with irons that can't be easily threaded but in the main I demand threaded!
It was for that reason I originally bought a SIG522 and after that my 10/22 clone, the Rimfire Magic rifle also in .22LR.
I got into suppressors in a serious way because I test them. We are fortunate in the UK to have somewhat easier access to suppressors than in the US. Sure, they are licensed items in the UK but there isn't any resistance to getting them put on license. It's all about health and safety, of course. Hearing protection!
Spats would do well to take stock of his finances, because they will surely take a hit. I've spent over £1000 on my collection which is currently 15 rimfire cans and one 12g can also.
Variety, gents...it's the spice of life! Some of my other cans:
