My father went to the doctor with a sore throat. Turns out that he had advanced lymphoma, his whole body was shot through with cancer. He lived about 3 months.
If you can genuinely afford it, go get the suppressor. Because there are no guarantees in this life, of anything.
If you have been wanting something for 10 years, it's not a passing fancy.
The nice thing about buying gun stuff is that it's a one-time buy. Decades ago, I bought a S&W 617 for about $700 in today's money. It still looks brand new. I have spent zero dollars on it since then, aside from a drop of lube here and there. I could sell it on gunbroker for about what I paid.
People don't end up poor from buying a $700 suppressor. They lose all their money from buying stuff like new cars and expensive vacations.
That suppressor is basically one single car payment on a $35,000 car.
One thing to keep in mind is that the suppressor will change the noise from HUGE to "sort of loud-ish." It's a nice improvement but don't expect action movie quiet. I don't use my suppressor that much because I like the balance and handling of the gun without it.
Also, I had to get a threaded FBI length barrel for my suppressor, the accuracy was horrible with a barrel nut mount. Some UZIs do not work well with the barrel nut mount, for reasons unknown.
