Is this grammatically correct? (go get...)?

Question

I'm just confused and annoyed with today's grammar. As far as I know, it's alright to use "go" if it's preceded by a gerund. For example, "Let's go swimming." or "She wants to go shopping."

But how about with a noun? For example, "Go get one!" or "Go get them now!"

Is this acceptable?

I'm too particular with grammar. But I don't know some new trends about English today... ~~

Thanks for the no-nonsense answer.

Answer 1

Yeah using it if it's preceded witrh a noun is accpetaple

Answer 2

you might be more comfortable with "go and get x from the store" or  "go and get one"
