Suppressors on smokeless MLers

Now that I’ve found that my ultralight 40 is truly a highly adequate 300 yard rifle, I’m considering biting the economic bullet and getting a suppressor for it. I’m aware that suppressors work far more efficiently with subsonic loads. I plan to keep my 2730’/sec 253 PH load. 

Currently, the recoil isn’t bad with the MB. However, my primary hunting area is quite noise sensitive. So, I have four   questions.

1) Recoil difference between my radial MB and a suppressor?

2) Noise reduction? 

3) Recommendations for what suppressor?

4) Other factors that I should be aware of?

Thanks.
