Donny FL extension for .357

[bigbuck28]

I have an FX2 in 35 with the 700mm barrel plus Donny FL ronin on the end. Love it

A buddy has the same gun and added the Donny FL extension, it cut the report in half no lie. Seriously impressive 


But I did notice his barrel kinda has a vibration after the shot watching him shoot.(I can watch the barrel move up and down after the shot) 

Is this bad/ good ?
Would barrel supports help for this or is keeping it freefloated the best for accuracy. 

We were only shooting 30 yards.

All barrels have "harmonics"....just a matter of how much

Am I better off keeping my FX impact like it is and getting a 30 cal maverick compact and putting a Ronin on it

id like a super quiet gun for day time plinking in the back yard. Would a maverick compact with standard ronin be quieter then the .357 with ronin and extension bc it was legit mouse fart quiet

I would say Maverick compact in .30 cal will be little bit louder then your Impact...for plinking go with .22cal or .25cal much quieter and cheaper to shoot.
