MSRP is $500 and I've seen them on the net for low $400, what can would you recommend?
Depends on what is most important to you really, but I would recommend a Silencerco Sparrow if it will get alot of time on both rifles and pistols, and a SWR Spectre if you will use it more so on pistols.
If you want an aluminum can for weight or cost issues, then the SWR Warlock cannot be beat for price, ease of cleaning, and suppression.
