Pistol Suppressor Host

Keep an eye on Volquartsen's clearance page:
They'll have various MKIV factory uppers for cheap. Think they had some Lite uppers last month.

I run a bull barrel mkII that I had cut and threaded. It has Volquartson trigger, better target sights, etc. Can is a Dead air mask, nearly everything cycles the action and it is movie quiet with subs. I shoot all kinds of stuff through it. I don't have a favorite.

I have a couple of M&P22 compact pistols that run flawlessly with CCI SV and my Sparrow. Those guns bring big smiles to the shooters’s face every time they come out of the safe.

When I got my first can, I had it down to threaded versions of the ruger MK IV, browning buckmark and the new ( at the time ) S&W victory. I lean toward traditional style single action triggers and guns. I ended up finding a victory new and cheap ( $300 or so ) and it has been near 100% reliable with everything ( did have one type of ammo that choked it- but the same ammo gave me issues with other guns too) and near bullseye competition accurate. Great adjustable sights and a scope rail included if that is your thing. I have been very happy with it ( which is saying a lot for a guy who hates stainless guns)
I really wanted a ruger ( the factory is just 15 minutes from my house and sort of wanted to support local business and jobs) but the lease expensive ( again at the time) ruger available threaded was almost 200 bucks more than the victory, I have heard and seen lots of people saying they had to do a fair amount of tinkering to get the MKIV to run

I run a Volquartsen Scorpion and it is an amazing host. The DLC bolt keeps running even after several hundred suppressed rounds, it has a machined top rail for optics, it is accurate and has a mouse-click trigger. Huge fan. I solely run CCI SV suppressed and unsuppressed without any issues. Just buy bricks and enjoy.

In saying that, since you already have a MK IV pistol, I would consider a DLC bolt & Mamba upper from Volquartsen to swap onto your frame. You can always to the VQ trigger and have a great little host plinker.

These Ruger designs just run and Volquartsen's enhancements just make the whole package more fun.
