Good afternoon subsonic shooters and welcome back to another edition of TFB’s Silencer Saturday brought to you by Yankee Hill Machine, manufacturers of the YHM R9 suppressor. Last week we looked into the classic three lug mounting system and the YHM R9 as a capable and affordable pistol caliber carbine suppressor. This week we return with more information on the Curtis Tactical 9mm CT700P integrally suppressed bolt action rifle and a comparison to one of my all time favorites, the Ruger 77/357 suppressed SBR. There’s no use holding out on you, the Curtis Tactical CT700P is one of the quietest centerfire rifle setups available today.

And as you’ll see below, it’s also available in 10mm, .357SIG, .45ACP and .40S&W.

• SILENCER SATURDAY #145: 9mm Bolt Action Integral – Curtis Tactical

Curtis Tactical 9mm CT700P

https://curtistacticalsuppressorsandrifles.com/curtis-tactical-brand-rifles/CTSR-CT700P%20-on-remington-700-sa

The CT700P is currently available in 3 models, KRG, MPA, and Pork Sword. We are currently designing our own chassis that will be close to the Pork Sword design and have interchangeable magwells so no adapters will be needed.

The KRG and MPA are sold as rifles and the Pork Sword is sold as a pistol. All three models have the same basic features with the chassis being the difference. The receiver is machined from 6AL-4V titanium and is DLC coated. The receiver accepts R700sa scope bases, triggers, firing pins, and stock/chassis.

The bolts are machined from 17-4ss bar stock, the bolt has a threaded handle and is UltraOX nitrided. The design on the bolt face is where the design is critical to get the pistol rounds to feed in a front lug action. Our patent pending angled t-slot machined into the face of the bolt makes this a true controlled round feed and is necessary to feed the pistol cases. As the round exits the magazine the t-slot on the front of the bolt captures the case rim, it is machined to the perfect profile to allow a smooth feed up the feed ramp into the chamber while being retained the whole time.

The side mounted bolt stop also plays a big roll in the ejection, as the bolt is moved rearward the bolt stop actuates the ejector which is spring loaded to the rear. The magazine adapters are also an integral part of the system.

Three adapters are available:

• 9mm, .357SIG, .40S&W adapters use small frame glock magazines
• .45ACP, 460Rowland, and 10mm can use 1911 or G36 mags.
  
• All the adapters fit AICS pattern mag wells to adapt the pistol magazines.

All stainless parts are finished with UltraOx nitride, all aluminum is type III hard black anodized.  All models come with a 20moa scope base, Trigger Tech Primary trigger, mag adapter, and one magazine. The barrels on all models come in a medium profile with a threaded muzzle.

• KRG Bravo chassis – $1475 MSRP 
• MPA Ultralite chassis – $1999 MSRP
• Pork Sword chassis with side folder brace and 8” forend – $1744 MSRP 
• CTSR Chassis with a side folder brace or fixed rifle stock – $1744 MSRP 

Standard options with no additional cost include:

• Rifles 16” or 20” barrel
• Pistols 3”-12” barrel
• 45acp and 10mm choice of 1911 or G36 magazines

Options with additional costs include:

• Integrally suppressed barrel rifle or pistol +$600 (barrel assy. Is Cerakoted)
• Match barrel (Douglas) +$125
• Ultra match barrel (Krieger) +$200
• Barrel fluting straight +$125, Helical +$200

Shooting the Curtis Tactical 9mm CT700P

I won’t bury the lead – the CT700P is the quietest centerfire rifle I’ve shot to date. However there are some close contenders. The Remington Model 7 in 300BLK with a quality round like one from Discreet Ballistics or SIG Sauer is also super quiet. And the Ruger 77/357 with a subsonic .38Spc wadcutter round is almost as good as it gets. But the large internal volume on the Curtis Tactical rifle pushes it over the edge. Let’s take a look at some attribute comparisons other than just pure sound reduction.

Magazines: Advantage CT700P

A 9mm bolt action rifle is made infinitely better with the ability to use widely available GLOCK magazines. Capacity is not a huge deal in a bolt action rifle, but the five round limitation for the 77/357 mags is a bit anemic. There are some aftermarket possibilities on the horizon for the Ruger.

Precision: Advantage CT700P

Given my mediocre skills and the ballistic limitations of the 9mm bullet, I was surprised at being able to shoot 1.25 and 1.5 MOA groups with the 185gr Seismic Ammo round at about 100 yards. The 300BLK round will allow for better bullets if you are looking for precision. However, the CT700P out performed the 77/357 by a good margin. Maybe there’s a better subsonic .38Spc round for shooting 100 yard groups?

Action: Advantage CT700P

Both the 77/357 and CT700P have an average feel when working the action, but the Curtis Tactical rifle feeds the 9mm rounds more smoothly and reliably. Granted, the wadcutters are a less than ideal comparison round, but even with a JHP .357 Magnum round, the CT700P fed, extracted and ejected more consistently than its Ruger counterpart.

Price: Advantage Ruger 77/357*

When comparing MSRP’s, the Ruger wins. However, there are a few caveats. The first is availability; the 77/357 was out of production for a few years and, even when it’s being manufactured, they can be hard to come by. The second caveat is customization: there are only a few stocks made for the Ruger, whereas the CT700P is built on an action with dozens of stock and chassis options. And don’t forget to factor in ammunition prices – in normal times feeding a 9mm with commercial subsonic ammo will be cheaper and easier than subsonic .38Spc or .357Mag ammo. Lastly, barrel threading and NFA SBR registration will add nearly $400 to the Ruger’s price tag .

Conclusions:

I love both of these guns – they are super quiet, accurate and fun. But a suppressed 9mm bolt action rifle that takes GLOCK magazines has always been a grail gun of mine. And Curtis Tactical has made it a reality. With the right ammo and optic, the CT700P is a rifle you’ll shoot at every range session and is capable enough to take medium sized game. If it wasn’t for the slight bit of recoil and a heavy bullet impact, you’d swear you were shooting a suppressed rimfire rifle.

Thanks for reading. Be safe, have fun and we’ll see you here next weekend for another Silencer Saturday.
