Good afternoon subsonic adventurers and welcome to the 145th edition of TFB’s Silencer Saturday brought to you by Yankee Hill Machine, manufacturers of the new R9 suppressor. Last week I laid out ideas on some of the best 9mm pistol hosts currently available. This week we head back into the ‘best millimeter’ world with a special treat – a 9mm bolt action rifle and an integral suppressor – both from my friends at Curtis Tactical. Some of you are scratching your heads saying “why would I want a bolt action 9mm host?” The rest of you are rubbing your hands together with a Gollum-like look in your eyes. Let’s take a look and see why this could be a significant milestone for quiet shooters.

SILENCER SATURDAY #145: 9mm Bolt Action Integral – Curtis Tactical
The Holy Grail in the quiet shooting world is a super quiet platform that is fun, useful and cheap to shoot. Unfortunately, in the days of election-pandemic-socialunrest-armageddon-2020, nothing is really cheap to shoot, but one day 9mm will be inexpensive and available again. As rifle hosts go, bolt actions are at the top of the list for their obvious lack of blowback when suppressed. On the other hand, chambering selections for subsonic calibers are limited:
- .22LR – rimfire ammunition energy limitations
- 300BLK – expensive ammunition
- .357/.44/Straight-Wall cartridges – limited host availability
Let’s talk about the iconic 9mm pistol cartridge – affordable and available with heavy modern bullets, it is a capable personal defense round that makes for quiet shooting (I’ll take all the .45ACP/10mm arguments you want to dish out in the comments section below). And it’s not like 9mm doesn’t know it’s way around a rifle – it has a long and successful history with submachine guns and pistol caliber carbines. But as good as the roller delayed action H&K MP5 is to suppress, a decent amount of gas and noise makes its way back out the ejection port. What suppressor aficionados want is a bolt action 9mm rifle with a silencer that has a large amount of internal volume.
We’ve covered one 9mm bolt action rifle in the past: the Special Interest Arms Novem built on the Armscor .22TCM carbine action. This carbine’s main limitations are the original proprietary magazines that hold five rounds and stock/chassis choices.
Enter the Curtis Tactical CT700P, the first in a what will eventually be a lineup of bolt action pistol caliber carbines that will also come in 45ACP (1911 magazines) and threaded barrel versions. The model I’m borrowing is obviously chambered in 9mm, is integrally suppressed and takes GLOCK mags.
The CT700P is built on a Remington 700 action and features a removable magazine block for GLOCK mags. Unfortunately I don’t have all the pricing, specifications and availability details yet, but I’ll get a full review out shortly with additional details from Curtis Tactical.
The integral version uses clipped cone baffles that are sandwiched between an internal end cap. A large hex wrench is used to unscrew the caps and the baffles slide out easily because they are shielded from the tube.
The bolt and extractor are machined specifically for the 9mm cartridge.
The magazine release on the KRG chassis drops the magazine block easily. I did have some issues seating a loaded magazine on a closed bolt, but I’m guessing this will be addressed in the models available commercial sales.
The permanently attached suppressor tube makes this a one stamp gun, so I can’t measure the actual barrel length. If I had to guess, I’d say the barrel is nine inches long. Don’t worry, I’ll get all the specifications for you shortly.
I’d guess you call Curtis Tactical a boutique manufacturer, but they make fantastic suppressors, especially their integral models. I’ve talked with Joe on and off for almost five years and know his customers are very satisfied with his work.
Fully loaded and outfitted with Trijicon’s MRO and the KRG chassis, the whole setup weighs between 6.5 and 7 pounds. For the most part it feels and handles like any other Remington 700.
Accuracy was surprisingly good at 50 yards with a solid two inch group. For today I was using the Seismic Ammo 185gr subsonic rounds. Cycling the action was fairly smooth with only one double feed that I attributed to my general lack of coordination.
As for the noise, this has to be one of the quietest centerfire platforms I’ve ever shot. It was completely deceiving because it sounded like a well suppressed rimfire rifle, but had the recoil of a 300BLK bolt gun. This is an amazingly quiet 9mm carbine – I don’t really have anything to provide you with an accurate comparison.
I’m sure the CT700P will get some minor refinements before it is available for purchase, but as a suppressed 9mm platform, this is as quiet as it gets. Truly a dream to shoot. I’ll put some more time behind the trigger and report back.
Have a great week. Be safe, have fun and we’ll see you here next weekend for another Silencer Saturday.
