The new Endure sound suppressor from SIG SAUER is 3D-printed out of titanium alloy. This makes the can diaphanously lightweight and effective on a whole new scale. A .30-caliber snuffer that will run most anything that will comfortably fit through it, the Endure is custom-designed to revolutionize your hunting experience.
Why Now?
Thanks to runaway inflation and, most recently, the removal of the transfer tax on sound suppressors due to the Big Beautiful Bill, firearm silencers have become easier than ever to acquire and own. As we live in the most refined consumer economy in human history, the industry has geared up to meet that fresh new demand. As a result, nowadays the country seems to be covered in a thin patina of sound suppressors. Cans for everything from rimfire plinking guns to combat pistols to modern sporting rifles are more readily available than ever before.
While suppressor companies are churning out silencers like there is no tomorrow, there has arisen a fresh new market that orbits around sound suppressors for hunting applications. Hunting cans need to be compact, lightweight, and effective. They should also be weather-proof and not exorbitantly expensive. SIG SAUER recently launched the optimized sound suppressor for sporting weapons. The SIG Endure supressor will change the way you hunt.
The Landscape
In years past, we tormented our ears mercilessly. I emerged from the delivery suite with an inexplicable passion for shooting and the outdoors. However, I did not invest in a decent set of hearing protectors until I was nearly twenty. Back then we just didn’t know any better. Now that I am sixty years old, I have already begun paying for that.
Nowadays, technology can help us out. Forty-two of the fifty states allow private ownership of sound suppressors. Of those forty-two, forty-one will let you use a suppressor while hunting. Connecticut is the inexplicable outlier. I have no idea what that’s all about.

If you’ve not yet had the pleasure, threading a sound suppressor onto the snout of your favorite hunting rifle will absolutely transform your time in the field. Everything about that addition is good. The extra mass dampens barrel harmonics and enhances accuracy. The diminution of racket makes you a more neighborly shooter, helps preserve your hearing, and renders you a stealthier hunter. In the past, acquiring such an nifty trinket was both expensive and an administrative pain. Now it is just a pain.
Background
The 1934 National Firearms Act was the first regulation on sound suppressors for firearms. This rancid pile of extra-Constitutional tripe levied a draconian $200 transfer tax on gun silencers. As $200 in 1934 was the equivalent of more than $4,000 today, this edict quite effectively crushed the legal market for such stuff. And thus things remained for some 92 years.
The Big Beautiful Bill, which took effect January first of this year, adjusted the transfer tax on suppressors and short-barreled guns from two hubdred dollars to zero. The registration and regulation scheme tragically remained, but the costs got way lower. This opened the floodgates on suppressor ownership.
No kidding, pre-2026 there were about five million suppressors in the registry. That number increased by 800,000 in the first three weeks after the law changed. The transfer process is a bit onerous, but anyone of reasonable intellect can manage it. The details are readily available online. If you can navigate your cell phone contract, you are lyrically overqualified to transfer a sound suppressor. The new Endure from SIG is the perfect general-purpose hunting can.

Details
The Endure suppressor is 3D-printed out of Titanium for minimal weight and a crazy long service life. More on that later. The can is only six inches long and weighs a paltry 11 ounces. The tube is 1.75 inches in diameter. The Endure comes from the factory with a direct thread 5/8×24 steel mount.
This suppressor is optimized for use on bolt-action hunting platforms. The exterior features a cool topographic pattern that looks vaguely like a map. When coupled with its high-temp Cerakote finish, this minimizes glare and keeps you stealthy in the field. The whole shebang is covered by SIG’s amazing limitless transferable warranty.
Entrails
The key to the Endure suppressor’s light weight and exceptional effectiveness is its rarefied engineering and cutting edge materials science. 3D printing is also known as additive manufacturing, and it is revolutionizing the way human beings make stuff. We now see 3D printing in everything from toys to complex aircraft parts to building manufacture.
3D printing had its genesis back in the 1980’s as a cost-effective method for prototyping parts that could subsequently be mass produced via more traditional methods. The entire enterprise is driven by the capacity of computers to precisely maneuver a control head in space. Basic polymer 3D printers are vaguely akin to hot glue guns. The most common is called fused deposition modeling. In this case, computer-driven actuators feed a continuous filament of thermoplastic material that is heated until it flows then allowed to cool into the desired shape.
Elastic Vs Plastic
In engineering parlance, the term elastic means deformation that snaps back to an approximation of its original shape. By contrast, plastic is an adjective that simply means a change in shape that is permanent. Rubber bands and Stretch Armstrong are elastic. Paper clips bent double are plastic. Thermoplastic therefore intimates a process wherein warm liquid material hardens into a robust solid geometry once it cools.

Over time, this process has found some of the most fascinating applications. 3D printers can actually deposit liquid concrete to create buildings. As it relates to our discussion today, however, this same technique can create complex and robust metallic parts.
In the case of 3D-printed Titanium, a high-energy laser sweeps across a layer of powdered Titanium substrate, causing the Titanium to briefly liquify and then cool into complicated shapes. By making multiple passes and building this material up layer-by-layer, metal 3D printers can craft some of the most extraordinary shapes while retaining the strength and durability of the native material. SIG engineers use this process to optimize the entrails of the Endure suppressor for maximum effectiveness and minimum waste.
Titanium is a durable, lightweight material with scads of exotic engineering applications. However, it is also fairly expensive. 3D printing minimizes wastage and helps keep production costs down. The end result remains affordable for the common man.
Practical Tactical
The Endure supressor really is stupid-proof. All you do is thread it in place on the muzzle of your favorite bolt-action rifle and hit the range. The design demands no maintenance beyond a quick wipe-down before stashing it back in the gun box. Most .30-caliber firearms utilize standard 5/4×24 threads. There are adaptors available that will allow you to use the Endure can on 5.56mm platforms as well.

The Endure supressor is not designed to digest mag dumps from machineguns or manage belt-fed madness. SIG makes other sound suppressors for those applications. However, use the can as intended on a bolt-action platform, and you will legitimately never wear it out.
All else being equal, sound-suppressed precision rifles generally shoot better with cans installed than they do without. I exercised the Endure can on a SIG Cross rifle in the Army’s new 6.8x51mm cartridge and rang a 12-inch steel plate at 1,000 yards for as long as I cared to ring it. This suppressor will run fine for any reasonable hunting application.
The Endure excises the painful bit from the sound of the gunshot. The supersonic bullet still makes a sonic crack, but the rifle thusly equipped is way easier on the ears. It is also all but impossible for a target to localize the source of a suppressed rifle shot.
I ran the Endure can on my favorite .308 Remington 700 as well. Roll your own subsonic loads, and the Endure is legit movie quiet. It is amazing the performance you can squeeze out of such a compact sound suppressor.
Suppressors Are The Future
Our weird little world is changing. You can feel it. Sound suppressors are clearly the wave of the future in the shooting sports. The time is coming, sooner rather than later, when most everybody will be using them. There’s simply no reason not to, unless you live in a state where they aren’t legal, of course. Amidst this bold new milieu, SIG introduces the Endure, a can specifically designed to make your hunting rifle both more efficient and more effective.

Most hunters latch onto a gun they like and develop an almost unnatural affection for it. The Endure supressor makes that great gun even greater.
