A modular suppressor for all your pistol needs.

We are now in a 9mm world. The .40 is a part of history, and a lot of new shooters just don’t feel the need for the big old cartridge the .45ACP. (They are wrong on a lot of counts, but that’s a different subject, and article.) So, the big volume of suppressor sales for pistols is in 9mm. Well, what sales don’t go to a .22LR suppressor, that is. What if you could have it all? Tame the big but not noisy .45, and still be able to cover everything including the 9mm on down to the rimfires as well? To do that you need to look at the Banish .45.

Banish 45 Suppressor

The Banish .45 is a modular suppressor, in that it comes as two pieces. The two pieces are assembled as a single suppressor, and that brings it up to its full length and weight, of eight and a half inches and eleven ounces. At that length, it is very quiet indeed. Now, the length and weight would tell the clever suppressor user or buyer that there’s something going on there. Yes there is. The Banish 45 is made with a titanium tube (two tubes, actually) and it is filled with aluminum baffles. The tube is titanium to keep the weight down, and also to provide a rigid assembly without adding weight or bulk.

Yes, Silencer Central could have made it out of aluminum, which would have probably brought the price down (not that the Banish 45 is at all expensive) but the materials cost would have meant making the tube with a thicker wall. Instead of its inch and three-eighths outer diameter, it would probably have ended up at an inch and a half, maybe even more. And the .45, or the 9mm, doesn’t call for anything more robust in baffles than aluminum. Anyone who makes a pistol suppressor with Inconel or stainless steel, or titanium baffles is gilding the lily, and ramping up the cost.

The size of the Banish 45 is needed to manage the large volume of gas the .45 produces, and the benefit is that it makes the 9mm quieter as a result. With its light weight, you can, with the proper rear cap, put it on a rimfire rifle or pistol. If the length is too much fully assembled, then unscrew the forward part, remove the front cap, and install the front cap on the rear portion. Viola, you now have a shorter suppressor, and given the immense volume (compared to regular rimfire suppressors) it will be quiet.

To maximize the utility of your Banish 45 you’ll need an array of rear caps. For use on a .45 pistol you’ll need the booster, the Nielsen device, to keep the extra weight and leverage of the Banish 45 from stalling your pistol. Your .45 barrel will need a muzzle threaded at .578x28. To use it on a 9mm pistol, you’ll want to disassemble the Banish 45 piston, and then use a 1/2x28 piston. To use it on a 9mm PCC, or a rimfire, you then will need to remove the piston assembly and replace it with a solid direct-thread rear cap.

Do-It-All With One Stamp

It may seem like a tired adage, but it is true that to save money you have to spend money. You could buy three suppressors, one .45, one 9mm and one rimfire, to cover all your pistol-caliber shooting needs. (You’d still need two rear cap assemblies for the 9mm suppressor, by the way, for the PCC.) That could easily entail spending $2,500 or more on suppressors and mounts, not to forget the $600 in transfer taxes as well. At $949 for the Banish 45, and its included .45 booster mount, you only need the direct-thread mount which works for both 9mm and rimfire, as well as the 9mm piston. Those extras cost about as much as one transfer tax on one of those other suppressors. With the Banish 45, you can be into a multi-caliber (pistol and rimfire) suppressor for all your firearms for $1,200 or less. The $1,300+ difference buys a lot of ammo and range time.

Before we take the Banish 45 apart, why do this? Why make it in two pieces? Why not buy the short one, and then when you feel the need buy the extra and add it on? As it was explained to me, the regs allow you to make a suppressor less effective, but not more effective. Something along the lines of: making it less quiet is just making it less quiet, but making it more-quiet is making a new suppressor. (It need not be logical or rational, it simply has to follow the regs.)

So, in the short form the Banish 45 uses eight of the twelve baffles, and the full-length one uses all twelve. To disassemble, simply unscrew the cap, front or rear. (Or even both.) The aluminum baffles are keyed and indexed, so once you have gotten them clean (hand scrubbing, ultrasonics, Otis cleaning kit, or whatever works) you can index them by snapping them back into a stack before installing them into the titanium tube. Oh, and you can’t assemble the Banish 45 with just the shorter, front, section. That part can only be on or off of the longer half, not onto the base unit with the booster or rear cap.

Range Results

In testing, I used a new arrival here, the SDS Arms Raider that has been updated with an extended and threaded barrel and machined for a red-dot optic. The original has the model name Raider, but the upgrade has the prosaic designation of B45RDG TH. Really, it should be the Raider Plus or something like that.

I fed it a diet of 230-grain hardball to run through the Banish 45, and the pair perked along just fine. It hit to the sights with or without the Banish 45, and it was so much fun to shoot that my test-fire crew and I used up all the .45 I had along just in plinking and giggling. Not having a rear cap on hand to test it on a 9mm pistol or PCC, or rimfire, I didn’t, but I have no worries that it wouldn’t have let me down on those firearms.

As someone who is at the borders of off-the-rack clothing and shoe sizes, I find the phrase “one size fits all” to be laughable. Usually it means “one size fits no-one in particular.” No, the Banish 45 is not a one-size-fits-all suppressor, because you should not use it on a centerfire rifle. Well, a 5.7x28 firearm is within its limits, but anything just a bit larger I’d be leery of, and past, say, the .22 Hornet, I’d call it a hard no. If you want a truly one size fits all suppressor, you’re going to have to go a lot heavier or a lot more expensive, and what’s the point. No, Silencer Central knows what works, and they hit the sweet spot on this one. The Banish 45 will handle all the pistol and rimfire shooting needs you have and do it in style and with versatility. What are you waiting for?
