22LR Form 1 Suppressor w/ AAC-style K-Baffles

After a 13 month wait for approval from the almighty FedGov and about 40 hours of machine time, I've finally finished my first made-from-scratch suppressor. Final specs: 5.4" long and exactly 9.0 oz.

316SS seamless tubing and 416SS internals, all turned on a 1955 Southbend 9A lathe and who-knows-how-old Russnok vertical milling head on a horizontal mill base. No DRO or CNC, thank you very much - all old school hand-crank and dial reading!

Finished product, blasted and Gun Koted:


Finished baffles (6 of the 9) and end caps:


First operation: cutting the cones from 4416SS bar stock


Second operation: turning the bottom trough


Turning operations complete;


Plunge cutting bottom mouse hole with a 1/4" ball end mill:


Cutting the top mouse hole with a 1/4" ball end mill:


Making the kidney-shaped cuts with an 1/8" ball end mill:


Using a rotary table to take the kidney-shaped cuts through a 45° arc:


Cutting the alignment slots:


Cutting the alignment tabs:


Cutting the wrench flats on the end caps:

You did great work on that. I have no doubt that it's going to give you a lifetime of use and pleasure.

If I may ask though, what cutter tool were you using to machine in the trough?

That's just a custom ground HSS blank I made into a bullnose shape.

Great job on everything.

It looks better than AAC baffles in all fairness and honesty.

You ever want to get rid of your home made cutter, I got dibs

Man was that a lot of manual machining. Was that a homemade steady on the southbend?

Not homemade, but I'm not sure where it came from. It's been around awhile!

Today when out playing with the pistols:

Wife: That looks ridiculous! You look like Starbuck -
Me: I think you mean "awesome."
Wife: No, I mean ridiculous.

Then I realized that Starbuck was awesome, and every woman in the Galaxy totally wanted him.



But on a more serious note, I was curious to see about any POI change or accuracy change. There seems to be a slight shift down and left with the suppressor mounted, and either it increases accuracy or it allows me to shoot better more easily - either way I'm happy! Shot freehand at 10yds:

Discovered my 9mm SIG 2022 Tacops TB with Osprey can attached fits almost perfectly in Bianchi shoulder rig for 8 3/8" Colt Trooper. Stuns gun guys when slip it out to show it off and realize have 17 rounds of Federal 147 grain HST and suppressed SIG under weak side arm and second SIG 2022 Tacops TB in strong side holster. And rack of spare magazines. When tell them about only way feel comfortable with a minor caliber/women's gun for primary get some odd looks as most people seem to think 9mm is a real offensive handgun caliber.

Finding a workable holster for suppressed pistols can be challenging. And some people think adding a laser makes finding a holster difficult. If want to carry a suppressor with my SIG 1911 Tacops TB have to carry can separate on belt next to spare magazines and of had time could remove and thread on gun. Otherwise it's hope had the foresight to put my Sonic II's in soon as realized in high threat situation and before drawing weapon quickly was necessary. When work church security usually have Sonic II in left ear and without in right ear as weak side ear gets more muzzle blast and people assume it's a Bluetooth device.

Someday going to buy or build a short suppressor that only reduces the sound pressure enough ears are not bleeding after an encounter. Believe could put an Officer's Model length slide on standard 1911 frame and build/contract custom can so ends up about same overall length as a 6" long slide and with a 200 grain 45 acp being subsonic would not be oppressive if used without ear protection.
