Amira's challenge was outside of Samson's expertise. His specialty was LONG distance, precision shooting, not bar-room brawl distance shooting. He needed to consult with some experts. He wasn't going to deliver something that didn't address the issues Amira had pointed out.
The next morning Samson walked to the eastern edge of the Cumberland Plateau and found a position on the cusp of the Tennessee River Valley where he could visually see the eastern suburbs of Chatt. He was a quarter mile east of the official boundary of Copperhead Cove.
He moved around a bit until he had three bars of signal on his cellphone and then started typing...

Subject: Advice needed re weapons for indig personnel
Background: Twenty small-stature to very-small-stature potential combatants need weapons with following characteristics
- Accurate enough to hit paper-plate at 50 meters with minimum training
- Very low recoil and muzzleblast
- Detachable magazine
- Enough projectile mass to disrupt central nervous system from frontal center-of-mass hit at 50 meters
- Compact, lightweight (six pound max)
- Low cost platform and ammo. Many potential combatants, low funds.
Need recommendations.

Have you considered M1 Carbine. Designed to replace M1911 .45 ACP handgun for use by cooks, truckdrivers and REMFs.
Sounds exactly like what you are looking for.

Time passed and much internal discussion within thread. The various plusses and minuses of several semi-auto platforms were discussed. Then...

Looked at M1 Carbine. Magazines are junk. Need robust magazines.

Even more time passed

Please advise regarding projected cost.

Looking at a bulk buy for CHMSL barrels, roughly a C-note per copy.

End Session:
The prototype showed up in six days and was tinker-toyed from many AR parts because they are abundant and ergonomically excellent. For example, the fire-control groups were scrounged from the builder's parts drawer. Triggers are one of the items most frequently upgraded from "stock" ARs and "stock" was plenty good-enough for Amira's specification. Ditto for the buffer-spring that powered the bolt which the builder had fabricated from laminated steel, similar to the core of a low-voltage transformer.
Samson was delighted with the additional AR parts. He saw them as inventory-on-the-hoof. They were fair-game to cannibalize should the high-end weapons need those parts.
The 6" 9mm Luger barrel was pressed into a 16-1/2" long tube to make it legally a long-arm. The receiver was 3-D printed and it even had a serial number on it (CCArms, LGB-A001) to make it legal. The mag-well accepted Glock magazines and the forearm had a dovetail for a light and posts for a sling. The sights were on the barrel-tube, a tall ghost-ring rear and a simple, hooded post in the front.
Samson took the weapon out for first firing and he encountered some short-stroking. He determined that the bolt had some burs on it that were scraping the molded-in metal guides that trapped the bolt. He stoned the bolt to slightly chamfer the rough edges and reran the test with only two failures of the bolt to travel far enough back to pick up a new round.
Samson reread the notes the builder sent with the "build" and learned that there were spacers in the buffer-tube to increase the preload on the spring. He started playing around by removing spacers and deliberately "limp-wristing" the wimpy, generic, white-box 9mm ammo in an attempt to make it not-cycle. He stopped removing spacers when it ran ten-in-a-row even in limp-wrist mode.
Once he was happy with how the rifle was tuned in, he filed the front sight to raise the point of aim to a 75 meter zero and then invited Amira, Sarah and Sig to shoot it.
Bracing the weapon against a tree trunk, simulating shooting from a doorway, Amira was able to keep ten shots at fifty meters in a group no larger than a softball.
Sig suggested that the front post should be thicker for better low-light visibility. He also suggested that wooden butt-stocks could be fabricated in Copperhead Cove to reduce cost at a penalty in weight.
"How soon can we have all 20?" Amira asked.
Samson frowned. "There are always bugs that don't show up until the lead units get enough exposure to several different shooters and different types of ammo. I want to make five and get them out to shooters of different heights and get some rounds through them."
"After we bubble-up and solve the issues on those, I want to make another batch of five" Samson replied. He had anticipated the question. "Point being, if we have the parts in-hand, they are much easier to modify as loose-parts. If I build them into working rifles then we risk damaging the receivers if we have to do a full disassembly. The receiver is just plastic, after all."
"I want one of the first ones" Amira said.
"If it is alright with Sarah and Sig, you can have the one you are holding" Samson said.
That brought a BIG smile to Amira's face.
"The next question is, where are we going to get $2000 for the parts and another $1000 for ammo, extra magazines and other odds-and-ends?" Samson asked.
---Note to my readers---
Thank-you for all of your comments on the previous Cumberland Saga post!
This is a work of fiction and undoubtedly many of my more sophisticated readers are already thinking..."but it doesn't work that way...". My challenge as a writer is to produce vaguely technical sounding text that seems plausible and paints pictures in the reader's heads while not strangling the story with excessive detail.
I will be disappointed if some commenters don't take me to task, though.
9mm seemed like the only choice. It is the cheapest centerfire ammo and really does replicate .22LR ballistics with three times the mass out of a 6" barrel. Longer barrels only gain about 100fps compared to a 6" barrel according to Ballistics By The Inch.
Ballistics: 2" high at 50 meters with a 75 meter zero and 3" below the line-of-sight at 100 meters. With a muzzle velocity of 1100fps, velocities of 1020fps at 50 meters and 960fps at 100 meters. Getting plunked in the noggin or heart/lungs by 124 grains at 960fps will quickly end the party for you, even if the bullet is going too slowly to expand.
The final nail in the coffin of 9mm vs .22LR is that most centerfire arms are less likely to be damaged by dry-firing than most rimfire arms. When ammo is dear and noise is to be avoided, dry-firing is your friend. It makes flinches disappear.
To the Marines out there: Samson was not a Marine but is allowed to be on the ring by virtue of being able to shoot as well as a Marine.
