Lines of Effort
Effort Pistolshell is the development of a plastic brick shell for popular handguns that would allow easier attachment of accessories than the handgun now allows, and/or the addition of a shoulder stock if a 16" bbl is available for the handgun in question, or if a SBR tax stamp has been purchased.
Please do not send pictures or videos of your firearm in an illegal configuration; ie, a US pistol, without a 16" barrel, with a stock installed. Such emails will be immediately forwarded to the BATFE with all of your contact information. If you've spent the money on a tax stamp, be sure to include a scanned tax stamp with your pictures - it will not be posted. If you live in a nation where such toys are legal, by all means.
