I agree with Mr. DeShivs. The double-barreled derringer is 19th century technology that is mostly outdated. Compare the Roughneck chambered in .45 Auto to a relevant pocketable piece of 21st century technology, the Ruger LCP MAX chambered in .380 ACP:
• the LCP MAX has 450% more capacity — 11 rounds vs 2 rounds;
• the LCP MAX has 150% more tissue destruction potential — as measured by a modification to the Taylor Knock Out Factor, mTKOF, muzzle energy (instead of momentum) multiplied by bullet cross-sectional area (instead of diameter) multiplied by capacity, where the LCP MAX has 0.0097 ft^3•lb•rounds vs 0.0039 for the Roughneck (the .45 ACP beats the .380 ACP hands down on a cartridge-to-cartridge performance, but 11 rounds of .380 ACP is better than 2 rounds of .45 ACP);
• the LCP MAX has 53% less recoil — 4.8 ft•lb vs 10.2 ft•lb;
• the LCP MAX weighs 44% less — 0.66 lb vs 1.19 lb (each unloaded);
• the LCP MAX has 23% less bulk — about 7.9 in^3 vs 10.3 in^3 (B ≈ LWH/2); and,
• the LCP MAX has a 33% greater muzzle velocity — 937 ft/s vs 703 ft/s (thus, a flatter trajectory should you ever need to socially engage with your pocket piece at beyond bad breath distance).
The only metric the Roughneck outperforms the LCP MAX in is MSRP — $269 vs $449. But, for twice the price the LCP MAX is more concealable, easier to carry, harder hitting, and more accurate. These days the derringer is best relegated to the role of BUTTBUG, Back Up To The Back Up Gun.
