Q&A #4: These Are A Few of My Favorite Things

Published on March 24, 2016
Duration: 54:47

This Q&A session covers a range of firearms topics, from the failure of the XM8 rifle due to cost-effectiveness concerns to the historical reasons for continued revolver use in WWII. Ian McCollum discusses the technical nuances of firearm nomenclature, the practical issues of 1911 hammer bite, and the limitations of flechette ammunition. He also shares personal favorites from his collection and offers insights into the future of 3D-printed firearms and the plateau of modern firearm design.

Quick Summary

The XM8 rifle program failed because it didn't offer a significant enough improvement over the M16/M4 to justify the massive replacement cost. Flechette ammunition also proved impractical due to poor accuracy and barrier penetration. Firearm technology has plateaued, requiring new propellant or projectile tech for major advancements.

Frequently Asked Questions

Why did the XM8 rifle program fail?

The XM8 rifle program failed primarily because it did not offer a significant enough improvement over the existing M16/M4 platform to justify the massive cost of replacing the entire U.S. military's small arms inventory. The goal was a 100% improvement, which the XM8 did not meet.

What is 'hammer bite' on a 1911 pistol?

Hammer bite refers to the issue on original 1911 designs where the hammer or slide can pinch the shooter's hand during recoil. This led to the development of modern beavertail grip safeties to prevent the slide from contacting the web of the hand.

Were flechette rounds effective in military trials?

No, flechette rounds were largely unsuccessful in military trials. While theoretically offering higher hit probability, they suffered from poor accuracy at range, terrible barrier penetration, and inconsistent wounding potential compared to traditional bullets.

Why did some nations continue using revolvers in WWII?

Britain and other nations continued using revolvers in WWII mainly due to the prohibitive cost and logistical challenges of replacing their vast existing inventories of revolvers with semi-automatic pistols. It was more economical to maintain the status quo.

What is the future of 3D printed firearms?

While polymer 3D printing is an interesting experiment, metal 3D printing is seen as the future for firearms. It offers potential for reproducing rare parts and enabling the creation of complex new firearm geometries that are difficult or impossible with traditional manufacturing methods.
