Videos tagged with Tight Tolerances

The primary issue with double stack 1911 and 2011 pistols is potential reliability problems stemming from their extremely tight tolerances. While this design contributes to a smooth action, it leaves minimal room for error, making them susceptible to malfunctions when exposed to debris or after high round counts. This trade-off means these high-precision firearms may perform less reliably in adverse environmental conditions.

This video provides an in-depth review of the Les Baer Custom Carry Blued 1911 pistol. The presenter highlights its exceptional fit and finish, noting the 'ultra tight' tolerances that contribute to a hard rack but also a smooth shooting experience. Performance with Sig Sauer 45 ACP ammunition and Wilson Combat magazines is discussed, along with praise for the pistol's trigger and aftermarket Lock Grips.

This review covers the Ed Brown Special Forces 1911 in .45 ACP, highlighting its premium features and performance. The firearm boasts a smooth stainless steel finish, beveled edges, G10 grips with a chain-link pattern, and a fiber optic front sight. The presenter emphasizes the exceptional fit and finish, noting the slide's smooth action and tight tolerances. Initial shooting impressions reveal a sensitive trigger with minimal reset, contributing to a positive shooting experience. After approximately 100 rounds, the firearm demonstrated reliable performance with only one minor failure to feed attributed to limp-wristing.

This video tours the Smith & Wesson factory in Springfield, Massachusetts, highlighting their advanced manufacturing processes for M&P pistols and rifles. It emphasizes the use of sophisticated CNC machinery with automated tool loading and measurement, as well as Computerized Measuring Machines (CMMs) to maintain extremely tight tolerances (plus or minus a tenth of a thousandth of an inch). The assembly process is described as a 'quality checkline' with multiple inspection points to ensure high-quality, reliable firearms.

This video details the manufacturing process and benefits of Nowlin 1911 barrels, emphasizing their Electro Chemical Machining (ECM) technique for superior accuracy, smooth finish, and stress-free rifling. It covers the advantages of tight tolerances and tighter-than-normal rifling for better bullet seal, leading to higher velocity and less fouling, making them ideal for high-volume shooting. The guide also explains the differences between drop-in and gunsmith-fit barrels, including fitting procedures for optimal lock-up, and highlights the availability of various calibers, lengths, and the Nowlin ramp feature for enhanced case support.
