9mm Controlled Fracturing 115-Grain Bullet by Lehigh Defense - Slow Motion Gel

This video provides a clear, demonstrative comparison of 9mm FMJ versus R.I.P. ammunition performance. Utilizing a Sig Sauer M17 and slow-motion videography, the test shows the distinct impact characteristics of each round on a clay block. The R.I.P. round exhibits a significantly more destructive and fragmenting effect compared to the standard FMJ.

Instruction from Ted of Line 45 provides expert insights into building an ammunition stockpile before potential shortages. The guide details which calibers are most vulnerable, like .22 LR and 9mm, and explains the impact of supply chains and import restrictions. It emphasizes strategic stockpiling for different uses, from training to self-defense, to ensure preparedness.

This video explores the growing trend of shooters replacing 9mm with alternative calibers in 2025, driven by advancements in ammunition and firearm technology. The presenter, Ted from Line 45, details the strengths of .30 Super Carry for concealed carriers seeking higher capacity in compact frames, 5.7x28mm for its flat trajectory and speed, 10mm for its significant power and barrier penetration, .357 SIG for its velocity and hard target performance, and .22 TCM for its rifle-like speed in a pistol platform. The discussion highlights how these calibers address specific needs that 9mm may not always meet, emphasizing performance, capacity, and specialized applications.

This video conducts a ballistic gel test comparing two .38 Super self-defense ammunition types: Colt Defense (DoubleTap) 124gr JHP and Lehigh Defense 115gr Controlled Fracturing. The test, performed from a Colt Gold Cup National Match 1911, reveals significant differences in terminal performance. The Colt ammunition failed to expand, tumbling and exiting the gel block with no expansion, while the Lehigh ammunition fractured as designed, with its fragments and core achieving substantial penetration and spread.

This video demonstrates the unique properties of blue tip 9mm ammunition, which is designed to explode on soft target impact. The instructor, exhibiting experienced authority, tests this ammunition on various soft targets, including simulated zombie heads and soft earth, showcasing its potential applications in extreme scenarios. The guide details how to safely test and observe the effects of this specialized ammunition.

This video provides an expert-level analysis of the .45 ACP cartridge's effectiveness, comparing it to 9mm. It delves into the historical context of its design by John Browning, its ballistics, and its performance in modern contexts. The analysis debunks myths like 'knockdown power' and emphasizes that shot placement, penetration, and expansion are key factors, with modern ammunition narrowing the performance gap between calibers. The video concludes that .45 ACP remains a viable and effective cartridge, especially for suppressed use, but stresses that shooter skill and training are paramount.

This guide details the dangers of 'thumbing the hammer down' on a loaded firearm, a technique strongly advised against by experts. It emphasizes that this action, which involves pulling the trigger while manually lowering the hammer, carries a high risk of accidental discharge if the thumb slips. The expert instruction highlights safer alternatives like engaging the manual safety for 'cocked and locked' carry or clearing the chamber entirely.

This guide details the advanced technique of hand stippling a 1911 firearm frame for enhanced grip, as demonstrated by a master gunsmith. It covers the precise application of texture using a punch and hammer, followed by meticulous filing to refine the edges. This process requires significant skill and attention to detail for a professional finish.

This guide details the proper technique for cycling the slide on a semi-automatic pistol, specifically the 1911, as explained by Ken Hackathorn. It emphasizes avoiding "gun abuse" by not slamming the slide on an empty chamber, which can cause premature wear. The explanation includes the mechanical reasons behind this, focusing on how the cartridge rim stabilizes the extractor and cushions the slide's action.

Massad Ayoob, a renowned firearms instructor and legal expert, details the critical post-Defensive Gun Use (DGU) protocol. He emphasizes that the most common mistake is failing to immediately call 911 after a DGU, even if no shots were fired. This action is crucial for establishing oneself as the victim complainant in the ensuing legal aftermath.
