Iver Johnson Prototype .25ACP Blow Forward Pocket Pistol

This video examines a unique 1916 prototype blow-forward .25 ACP pistol from Iver Johnson. The firearm is a one-of-a-kind tool room sample or demonstration model, based on a patent applied for by William O. Barnes in 1912 and granted in 1916. Iver Johnson, known primarily for revolvers, appears to have considered this semi-automatic design but ultimately did not put it into production.

This video highlights the Walther TPH .22 LR pistol, dubbing it the 'King of Mouse Guns.' It notes the pistol's 6+1 magazine capacity and its availability in .25 ACP.

This review of the Beretta 21 A Bobcat in .25 ACP, presented by an expert from GUNS and American Handgunner Magazines, details a live-fire accuracy test. The expert demonstrates shooting at 15 yards, analyzes the resulting group, and discusses potential gunsmithing modifications to enhance accuracy, specifically suggesting the addition of adjustable sights. The assessment highlights the pistol's fixed sights and offers insights into its practical performance with specific ammunition.

This video provides a review of the Beretta 21A chambered in .25 ACP, highlighting its characteristics as a 'gentleman's pocket pistol'. The reviewer notes its compact size, though emphasizes it barely fits in a pocket, and mentions the "almost non-existent" sights. Despite these drawbacks, the pistol is praised for being a pleasure to shoot, extremely well-made, comfortable, and having no recoil. The review touches upon its Italian classic heritage and its US manufacturing to circumvent the Gun Control Act of 1964. It also points out the continued availability of magazines and .25 Auto ammunition.

This video provides an expert-level ballistic gel test comparing Hornady Critical Defense (FTX) and Hornady Custom (XTP) .25 ACP ammunition. The host, demonstrating high authority and expertise, uses a Beretta 21A Bobcat and a LabRadar chronograph to meticulously analyze terminal ballistics, including velocity, penetration, and projectile expansion. The findings suggest .25 ACP is an underpowered caliber for self-defense, with neither tested hollow-point round expanding effectively.

This review tests the lethality of various pocket pistol calibers by simulating different scenarios. Initial tests show even small rimfire and .25 ACP rounds penetrate plywood, but a ceramic tile barrier stops them. Ballistic gel tests reveal significant differences in penetration and wound channels, with modern JHP and +P loads outperforming standard FMJ, especially in .25 ACP and .380 ACP.
