The basic idea of the Uxbridge Arms G6 is simple: Sometimes, people want a shotgun accessory to add to their rifle, typically for the purpose of door breaching (which is why they call them masterkeys). See Nick’s review of one such setup here , and there are plenty of others if you look around.
3D printing has now reached production handguns, and up to 30% less muzzle rise is the headline promise behind the P365-MACH3D. This is a micro-compact 9mm that SIG Sauer pitches with the line "Peak Performance. Everyday Carry."
NASA-supported human-factors research is not the usual starting point for a pistol grip, but it is where CZ's DiFEND methodology comes from, and it shaped the way the new CZ DUTY fits the hand. The rest of the pistol is just as deliberate. A serialized modular chassis holds everything together, a refined striker-fired trigger sits inside it, and the controls work for left- and right-handed shooters alike. The slide takes a red dot directly, with no adapter plates needed for four popular footprints. The CZ DUTY 4.0 lineup comes in four versions, with 15 or 17 rounds and with or without a manual safety.
Barrel-life specifications are a familiar sight in government solicitations, technical documents, and manufacturer literature, but what do they actually mean? A barrel rated for a certain number of rounds is not necessarily guaranteed to perform identically throughout that entire service life, and the terminology can be easy to misunderstand. With different definitions, testing methods, and performance standards involved, “barrel life” is often more nuanced than a single round count might suggest. I’ve seen plenty of confusion surrounding the subject, so this quick overview will break down what barrel-life figures represent, how they are established, and what they do, and don’t, tell you about a barrel’s expected service life.
