  Can't speak for everyone but the "ramblings" are one of the reasons I really enjoy this channel.

  “It’s drop safe because it goes out of battery” that’s when my p320 took offense and exploded on me.

  “They bought the design. Then they showed it to their engineers. And they said “oh no”. <br><br>PSA is getting flashbacks to their STG-44 re-design.

  The Hudson H9 looked cool and different with that large dust cover. &nbsp;It looked a little sci-fi. &nbsp;Daniel Defense fixed the problems, but in doing so made it look like any other 9mm on the market, and at the price of $1,300.00. &nbsp;It has a lot of competition. &nbsp;$200 more and you can have a FK BRNO PSD-C that can convert between 9mm 10mm and 7.5 FK rounds, scratch the itch for a different looking cool gun, and get to shoot the 7.5 FK round with it&apos;s interesting characteristics.

  That was a fair number of malfunctions in a relatively small number of rounds.

  I’m Hudson sir, he’s Hicks.

  That was a scary number of malfunctions for a $1200 pistol.

  The idea that DD could’ve bought the H9 without their engineers looking at it first is comical

  I recall that Tony Neophytou had a really good tidbit of wisdom when he described his approach to firearms design: He started his designs from a consideration of spring design. Neophytou very wisely points out that the springs in a gun are the &quot;living parts&quot; of the gun. I think what he is getting at is that the springs are the primary energy management components in a gun. Springs absorb and store recoil energy required to chamber the next round and bring it back into battery. <br><br>It turns out that if you want a spring to last for many cycles, you cannot design it to be compressed to close to it&apos;s yield strength. Basically if you design your spring such that it is close to the yield point of the metal by the time it&apos;s fully compressed, you risk fatigue failure of the spring. If you want high fatigue cycle life you basically want to be working at half the stress level for the metal.<br><br>This means that you have to allow considerably more storage space for a longer, smaller diameter wire, coil spring that is expected to be working at about 40% of it&apos;s yield stress for durable cycling.<br><br>I see that in firearms design, there is a tendency to fixate on the mechanical clockwork aspects of a gun and work out the springs later. The springs, appearing to be compliant squishy things look forgiving, but it turns out that it is not difficult to invest a lot of time in clockwork design only to find out that you didn&apos;t leave enough space for springs. <br><br>You&apos;ll see these signs of a struggle in areas like a double wound AK extractor spring which has three strands of wire twisted together before they were wound into a coil spring. They had to reduce the wire diameter to reduce stress in the metal when it deflects, but they also needed 3x the axial force so they had to triple up a small dia wire to get the necessary force without the high stress of larger dia wire. <br><br>CAD is great at helping designers lay out clockwork, but it&apos;s easy to forget to consider the life of the springs and get lost in the cams and sliders. A complete designer will also use spring design calculator software to see if their springs are working within durable limits, but CAD systems don&apos;t usually offer these features directly so springs get forgotten about in many mechanism designs.<br><br>Adept designers tend to be clockwork designers. They tend to focus on the phases of motions in cam slider blocks and locking mechanisms. Veteran designers think about dynamic issues like inertia and energy management.

  Hudson&apos;s biggest misstep was not naming it the Hudson Hawk.. &nbsp;that would have saved the business!
