Details, but those are important when talking about classics.&lt;p&gt;Better animation:
&lt;a href=&quot;https://www.youtube.com/watch?v=E6SmlOEzNBs&quot; rel=&quot;nofollow&quot;&gt;https:&amp;#x2F;&amp;#x2F;www.youtube.com&amp;#x2F;watch?v=E6SmlOEzNBs&lt;/a&gt;&lt;p&gt;Watch the barrel.  In the OP the entire barrel floats up and down slightly.  That&amp;#x27;s incorrect.  The breech end of the barrel moves up and down, the other end not so much.  This is important because the angle between the barrel and the next round doesn&amp;#x27;t change in the former.  Check the vid at about 3:24, after the assembly, to see what I&amp;#x27;m talking about.&lt;p&gt;Also: &lt;a href=&quot;https://www.youtube.com/watch?v=YKRMcTlbWTs&quot; rel=&quot;nofollow&quot;&gt;https:&amp;#x2F;&amp;#x2F;www.youtube.com&amp;#x2F;watch?v=YKRMcTlbWTs&lt;/a&gt;&lt;p&gt;And the recoil animation is wrong.  The gun in the OP is recoiling while the bullet is still in the barrel.  That&amp;#x27;s logical, but in reality recoil only gets going after the bullet is away.  Once it&amp;#x27;s out of the way the remaining propellants really accelerate, causing the bulk of the recoil.  That&amp;#x27;s why recoil doesn&amp;#x27;t impact accuracy.  Flinching in anticipation of recoil is another matter.&lt;p&gt;Watch this gun at 00:10 and note it doesn&amp;#x27;t move until the bullet is long gone.&lt;p&gt;&lt;a href=&quot;https://www.youtube.com/watch?v=Um9Eos9bJDk&quot; rel=&quot;nofollow&quot;&gt;https:&amp;#x2F;&amp;#x2F;www.youtube.com&amp;#x2F;watch?v=Um9Eos9bJDk&lt;/a&gt;&lt;p&gt;Proper 1911 recoil animation: &lt;a href=&quot;https://www.youtube.com/watch?v=1H3IFJXxyEs&amp;amp;list=PL1469B47BBD916A46&quot; rel=&quot;nofollow&quot;&gt;https:&amp;#x2F;&amp;#x2F;www.youtube.com&amp;#x2F;watch?v=1H3IFJXxyEs&amp;amp;list=PL1469B47BB...&lt;/a&gt;</text><parent_chain></parent_chain></comment><story><title>How a Handgun Works: 1911 .45</title><url>http://animagraffs.com/how-a-handgun-works-1911-45/</url></story>
