Spores != bacteria.  Further, can kill is not the same as sterilize, so yes a handgun can kill some bacteria in much the same way a bullet wound kills some skin cells.<p>They are probably less susceptible to <a href="https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Hydrostatic_shock" rel="nofollow">https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Hydrostatic_shock</a> though.<p>Though, without actually sterilizing a sample it can be difficult to notice, but lot&#x27;s of things kill bacteria.  They are easy to kill, but hard to kill off.<p>PS: <i>Spore formation in bacteria is not the principal method of reproduction but simply a method of surviving unfavourable conditions.</i> They are like pinecones which can survive forest fires while pine trees tend to burn really easily.
