(radically invasive projectile) from G2 Research. One interesting part about firearms examination is learning about all the various designs of ammunition, and it's another aspect that is constantly changing as ammunition designers try to get specific types of performance. One design choice for ammunition is loading a hollow point bullet into the cartridge (see the previous post about the terminology of ammunition if...]]></description><link>https://www.garrisonforensics.org/post/what-s-a-hollow-point</link><guid isPermaLink="false">6a0506ed93378d0be1157106</guid><pubDate>Thu, 14 May 2026 01:12:07 GMT</pubDate><enclosure url="https://static.wixstatic.com/media/8f060b_18234063235b44ef8347b29073889674~mv2.jpg/v1/fit/w_1000,h_1000,al_c,q_80/file.png" length="0" type="image/png"/><dc:creator>Kirk Garrison</dc:creator></item><item><title><![CDATA[Let's talk about printed Glock switches]]></title><description><![CDATA[This version of Glock switch is obvious to see. First and most important, they do work, at least for a time. They will not last as long as a metal version, but they are a small item to print, so the durability of them is not an issue. Once the blade of the Glock switch wears down, the firearm is still functional as well, just in it's standard semi-automatic function. There are two main versions of the Glock switch. The one I see most often is the one pictured to the left. This Glock switch...]]></description><link>https://www.garrisonforensics.org/post/let-s-talk-about-printed-glock-switches</link><guid isPermaLink="false">69f4e91890b4365cb860a08d</guid><pubDate>Fri, 01 May 2026 18:46:15 GMT</pubDate><enclosure url="https://static.wixstatic.com/media/8f060b_d23e993c791e4dec9bdfbccb4e413038~mv2.jpg/v1/fit/w_1000,h_1000,al_c,q_80/file.png" length="0" type="image/png"/><dc:creator>Kirk Garrison</dc:creator></item><item><title><![CDATA[The bullets go in the clip...right?]]></title><description><![CDATA[Pulled bullet and an intact cartridge If you want to utter terms that make a firearms examiner shiver (a phenomenon similar to saying splatter to a bloodstain pattern analyst) on the stand, continuously use the term bullet for cartridges and clip for ammunition magazine. We'll focus on cartridges for today. Bullet is used colloquially to name an unfired piece of ammunition for a firearm. Cartridge is the term a firearms examiner would prefer you use. Using bullet sets up the situation where...]]></description><link>https://www.garrisonforensics.org/post/the-bullets-go-in-the-clip-right</link><guid isPermaLink="false">69e4248543fd38a1bb73685e</guid><pubDate>Sun, 19 Apr 2026 01:39:35 GMT</pubDate><enclosure url="https://static.wixstatic.com/media/8f060b_53e467ecd7b24401a96e212360438295~mv2.jpg/v1/fit/w_1000,h_1000,al_c,q_80/file.png" length="0" type="image/png"/><dc:creator>Kirk Garrison</dc:creator></item><item><title><![CDATA[What is a class characteristic? Fired cartridge case example.]]></title><description><![CDATA[Top left moving clockwise: hemispherical (circle) smooth finish, hemispherical with turning marks, elliptical with rectangular firing pin aperture. This would be three easy eliminations. Class characteristics are the type of data that a firearm and toolmark examiner will use when they first start their comparison. These are generally pretty easy to see, and can be explained a viewed by a non-expert with little guidance. Sometime, as the example in the picture, it is as simple as a circle and...]]></description><link>https://www.garrisonforensics.org/post/what-is-a-class-characteristic-fired-cartridge-case-example</link><guid isPermaLink="false">69dadf8b75afb0779a7314c0</guid><pubDate>Tue, 14 Apr 2026 00:49:25 GMT</pubDate><enclosure url="https://static.wixstatic.com/media/8f060b_f2837e2a1e744df39bd283f9cc0450b6~mv2.jpg/v1/fit/w_1000,h_1000,al_c,q_80/file.png" length="0" type="image/png"/><dc:creator>Kirk Garrison</dc:creator></item><item><title><![CDATA[What if there is only a bullet? What general rifling characteristics can do for you.]]></title><description><![CDATA[FMJ vs TMJ (plated) fired bullets There are always hypotheticals and wiggle room in forensics, but especially when dealing with general rifling characteristics. Now, this does not mean general rifling characteristics examinations are useless. Like a lot of things in forensics, it is very dependent on the evidence. As mentioned in my first blog post about the inconclusive result for the bullet that killed Charlie Kirk, the condition of the evidence is always the first hurdle to overcome....]]></description><link>https://www.garrisonforensics.org/post/what-if-there-is-only-a-bullet-what-general-rifling-characteristics-can-do-for-you</link><guid isPermaLink="false">69d0745340e74dbec401fa1a</guid><pubDate>Sat, 04 Apr 2026 02:47:56 GMT</pubDate><enclosure url="https://static.wixstatic.com/media/8f060b_006c58fa9a7347689838de7d007b2315~mv2.jpg/v1/fit/w_1000,h_1000,al_c,q_80/file.png" length="0" type="image/png"/><dc:creator>Kirk Garrison</dc:creator></item><item><title><![CDATA["Bullet That Killed Charlie Kirk Doesn't Match Tyler Robinson's Rifle..." But what does this actually mean?]]></title><description><![CDATA[You look at your phone notifications and see this headline from People Magazine authored by Liam Quinn. The subheading reads, "Robinson's lawyers claim an ATF analysis failed to link the bullet to the rifle..." Reading this with no guidance, this seems like a case-closing piece of information. How can you continue to trial when the lethal bullet does not link back to the firearm of the suspect? Continuing to read, you come across the "need to know" section.
