Product Description: The Wilson Combat 09400115SPFC Xtreme Defense lead free Fluid Transfer Monolithic (XD FTM) heralds a revolutionary shift in the perception of self-defense bullets. Similar to the Xtreme Penetrator, it features a progressive nose geometry that facilitates deep, straightforward penetration and creates a permanent wound cavity with a diameter that surpasses that of most expanding bullets. This unique bullet is composed entirely of copper, an attribute which not only enhances its ability to penetrate barriers but also makes it environmentally friendly. Furthermore, it inflicts severe tissue damage upon impact. Its performance is not negatively affected when it penetrates barriers such as drywall or heavy clothing before hitting the intended target, a common issue with traditional hollow point bullets.
