Have you checked the reliability of critical defense ammunition you have selected? For 9mm ammunition in particular new technology is providing more options than ever before. Critical Defense ammunition must provide the expansion, penetration and quality to protect you and others during a dangerous encounter. What many firearm owners forget is…will the ammunition cycle properly through my firearm. I recommend you purchase several different brand and styles of critical defense ammunition and get to the range to ensure that your firearm will properly cycle with your selected ammunition. I know from range experience that not all firearms like the same ammunition. Stay safe and test fire your critical defense ammunition.
