In 2014 Sig Sauer introduced its first striker fired handgun into the market. Enter the Sig 320, a modular design, it boasts the ability to swap grip modules to different sizes allowing it to be fit to the users hands. The Sig 320 compact 9mm is also unique in that with a simple swap of the fire control unit you can swap calibers or even sizes from full size to a subcompact. This Sig Sauer 320 full size comes with 4.7" barrel and 2-17rd magazines. The Sig 320 full size comes with 3 dot tritium night sights for bright sight picture in all lighting conditions. The trigger on the Sig 320 full size 9mm is one of the best out of the box triggers on the market with a clean break and short reset for fast follow up shots. Like all 320s it has a 5-point safety system including a striker safety, 3-point takedown safety system, inability to disassemble without first removing the magazine, the system prohibits takedown without slide being locked to the rear, and lastly the takedown lever allows disassembly without use of tools or trigger manipulation.
