A 1911 is an excellent EDC and when properly maintained I will trust it with my life every day for SD. However, my SHTF sidearm is a Glock because in that situation being able to do proper cleaning and care is a serious question. It's also set up to be primarily a 9mm, but can also us 40S&W. Why do I use a 45 for SD, but 9mm for SHTF? Because there is a big difference between SD and a firefight. In SD the first few rounds almost always determine the outcome, so I want a powerful round. In a firefight, capacity of the weapon is much more important, so I use a high cap. This also means that between the two weapons I can use any one of the three most popular handgun rounds. Different weapons for different jobs based on objective logic.
damn....your a master carry guy. Bet you keep Mustangs in your boots.
