Depending on how I am dressed there are 3 in the normal rotation:
1. Glock 21 .45
2. S&W 66 3" .357
3. S&W 638 .38
I once had a Taurus .45, but it had a few problems. Once or twice per 10-round mag I could squeeze the trigger back all the way, as far as it would go, and nothing would happen. Then, when I released the trigger, BANG. Also, the magazine would eject on its on every few rounds. After three trips to Taurus they finally fixed it, but I decided it was not going to be a keeper. It had good ergonomics. Sure felt good in my hand. I'll stick with the three I have listed above.
