The bottom of my list:
Worst, a Taurus Millenium Pro PT-145. Terrible trigger. DAO so you couldn't get away from the poor trigger.
Next, a Kel-Tec P-11. This one as a gun was a tie with the Mil-Pro, but because it was given to me, it ranks next to worst. Another terrible trigger, DAO, sights so poor you might as well not use them, cheap piece of junk.
3rd worst, a Taurus 24/7 compact .45. I thought it might be better than the Mil-Pro. It was in that it was SA/DA. A little more accurate, but not much. Sights were off 10" at 12 yards.
Good thing is, there's always someone looking for a belly gun. These fit right in.
I came across a Glock 30, that did all the things I wanted of a SD sidearm, and did them all reliably and well. It may cost more, but it's worth every penny!
