I was a revolver guy as well...Had a Ruger single action in .357...I was at the range one day (about 25 years ago) and a guy had a Ruger MK-II, I shot it a few times and loved it...Got me one in the 6 7/8 med heavy stainless...After I used it a while I realized that by not putting one in the chamber it might even be safer than a revolver and carring an extra clip made reloads faster...

About 10-12 years ago I took the class for concealed carry...The instructor was a deputy sheriff...One evening, I asked him his recommendation on a good defense handgun...He carried a Glock in .45...

I ended up with a Glock 23, which is a .40...It will cost you around $500, but I feel like it's a good choice...My brother carries a 38 hammerless snub...He thinks my Glock is a little large for CC, but, in this case, I'd rather have more than needed....
