Another vote for the Beretta 950 Jetfire .25. Granted, not the most effective caliber. But it's a proven, safe and reliable design. As reliable as any auto pistol I've used. Small & light weight. 8+1 ammo capacity. I know - shame, shame - but it's proved to be the most "carried" gun I have.
I've toyed with getting a Kel-Tech P-32, but I've just read too many horror stories - and I have never really actually seen one used on the fireing range (carried a lot - shot a little I suppose). Have seen the Beretta Tomcat .32 in use - accurate & no problems. But it's fairly heavy & chunky. Might as well go with a 100% reliable ultra-light .38 as one of those.
