I applaud you on your thinking to go with a "safety less" handgun for SD purposes. MANY of them, Glock and Sig being two VERY nice systems along with others have no safety "Lever" at all. Yes some do have the "Safety in the Trigger" but I personally would not call this a safety.

I daily carry (SD and at work) a Ruger LC9 with CTC laser guard and it is a double action with a manual safety. The trigger pull is LONG, but smooth and not really that overly heavy to me and I carry it with the manual safety off! It is always in a holster on my belt so I don' feel unsafe at all. Others may claim this is dangerous, but I am accustomed to pulling and firing and if I had to deactivate a safety in a real world situation I could easily fumble it or forget it. I would rather trust in training and familiarity. Just me, and your mileage may vary.
