I have a 6946 and I really like the fact that it has no safety to fumble and each pull of the trigger is the same and requires deliberate effort. I feel it is a very simple, yet safe firearm for personal defense. Would I love to have a 3953? Probably yes! The only issue with these DAO pistols is finding holsters that have a thumb break strap that will actually fit over the elongated slide. My 6946 does properly fit an old Gould & Goodrich pancake holster for the 59xx series as well as a Biancho Scorpio holster for the Beretta 92.
