For dedicated CCW, I'd recommend spurless with the short barrel. Crimson trace is fine if you got the money to burn but not necessary and some would argue, not adviseable. the shorter barrel with spurred hammer is just a bit easier to conceal and carry than one with a hammer and/or longer barrel.
The hammer is a wasted piece of furniture on a dedicated CCW gun. you'll never take the time to cock it. If you're trying to be so careful as to want to cock it into single action for a hostage situation or some jazz then you're dreaming, have the wrong gun, and are quite possibly outside your legal rights.
Now if you want to also use this as a field gun for hiking, fishing, etc and CCW, then I'd recommend the longer barrel and a hammer.
Either way I'd recommend a reduced main spring that costs $8 and takes 5 minutes to install. It'll greatly improve the double action trigger pull of this fine gun.
Final option, get the spurless, short barreled version, send it to Gemini Customs to make it a beautiful and functional work of art. Then buy the long barreled version with a hammer and leave it stock as a working, bang around field gun. :yup:
