I thought exactly the same thing. The SA/DA is particularly worthwhile IMHO for LE and civilians if they already own a Sig or another SA/DA weapon. The learning curve is short and the SA break is sweet. Plus, with practice that first DA shot (if you so elect) can be as accurate and as instinctive as the follow on SA. IMHO both the the SA/DA is well suited for ALL shooters. And I might add that Sig sells a boatload of SA/DA guns to both LE and civilians. My federal agency's issue weapon is a Sig P229 SA/DA and it continues to serve us well. My personal guns are a Sig P239 SA/DA and P2000 both in SA/DA. With practice comes proficiency and safe handling. And in a lot of cases, civilians get more practice (by choice) and are more knowledgeable about guns than LE. Nothing wrong with the LEM either.Why would DA/SA be good for a cop as opposed to a non law enforcement person? I personally like the short and light trigger pull of SA for quicker follow up shots. I thought Law enforcement agencies (some) require or prefer DAO, or LEM, to reduce the chance of accidental discharge in situations of high stress where the officer might accidently depress the trigger if it were single action.
