I have both. Well the LC9 is the LC9s.
If you are talking about the regular LC9, definitely take the Sig. The trigger on the old LC9 is terrible. If they both feel equally good to you I would still say take the Sig. More capacity in a very similar size and shape. Trigger on the LC9s is much better than the original LC9. Sig trigger is nice and doesnt have the safety blade thing. The flat trigger is even better (to me). For me the Sig felt a little too small so I bought an X frame and 12 and 15 round mags and it's a great ccw option now.
