The only way to make a reasoned decision is through repetition, as in shoot it and shoot it some more! I recommend using FMJ and the self defense(SD) ammo you will be carrying.
I had a SW40VE, the Sigma 40 with a similar long trigger, and ended up leaving it alone. It's a great gun for self defense, the trigger pull is designed long and hard as a safety mechanism. If you're going to use the weapon as it is intended ( SD stands for Self Defense), then don't monkey with the trigger. IF you want to turn it into an accurate range weapon, THEN look into trigger mods, or buy a pistol designed for SA fire ( like my SigSauers , for example ) that have a light and smooth SA trigger. One gun is not going to excell at every use.
