Ergonomics, ergonomics, ergonomics, in that order. Most of the compact offerings by the major companies are going to be accurate, enough. Light, enough and shoot well, enough. It really comes down to which gun feels the best in the hand and that you shoot well. I would say to hold back onb any offering by Ruger right now, their QC has been horrendous.
mwc is spot on here. In a SD situation, you probably
won't have the time to use the sights, so how the gun fits is of paramount importance. If you have enough time and distance to require sights, an unfriendly prosecutor could argue that you could have done something different....
IMHO, this is another argument in favor of the revolver - the choices in aftermarket grips is enormous - size, angles, covered or exposed back-strap, wood, plastic, hard or soft rubber, round butt to square butt, etc. You WILL find one to make the revolver an extension of your hand rather than something you're holding. With a semi-auto pistol, you are pretty much limited to what is there originally - the grip has to go around the magazine. True, you can get aftermarket grips for an auto, but you are still limited by the magazine size.
Ammunition, too, is another consideration. Self-shuckers need a certain minimum power of ammo to function reliably. If that level is uncomfortable to shoot - think trigger jerking and flinching here - you're stuck with it. Some small frame revolvers can handle everything from mild (but still effective) target loads through .357 Mag. (though I can't imagine why anyone would want to touch off one of those) without a hitch. You can tailor your choice in ammo to optimize holes in target.
As for lasers and other gizmos and geedaws - the money you spend on one of those will buy enough ammo to really become proficient at point shooting.
"I am still leaning towards a revolver because I feel the most comfortable with them. Using a gun is a last resort and my AO is a very low risk area. So, 5 well placed shots from a j frame or lcr should do the trick with proper ammo if necessary in all seasons." Go with your gut - you will not be under-armed.
