Lights are a good thing. Now I don't have a light on my carry gun but I do on my house guns. Let's face it gun guys/gals like gear. So what types of accessories would I recommend investing in first:
1) Good belt and holster
2) Quality handheld EDC flashlight
3) Upgraded sights and/or trigger
4) weapon mounted light for HD gun
5) laser grips
Notice I mentioned I own laser grips earlier. Also notice where I put it in priority. The exception being a small revolver that does not require a heavy belt to carry, has no way to mount night sights and no way to mount a light. Hard to beat a J-frame with a good trigger job and crimson trace grips.
Hey, stop makng me agree with you. I would have a laser on my j frame for the very reason you mention (poor sights), but from what I have heard they are not exactly well suited for a lefty.
