S&W stock trigger is actually not bad, although I can definitely tell the difference with the Apex trigger kit, sear and all. (shorter reset and lighter pull) As for the Pearce grip extensions go, I really like the ability to get a full overlaping grip with both hand, (no hanging pinky and solid follow up shots). I typically use an IWB from Multi Holster and haven"t had any issues with the extension. The CT Laser is ridiculously consuming, I started finding myself searching for the light tonight instead of a repeating sight picture. I had to stop myself and regroup my thoughts and procedures for a quick start and target lock. TFX sights work great in reduced light (smoke filled indoor range). Had 45 unloading at a ridiculous rate in the next stall with no issues.
