Definitely a no. If you could mold a u shaped piece of leather to wrap around from the front of the trigger guard to the back, then that would make that a very nice holster.
I would, but I don't carry in condition one (loaded chamber). If I were so inclined to carry with a loaded chamber, I don't think this would be a set-up I'd choose.
I have a CW9 and several other handguns that I carry from time to time that have various trigger actions. I personally want the trigger completely covered by my holster regardless of the action or safety on/off condition. Guns are dangerous enough as it is. Keep that trigger buried.
I not only would use it... I have worn one very similar while working undercover. It actually works pretty good... Although I probably wouldnt use it for a condition one carry.
