Or could you live without them? I am a couple of weeks away from ordering a P220 or P220c and it will be used mostly for a house gun, occasional carry gun. The gun will be in my night stand with a Streamlight TL-3 packed with rechargeable lithiums. With all that being said I would think that with the light disorientating the would be attacker this would be the way to go. Some would probably argue that the light gives the perp. a target. This may be true but I would be holding the light away from my body thinking that I would not make myself an accurate target. Besides, since I know the floor plan like the back of my hand I would not turn on the light until the last minute.
Of course if the perp. could get by my 120# Rhodesian Ridgeback, more power to him, I will be waiting.
I guess what I am getting at is I am pretty sure the Sig comes with a “Post” for it’s front sight? I believe the night sights come with dots front and back and I have read that sometimes this could be a confusing thing for some folks who like me are used to the more traditional “Post” or “Blade” as some folks would call them.
