“If we can deprive him of the ability to make his internal psychodrama a shared public reality, if we can break this ritual of violence and our own ritual response, then we might just banish these dreadful and all too frequent acts to the realm of vile fantasy.”

If you need some exceptionally deep penetrating ammo for your .38 revolver, I think I found your load.  More than 30″ of gelatin penetration!

 

 

Do you really need night sights?

20131111_024022

 

Paul Sharp writes a very informative article on night sights.  I agree.  They aren’t really necessary.  I don’t find them distracting like Paul does, but they are useful in a very limited number of situations.  The only time night sights will really help is when you have enough light to identify the target, but not enough to see your sights.  If you use a flashlight, your sights will be washed out.

 

Merry Christmas, Bob

01One of the most motivational articles I’ve ever read.  I like to re-read it every year around Christmas time.
