Letter Re: .40 S&W to 9mm Conversion Barrel for a Glock Model 23?

Well I thought I would write a quick note concerning the shooting of  9mm [Parabellum] in a Glock 23 after you’ve changed the barrel. Some say that it will work most of the time. Why would you ever do something to a firearm which only works most of the time? It is not only very stupid it is also unsafe, one of the reasons being the different ejectors between a 9mm and a 40 S&W. I for one know that the time I needed the firearm the most it would not work. Please, if you want to shoot a 9mm Glock then buy a 9mm Glock. I am a Glock armorer and yes I own several Glocks but I don’t try to do things with my guns that they we not designed to do. I have a 12 pound short handled hammer that I can use to drive a square peg into a round hole–but that doesn’t make it right. – The Mailman
