I have never been a big fan of the 40 S&W round.I got rid of my last 40 last month because I have just not been able to shoot the 40 very well compared to my other calibers. As of this month I no longer had a 40 or a Glock. But yesterday I made a trade for a Glock 23 with a co worker.I can shoot this gun better than any 40 I have ever shot.I like it so much I shot 850 rounds out of it the first day I had it. I am now going to use it in my Defensive Class this summer and I am going to use it as my Primary Carry Gun. I am in love with a 40 for the first time ever. I am a happy man!!!!
