Mas - In an earlier thread you addressed a writers' concern about his first handgun purchase ... he was deciding between a 9mm and .40 caliber. I was puzzled by your final response, that you'd feel better protected by a 9mm with 124+P or 127+P+ hollow points (I believe you suggested Gold Dot) than you would with subsonic 180 grain .40 caliber ammo. Why have you chosen to promote 155 or 165 in .40 caliber compared to the 180 grain round that was the basis for the development of the entire .40 caliber platform? It's my understanding that the FBI uses the 180 grain round, as do many other federal law enforcement agencies, and a friend of mine who just retired from the Border Patrol says they are going to be adopting the 180 grain round also. In a conversation I had with a technician at Glock, he also recommended the 180 grain round because he says Glock developed their .40 caliber guns around that weight bullet. Have you learned from the street that the 180 grain round is deficient in stopping the aggressors out there? Thanks in advance for your thoughtful response.
