TDC you read to many ads. Last time I looked Police Departments carry Glock parts for a reason. Glocks are very good service pistols no doubt but really what evidence do you have they break less than any other pistol. JR from the Shooting Edge has posted on this forum about his experiences with Glocks and I don't recall Glocks being significantly better than other pistols The Shooting Edge rents out. As to reliability, isn't there a Youtube video of a Glock's inability to handle limp wristing.
We all like our guns and have bought them for a reason. Some buy because LEO's used them, which is great of you are a cop whose department has budget restraints but hardly a reason to buy a Glock if you like shooting tin cans or shoot competitively in Bullseye shooting. Others buy their guns because the top shooter in the sport they have chosen wins with them. It all really becomes very subjective and very personal, hence the passsion.
