The article you read is correct with regard to the 147 gr load. The 147 gr JHP is better than FMJ's but it is not the best load for the 9mm. The 147 gr load was originally designed for use in suppressed sub-guns. The 115 gr +P+ and 124 gr +P loads are better choices for a handgun. There are several manufactures offering these loads. Choose a load that feeds reliably and shoots accurately in your weapon.
