I found this bit of information floating around the internet. "Be advised that we recommend the +P cartridge for use only in compact handguns with barrel lengths less than 4-inches. The 124-grain Gold Dot bullet seems to provide optimal penetration and expansion performance when propelled at approximately 1150 fps. The +P load is designed to propel its bullet at 1220 fps, and this could lead to over-expansion and under-penetration when fired out of a handgun with a barrel length that is 4-inches or longer." This is confusing. Would it be advised to use regular 124grain Gold Dot instead of the +p offering in full size service pistols such as the Glock G17 or the Sig P226? What is your take on this?
