I've decided to sell my Springfield XDS and replace it either with a Glock 26 Gen 4 or Glock 27, Gen 4. While I'm sold on the platform (as I already own a G19 and love it), I'm having a hard time deciding which caliber to buy. I plan to shoot and likely carry either gun in 9mm. Either buy the G26 or the G27 with a conversion barrel. I would typically go straight for the G26 due to it being a factory 9mm, but I like the idea of shooting the 9mm, .40 cal, or .357 SIG out of the same gun. I guess my question is: How reliable is the G27 with a good conversion barrel? Is it reliable enough to trust your life to? And is it worth buying the 27 to have the ability to shoot 3 calibers?
