Per this caller, my G27 is .40cal but I can drop a .357 Sig and a 9mm barrel in it and it works flawlessly.
Pretty sure I posted that before but Tom forgot to tell that caller he has 3 guns in one.
Yep, he missed that multi-change barrel option. I have 500-rnds of Cor-Bon .357sig 125gr HP in my basement stocks. I’ve decided to keep it.
