You sound like you are posting on Gunbroker. LOL!
OT, did you know I can change out my G27 40cal with a 9mm and .357sig barrel and only have to change two magazines? It’s 3 guns in one!
Yes, my G32 changes .40cal barrels out too, and uses same mags. G32’s .357sig is a flatter trajectory and harder cavitating round than .40cal. It was my first gun right after 9-11-01, and I carried it for 2 yrs, until I found Kimber 1911s. I still have the classic 1974 Colt Trooper MK III .357mag, plus all my Class IIIs, Henry Big Boy in .357mag, .50, 2 Remy 12s.
That accessorized Glock is the last choice piece I’m letting go.
