One reason the OHP went with the P320 over any Glock is that you can tear down the P320 without having to pull the trigger. It's modularity will also allow troopers to convert the gun from a full size to a carry size, compact size or subcompact size by simply moving the fire control unit from one grip module to the other and mounting the corresponding slide.Why did they not go glock or m&p? Both have know track records for reliability in the LE community. Not bashing the sig. It MIGHT be a better pistol.
