Just received my 9mm barrel, so took some 9mm and some .410 ammo to the range on Saturday. After going through a box of 9mm, marveling at how accurate this fine piece of machinery is, I swapped barrels and loaded up what, will ultimately be, my defensive round of choice. After 4 rounds, I packed up my stuff and went home… I had heard that the .410 round was not for the faint of heart when it comes to this size firearm, but you just don’t appreciate it until you wrangle with it first-hand. Still rather be on the ‘giving’ than the ‘receiving’ end of a .410 round coming out of this extremely well-built piece of American exceptionalism! The only issue that I ran into was that the trigger guard worked itself loose during this visit to the range. I thought that might be a little odd, since I had gone over the gun prior to firing it with a fine-tooth comb and made sure everything was good and tight.
