I and Mrs 3T (it's her weapon) have run about 200 rds of various LR thru it now with no problem so maybe since Henry took back over they are solid now.
Or maybe we just got one of the good ones.
Either way they are fun and easily packable in her survival bag.
As much fun as my Springfield M6 Scout MM.
I forgot to add that it shoots about 2 inches to the right at 25 yards.
