A quick search shows that recommended min/max OAL is 1.085"/1.135" for .40
However if your duty ammo is 3 years old, it should be replaced. Will it work, probably... but I would rather be safe than sorry, especially since a box is about $50.
I picked up 150 rds. of new .180 Rangers. Now I will grab my caliper and for Chuckles and Grins I'll measure and record all my current duty carry rounds to see where they are today, and sample the new ones as a comparison. Back later with the info for anyone who is interested. Thanks for all the input everyone! It is appreciated.
