New to me P380 that I bought used did not look like it had been shot much, so I did the recommended (on here) protocol. All of it, including filing down a magazine follower that would catch.
My first time shooting over the weekend it ran flawlessly with the PMC full metal jacket, Hornady Critical Defense, and Lehigh Extreme Defender 68 grain (the Lehigh is the same bullet as the Underwood Extreme Defender, but Wilson Combat bought the company). The Extreme Defender will be my choice for carry after watching gel tests on Youtube.
Thanks to all who did the the work and posts on this forum about preparing a Kahr pistol to shoot well!
