Back when I feared Clinton would win the 2016 election, I bought up 1000 rounds of Speer Gold Dot 124 grain 9mm Parabellum +P. I never shot any of it, just socked it away in ammo cans. Well today I hit the range with the P9 Covert and C R A P the stuff causes occasional stovepipes!
These cannot be cleared with "tap, rack, assess" drills but instead require "lock, rip, work" drills. Ugh!
Also, like with Sellier & Bellot 124 grain, the bullets seem too long and a "sling shot" of the slide with the weak hand causes the top round to dive and not chamber. Both chamber fine using the slide release though.
Both tend to go slightly left but that may be my poor shooting.
For years I had excellent accuracy, point-of-aim hits, and reliability from PMC Starfire 124 grain +P but I saw a video where the round failed to expand in ballistic gel.
When my K9 comes in I'll see if this stuff does any better in it.
