cci/speer 115gn. 1glock mag 33 rnd then 3/33 kci and a 50 rnd from kci. glock mag was more $ but also ran perfectly. as did the 50 mag from kci.. the other 3/33 were randomly problematic and numbered for the test. they all failed more than once, but in almost 500 and 10 i can learn to live with that! Thanks to brother @MikedaddyH for his insights! shoot this all day ! I did it in less than 2 hours and other pistols! link to ammoπ
