I can speak to this a bit. I edc a Glock 27.4 with an Alpha Wolf G33 barrel in it. Before that I’ve had oem, & storm lake 33 barrels in my G.4, & my 27.3 before that. Since I only shoot .357 sig. I have tons of 33, & 27 mags, & even 23, & 32 mags I run in my gun. I’ve never had 1 issue in 2 guns & thousands of rounds.
