Don't listen to this guy. As a matter of fact the double stack single feed magazines are even more reliable since they feed straight into the chamber as opposed to a wider hollowed out chamber/mag combo that's meant to hopefully feed from two angles. The reason the Glock mags are hated by wannabe smg fags is because they're harder to reload as opposed to pushing straight down into them. That's it. Their baby hands cant load Glock mags. That and since they tend to be delusional "purists" (with semi auto versions of their "smg", top kek), they despise the "ugly" Glock mag.
No one runs PCCs harder and longer than people who compete in USPSA, and I can guaranfuckingtee you that 90% of us are using Glock mags. No one wants a malfunction especially in the PCC division where everyone's extremely fast (because of how easy they are to shoot). A single malfunction will kill your score. So Glock Mags are extemely good to go on a PCC. Cheaper, more reliable, durable, and you can change out the baseplates on them to find exactly what it is you want length and capacity wise.
Also, out of those options go GHM9. You won't find a better built PCC for the money. Swiss quality has always been amazing. My B&T SPC9 shits all over my other PCCs in regard to fit, finish, and reliability. 20k rounds, not a single parts change, two cleanings, running like a champ.
