Optics planet is great, but this shoulder holster is not. bianchi customer server is horrid.i - Bianchi X16 Agent Unlined Shoulder System Holder

I like shoulder holsters, there are many months in Texas where it is just not usable, too hot to wear a jacket to cover.
But I still like shoulder holsters. Just bought this one for a Glock 21 and another brand for a Glock 19X. Both hold the handguns fine, but very tight. The magazine holster on this Bianchi is way too small. I can't even fit a Glock magazine for a 9mm full frame in this mag holster. It might fit a mid-size frame Glock 9mm. Impossible to snap the magazine holster with a .45 full frame Glock magazine. Guessing that the width would stretch with use, but the length or snap cover would never stretch 1/2 inch. The distance between the snaps with a Glock 21 magazine is almost a 1/2 inch gap. No way the leather would stretch that much. I contacted Bianchi customer service and offered to buy the next size up magazine holster and the cust serv person basically told me I was an idiot. What I had was the right size and maybe their leather drying process caused it to be too small. No option to resolve this except to return to the retailer.
Optics Planet is a great retailer. I have bought many items and every other item is superb.
I have several Bianchi belt holsters. Love them all. But this shoulder holster will be the last Bianchi I will ever buy. Good Customer Service is hard to find anywhere since Covid. So my expectations are lower. But when a company has customer service as poor as Bianchi I will never buy from them again.
