10mm 1911 mags which ones?

My Kimber mags work great

Well I bought metalform mags and they fell out on the first round. Then I tried a Chip McCormik 45 mag and it worked perfect. Fed as fast as I pulled the trigger and never fell out.
But after the first mag fell out I ordered a Les Bauer mag release to see if it would help.
Golden. Every one of them stay put now.
I think it was 20 bucks at midway.
