Is there a difference between a Glock 22 magazine and a Glock 35 magazine? The reason I ask is I was ordering a few items off Midway USA and wanted an extra magazine for my G22. They have Glock 22 magazines listed as "Glock 22, 35 40 S&W". It has the same product number and name as their Glock 35 magazine. So just wondering if they are exactly the same.
