If the mags are .40S&W factory Glock mags and lock in place properly they should also work properly. I have Glock mags & Glock pistols that span a roughly 20 year period of manufacture and have had no issues with old mags not working in new guns or new mags not working in old guns.
The only intra-caliber incompatibility issue I'm aware of would actually preclude the magazines from locking in place.
