Been trying for weeks to get an answer at Glockstore about their T1083 Heavy Extended Aluminum Magazine Base...they still aren't answering phone, email, or their send us a message dealie. Finally occured to me the answer to the question might be here on the GT forum with all the experts. Just want to know before I buy how they attach to the magazine (G26 gen 4)? Do they replace the existing magazine base plate? Do they attach to the existing magazine base plate somehow? Lenny won't answer the phone to answer the question so maybe someone else can for him. And, depending on the answer I may not need them after all and don't need to fret about being ignored any more. I want red ones to help trick out the G26 and to make it more obvious which magazines go to the G26. Thanks for any wisdom.
