What are your experiences using the Pearce Magazine Extension (PGG45P2) on a Glock 21 13 round factory mag?

Has it affected reliability of operation? Any evidence the extension will require a stronger spring? Do the rounds rattle around in the mag when loaded with 15?

I've used the +1 and +2 with no problems of any kind. They are nice additions to any Glock pistol. You don't know they are there.

I have used them both in a Glock 21 and 27 and they worked perfectly. Unfortunately I don't like Glocks and sold both with the Pearce extenders or I'd give them to you free.
