Bersa Thunder 45 Mag, 7rd, Matte Black

What can you say about a proprietary magazine? It fits into the handle of the gun, and it works okay. Yeah, I know it''s a 45, but couldn''t we figure some way to cram a few more rounds into this thing? A lot of us Bersa owners are poor shots, and we might need every round we could bring to bear in an emergency situation.
