I have both 7 round and a 9 round factory mag. for the .380 thunder, they are the same length but hold different amounts of ammo...

Can the 7 round be modified to hold 9 rounds

The only difference I can see between the 2 mags is that the 9 round mag has an extra hole in the side and the spring seems a little shorter, I guess so the spring can compress more for the extra round and is used in the BT380cc. I use them both in my BT380 and BT380cc without any problems. I am not qualified to recommend or try to modify the mags. Maybe a gunsmith would know.
