Glock 33 mag with the TF +10 is all you need .... and the TF extension makes for a nice grip if you had to reload.
The key for me is not to load past 36, works flawless so far.
Resale is always a consideration for me when a making a purchase, and JP's hold their value.
and no reason to mod the JP unless you have the time and money, they run perfect stock.
