At least 100 rounds of .40S&W JHP, a 20 round MecGar mag for my Beretta 92fs, and a few more Ruger factory 20 round magazines for my Mini-30.
Oh and a couple more BX-25 Ruger 10/22 mags if they go back down to $30 instead of being $99 if you can even find them right now.
The Tavor is a slick weapon! Made by IWI which manufactures my IWI/Magnum Research Baby Eagle II .40S&W I just purchased. I spent over a week hunting one down.
