I have an IMI Uzi Baby Eagle (Jericho) -- COMPACT.

The grip and barrel/slide are shorter than the full size gun.

I'm wondering if the high capacity mags fit in this pistol? I don't care of they extend beyond the butt. I just wonder if they'll function.

The "compact" mags are about 12 rd. The "high cap" are 15 or 17 rd. And I can find them in stock at Numrich.
