I don't own one, but I've shot one and liked it. I thought the weird pinky rest cover thing that comes with the factory 10-rd magazine would bug me, but it actually felt just fine. Recoil was very manageable. You could use your 21 mags in the 30, which is definitely a plus.
Not sure where you are in north Georgia, but the Bullseye gun range in Lawrenceville has one for rent if you want to try it out.
