Replied too soon, missed the question you added. Yeah ammo is odd, but readily available, not cheap though, so do most of your practicing on other guns.
It's like shooting a hot .22lr - no recoil, you can stay on target and keep going without issues. Lead in the air if needed. 17 or 20 rounds depending on mag etc. Ridiculous velocity, over 2,000 fps out of a shortbarrelled pistol.
Light weight, about a pound less than a Glock 17 once both guns are fully loaded. It's tough to cock, my wife can't do it, so it's childproof in a way.
I think I paid $850 for it, bought with LE discount (a family member is a retired cop), I think they're north of $1K now?
