I examined a pair of EZs in .30SC about 2 weeks ago. One had a very heavy, gritty trigger; the other had a lighter, grittier trigger. Neither were what I'd recommend for someone with limited hand strength, which I understand to be the target market for the EZ.
The shop had already sold the only standard .30 Shield they received, so I can't comment on that. They had one 20 round box of ammo for $32.95.
