The S&W Shield EZ is a hot seller, very popular with ladies and older people who have trouble racking the slide on a regular semi-auto. Not only in stock but they have 233 available. I have never seen any firearm from these guys with that many available.
Things are heading the right way for gun buyers. With California's "assault weapons" ban going to the 9th and then the SCOTUS there might be a window in July when Cali residents can get AR-15s so that should really run demand up for a short time.
Anyway, maybe bide your time as prices seem to be dropping fairly fast but when things level out, don't wait. You might not get a second chance.
