I have a stainless Interarms PPK I bought back in the mid-1990s specifically
for concealed carry. It gets hot and humid in Texas in the summer, and
stainless is almost required for ccw. I would guestimate I have about
3000 rounds through the gun, and I don't remember a single failure to
feed or eject. The gun was fairly tight when I bought it (new) but it
slicked up nicely after just a few hundred rounds, and it shoots 2 to 3 inch
groups, about 2 inches high, at 15 yards. That is with Winchester Silvertips
and with Federal HydraShoks.
It is a very nice small gun, completely suitable for concealed carry, and even
though I have newer and larger caliber "CCW" pistols, the Interarms PPK
still finds its way onto my belt once or twice a week, especially in the summer
when tee shirts and shorts may be the "uniform of the day".
