SIG 225
The SIG P225
is a more compact version of the SIG P220 chambered in 9x19mm with an eight-round single stack magazine. It is basically a single-stack SIG P228 but with some cosmetic differences. The P225 is the cheapest SIG available, although it is only produced in Europe today. Suplus P225s or P6s can still be found for only a few hundred dollars, although most of the surplus has dried up over the past few years.
