sks;
Thanks for inquiring about Sig-Sauer firearms.
The stamped, or sheet metal slide's are mainly
found on firearms coming out of Germany; and the
stainless milled slides orginate out of the SigArms plant located in Exeter, New Hampshire.
Really, there is nothing wrong with either concept; just a matter of which you prefer. As
I mentioned, the stamped or sheet metal slide's
on Sig's seem to make an arguement for better
balance; ie: P220, P225, P226, P228, etc. On the
other hand, some people suggest the stainless
slides found on the P226 (.40S&W/.357Sig) and
on the P229 (9m/m, .40S&W, .357Sig) makes the
firearm last longer. It is true, that the
stainless slide's will tolerate more natural
abuse; in particular in caliber's .40S&W and
.357 Sig. But, for practical purpose's of CCW
and home defense as well as general shooting;
I prefer the .45 caliber P220 and the P228 9m/m.
All said and done, if I could only afford one
Sig I probably would choose the P228 9m/m due to
the availability of 9m/m ammunition virtually
world-wide; even in some third world countries,
maybe even Afaganistan?

Footnote: Before the Berlin wall came down all
Sig-Sauer handguns were stamped "West Germany"
or W. Germany. Since then, firearms coming from
Germany are simply stamped Germany. All carry
the German proof mark's; that will identify
the year of manufacture, as well as what proof
house did the proofing.
