That would be a Sigma. S&W doesn't sell *exactly* the same model, but does still make the SW40VE which is a slightly improved version of the same gun in .40S&W.
You should just be able to get parts from S&W without any problem. Heck, they still sell magazines for the defunct 10xx pistols, so I'm sure you can get Smegma... er I mean Sigma parts.
BTW, .40S&W and .357 Sig magazines are usually exactly the same except for being stamped ".357 Sig" instead of ".40S&W." You probably won't find any hicaps marked ".357 Sig," but there are .40S&W hicaps out there for the Sigma that should work.
