Two Letters Re: Handgun Caliber Selection–Advice on .357 SIG and .40 S&W?
Jim, The .40 S&W is proving to be an effective caliber in law enforcement usage, thus its continued popularity in that venue. It is becoming commonplace everywhere, and finding ammo at decent pricing is not an issue. Further, reloading for this caliber is as simple as any straight walled pistol cartridge. .357 SIG is somewhat of a different animal. Some law enforcement agencies have adopted it, but it hasn’t seen widespread adoption like the .40 S&W has. Supposedly at least one agency adopted it because it was more effective at penetrating cars, but it didn’t seem to do any better/worse …
