How about the .357 SIG as a chambering?

How does it compare to other cartridges, such as 9mm Para, .40 S&W etc?

Does it qualify as a major IPSC round as does the .38 Super for example? (Note: Remember in Aust calibres over .38 are restricted for many disciplines eg IPSC)

I was told last week however that I should join another range, where for example silhouette comps, guys are using .45 1911 etc.

(Where an argument could be made the additional knockdown power was required to knockdown steel targets, or where the comps were Comnibwealth and Olympic Games comps, exemptions to allow greater calibres were made.)
