Ok..looks like there is a SC model that was introduced last year. Found some good info on Wikipedia:
"The Caracal SC has been introduced at the IDEX 2009 exhibition on 22 February 2009. The SC model has a reduced length, height and is technically somewhat different compared to the other Caracal pistols. The manufacturer markets the SC model as a primary weapon for government professionals who must conceal a handgun for job related situations, or as a secondary back up pistol.[1] According to Caracal's managing director Hamad Khalifa Al Neyadiof, the new SC sub-compact model has fewer screws giving a smooth surface, allowing for a more efficient assembly and a better quality build. The SC model can also use the larger detachable box magazines of the C and F models, giving a magazine capacity of up to 18 rounds of 9 mm ammunition.[11] According to Jane's the SC model has a separate safety switch located beneath the trigger guard, rather than on the trigger itself. A special grip adapter that has been developed for the Caracal SC has to be used for using the larger magazines from other 9 mm Caracal weapons. The SC model also has a solid synthetic striker, resulting in reduced manufacturing costs and a very smooth action. The synthetic unit will be introduced to the F and C series later this year.[12] The SC magazines are offered with a standard flat bottom or a slightly developed magazine with a finger rest for extra grip.[1]"
Sounds like there is some sort of external safety switch underneath the trigger guard on the SC variant. I don't know if this is a passive or active type safety. It wouldn't make much sense to put a manual safety on a sub-compact model that is intended for concealed carry. At least I don't like manual safeties on my carry weapons...
The "synthetic striker" also sounds bad to me. I don't know how a plastic striker/firing pin is supposed to hold up. It mentions that the synthetic striker reduces manufaturing cost. Cutting corners is never a good thing IMO. I guess we'll see.
