If the quality of the internals are close between the SW and Spartan, which would have the better slide to frame fit and serve best as a base model for future upgrades. Are the SW/STI slides and frames casted or forged? DO either of these actually serve better than say a less expensive SA mil spec as a base for future upgrades?
