hi-cut (or at least highER cut than a regular SA1911!) checkered front strap, SA or similar mag well, ed brown or EXACT COPY grip safety, full 5" size, night sights or target sights or both. I don't like SA's cause of their low cut front strap, ambi safety okay but not a requirement. reliability comes before accuracy for this purchse... so more combat minded gun than target. looking to cap out ata grand.
