Frequently Asked Questions

What is the RD SFS system and how does it work on a 1911?

The RD SFS (Safety Fast System) allows a 1911 pistol to be carried 'cocked and locked' with the hammer appearing uncocked. You manually push the hammer forward, and the safety automatically engages. Pushing the safety down releases the hammer to fly back to the cocked position.

What modifications were made to this Colt Defender 45acp?

This Colt Defender features a Hollison 407K red dot sight, with its mount machined directly into the slide. It also incorporates the RD SFS system, which modifies the hammer and safety mechanism for a unique carry method.

Can the RD SFS system be used on both Series 70 and Series 80 1911 pistols?

Yes, the RD SFS system is available for both Series 70 and Series 80 1911 platforms. While Series 80 pistols can be converted to Series 70, the SFS kit can be installed while retaining the original Series 80 safeties.

What are the benefits of the RD SFS system for carrying a 1911?

The primary benefit is the ability to carry a 1911 'cocked and locked' without the visual cue of a cocked hammer. This can appeal to individuals who prefer this carry method but are concerned about the appearance or perceived risk of a visibly cocked firearm.
