CGW Double Action Ultra-Lite Kits
Frequently Asked Question on the UL-DA Double Action Kit
Is this kit reliable with all types of primers and ammo? CGW's Ultra-Lite Competition kit can only be used reliably with Federal SP primers when using the very light HS-8500 (8.5#) hammer spring. It will not work with any other primer consistently. HS-12000 will reliably ignite practically any primer
Is this recommended for self-defense use? Only the Ultra-Lite Self-Defense version. The Competition version IS NOT RECOMMENDED for self defense use.
Will this kit make my single action dangerously light? No. Although the SA pull weight is affected, the difference is not as pronounced as you would expect.
What type of pull weights in DA can I expect? With a smoothed action, HS-8500 can deliver a 5 lb pull, or less, HS-12000 can deliver 7.0-7.5 lb pulls. HS-13 in the Ultra-Lite/SD will deliver 8.5-9.0 lb pulls.

Why a CGW firing pin?
CGW uses a "flat" impact face for the hammer. This eliminates peening of the hammer face. CGW firing pins are also longer on both ends. This means more force is transmitted to the primer = better ignition.
The low-lift area for the FP block means even with lower hammer hook geometry, the FP block will clear the FP, virtually eliminating mis-fires.

Ultra-Lite/SD- The ultimate in a light trigger pull and stellar ignition. Designed for self-defense and range shooters. Includes CGW's premium HS-12000 and HS-13 hammer springs, reduced power firing pin plunger spring, and our S-7 tool steel extended firing pins. For use in firing pin block safety CZ's ONLY.
Please NOTE: If you want the benefits of this kit AND a short reset, see the SRS-2 short reset kit.
Ultra-Lite/SD-NFPB - The same as the Ultra-Lite/SD but for the Shadow and 85 series that DO NOT use a firing pin block. Delivers an ultra-reliable yet light weight DA trigger pull.
CGW offers the only engineered drop-in double-action components to transform your CZ's DA pull weight. Stock is a very stiff 16 - 18 pounds. The CGW Ultra-Lite Kits, depending on which version, lowers this to 5.0 - 9.0 pounds. Best of all, the Self-Defense versions retain 100% reliability.
