I also have a CGW SP01 . I switched out the hammer spring for a 8 1/2 lb spring and it made my double action pull drop from 7 1/2 lb's to 5 1/2 lb's with 100% reliability with Federal primers .
Mine is just a range / IDPA gun but I have over 1000 rounds through it with that light hammer spring and not one fail to fire with the Federal primer . |
