I have run CZ SP-01 Shadows in USPSA Production division for a year and a half now and here are my thoughts and a comparison to other firearms.
If you have been following my blog you may already know that my primary match gun is a CZ Custom SP-01 Accu-shadow with blue Shooting Sports Innovation Scale grips that I have nicknamed “Blue”, and my dryfire/practice/backup gun is a standard CZ SP-01 Shadow that I did the work to and it has the same SSI Scale grips in red, nicknamed “Red”.
The only changes that I have done to Blue to improve on upon what CZ Custom has done is some additional polishing to the trigger components, but the trigger work from CZ Custom was really good. I switched out the sights to a Dawson front sight and removed the HAJO rear and put in a factory Shadow sight. I also replaced the thumb safeties and slide stop with the RAMI style thin safties and stop as I don’t use the safety in Production division and my thumb sits much higher and doesn’t rest on the safety. I put in a heavier recoil spring, as I noticed some battering to the recoil guide rod with the 11 pound that came with the gun, so it currently runs a 12 pound. Blue currently runs an 11.5 pound mainspring from Cajun Gun Works which is another reason for upping the recoil spring weight. Current double action weight is 5.5 pounds and the single action weight is 2.0 pounds. (more…)
