I'm using the same load (3.0gr of N320, 1.140 OAL) in my SP01 Shadow... Works perfectly with a 10# spring. Consistently @ 130 -131 PF. No tumbling at all!
Just received my SP-01 Shadow Custom on Wednesday with the new Short Reset Trigger. It is awesome! The SA trigger is very light and short... It's perfect!
Thank you to everyone that made this happen. It was a great match at a great facility! We made the trip over from Columbus Ohio and it was worth every minute of travel time. We will be sure and spread the word in Ohio about the good things going on in Sparta!
