That is so good to hear. Every girl/woman I have ever introduced to the sport of shooting has really enjoyed it. My Shadow also has the lighter springs that you installed in your SP-01. Remember that the trigger and all-over functionality of all of the SP-01's improves the more you shoot it. I had some FTF issues at first, nothing I was worried about and only with the Remington UMC (green box) and Hydroshock ammo. Winchester white box, S&B, Magtech and American Eagle all worked perfectly. The Federal LE Tactical HST +P Hollow Point ammo in both 124 and 147 grain has run perfectly and I can recommend it as a good self defense round although there are plenty of others that work very well. My Shadow really smoothed out after 1000 rounds and is now running 100%.
I'm looking forward to reading your range report next week.
