Well made, simple to use and assemble. great price - CAA Micro Conversion Kit Springfield Armory 9mm/.357 SIG

The conversion kit came exactly as described. The pistol goes in and locks up smoothly everytime. Using it on a xd9 5" tactical and so far the gun has been sighted in at 30 yards. After sighting in I was able to start hitting clay pigeons consistently at this distance, even hitting the halves of what were left after the first round. I haven't tried any further but I do intend to test the limits up to 100yrds. I currently have 150rds through the conversion with no malfunctions. I have noticed the fire rate of the pistol decreased a bit, meaning I cannot let off on the trigger as fast I usually can with the pistol alone. It's not a dramatic change but I'm sure doing a little research on a heavier or lighter recoil spring would solve this.
