It is an Offical product
Grip frame was better "Fit" for small hands than Booh-Yaa
Not a well made as centerflag
Unknown who really makes it KINGMAN or another "fly by night" like Booh-Yahh
Unknown warranty /life
Sear wore badly after less than 10,000 shots
Great if I can get service. Will post after the outcome.
Sent it in, but last thing I sent In (EM-1) took 6 months to get back.
Using Centerflag right now. More people have the Centerflag it seems, but they have been out longer. I know of Ten Centerflag users, only 3 had to sent back.
Some had over 100, 000 rounds on them. (50 cases over two years)
Booh-Yahh Grip cost me $25 round trip, $15 was a charged repair- MAKO
took over and is standing behind the BooH-Yahh items with great service.
Centerflag seems to have a higher Quality, and the Repair was free.
Centerflag also had the best service & fastest tunaround (East Coast!)

This works very good. I have been able to get the gun to Cycle at 13 rps with no problems but can only fire about 10 -12 balls per second. The adjustable trigger can be set for a VERY short pull, almost a touch will fire the gun.
They say that it will work with all Spyders, but the Striker (Striker Bolt) included is for the Compact Body style. I am not sure of they have one for the Original Body style or not. It took me a day worth of Modifying the Striker to get it to work correct.
After the work was done to the Striker I love it. If this worked out of the Box I would give it a better rating. I am contacting Kingmann about the Striker issue and if they don't have anything for the Original Body and want to do the same and I will give instructions on what I did to make it work.
