I bought this for my spyder but accidentally got a Pirahna one. And contrary to common beliefs, It DOESN'T FIT! The mout screws were about a 1/4" off. The trigger got loose and had a bit of slack. One of the buttons on the back was missing. It kinda sucks cuz you have to take off 3 screws to change the battery. It has comfortable hogue grips though! Nice! Nice LCD screen, lighted. Lots of modes. Great rate of fire! non removable trigger guard..
Conclusion:
It's great for the price. 2nd best aftermarket frame you can buy for a gun! RIght behind the mako. If you dont have an E-Frame and are upgrading to one buy either a mako or a booyah!
