I don't really know where to start, I'll go over what I believe are shortcomings in my review.
Let me start out by stating that I don't own a Pirhana. My experience with these guns is purely from teching at my local field. From what I've seen, I would not recommend this gun for most players. This review is based on multiple STOCK Pirhana GTI's. I have not tested the marker with any upgrades.
First of all, the GTI is still just a sear-tripper. That means that it inherits all of the kick from its mechanical counterparts. In all blowbacks, you have a huge reciprocating mass kicking around inside. The Pirhanas are no different. This is the same as any Spyder, and any other blowback.
The main disadvantage that should be apparent right away is that there almost isn't a need for the electronics. This marker CANNOT shoot fast in stock configuration. I have never come across a trigger like the GTI's. It is, at once, extremely sensitive, yet impossible to fire quickly. When firing, I felt very disconnected from the gun. I believe it is a combination of slop in the trigger after the pull and a capped electronics board that limit the gun to a very low speed. I'm sure there are ways to bypass this, but every stock Kingman E-marker I have seen is easier to shoot than the GTI. I found that I could shoot faster with a mechanical trigger. This, of course, takes more effort. I don't understand why the Pirhanas are so slow, when the trigger is reasonably sensitive.
Quality control is somewhat of an issue, from what I've seen. I had one GTI come in leaking from just about every hole in the body. After half an hour trying to teflon or reseat every seal and screw, I looked down at that valve. PMI had installed the valve backwards from the factory without ever testing the marker. This meant the cupseal couldn't seat, and it was leaking huge amounts of air. Also, most GTIs have to have their springs cut before I allow players to use them. I find that they are regularly coming from the factory shooting at around 335 when completely turned down.
There are still some redeeming features on the pirhana. The sear-dropping switch is great for reassembly. (Field stripping is slightly more difficult than a Kingman, simply because the hammer must be pulled completely out to remove the mainspring.) The gun is very lightweight, and points well. The milling and annodizing is well-done, and the price is reasonable.
I would recommend buying a mechanical Pirhana instead, unless you know enough to do a trigger job and can deal with possible mechanical defects from the factory. The rate of fire is not sufficient to justify having a battery.
