Was it a good deal? Can it be modded to improve performance?

That's a pretty good deal, but as the gun is a PR, not much can be done. I would only use it as a sidearm, especially considering how fast it runs through water on the largest nozzle.

Be sure to pre-pressurize it with air before shooting water, and I would guess that it should perform quite well. It's a bit larger than the XP270 but supposedly performs considerably better despite the slightly smaller firing chamber. (This is likely due to having a Max-D trigger.) Of course, for it's size, it ought to perform much better, but it is what it is, and for $4, I'd take one without question.

For its size, it's more of a secondary than a sidearm, which is more or less the same thing depending on how you handle multiple blasters. If I had one, I'd strap it up and load it light enough so that it doesn't encumber too much. Of course, I could do the same for a Flash Flood or Tiger Shark and that'd probably be a better idea anyways.
