So my seal is horrible. But its not with the barrel. The problem lies within the plunger head. I've never fancied putting etape on my plunger heads so I refuse to do that unless totally necessary. Any other ways to improve the seal?

How about silicone or teflon tape both work very good. Silicone tape is nice because it is very silimlar to an o-ring and teflon tape is a tad bit better in my opinion. But nothing beats a fatter o-ring.

Try a neoprene washer sandwich like CS recommends for the LS. Works awesome for me.
If you don't want to go that extreme, just add/replace the O-ring

I had this problem with my DT3 pistol too. I used E-tape and lube, but if you don't want to do that, then I don't know what to tell you. Oh, and splitlip, I don't think you understand that this gun is not an O-ring gun, it's older and uses the rubber plunger head.

I came up with something yesterday (while working on my Secret Shot) that may be exactly what is needed here...
Instead of adding the electrical tape to the outside, which relies on the adhesive of the tape sticking to the normal working surface of the plunger head, I cut a long strip, then cut it in half length-wise. Next, I cut a 1/4" wide section of bike inner tube, then cut it in to one strip. Next I took the plunger head off of the rod, and folded the cupped portion back, out of the way. I then wound the inner tube section around the inside portion the head (more to take up space to reduce the amount of e-tape needed than anything else), and covered it with the long strip of e-tape. I ended up using both halves of the 18 or so inch long strip. Lastly, I folded the cup back in to normal position and reinstalled the head on the rod. Of course a liberal application of silicone grease is required upon re-installation to the tube.
What this gains us is added tension on the working surface of the head from the inside, so we end up with a better seal from the original working surface, and negates the need for the periodic maintenance or replacing the e-tape. I'm pretty happy with it, and plugging the hole in the tube will indeed stop the plunger. Sorry for the lack of pictures. I'll take some when I open up the gun again to try and improve the seal from the tube to the barrel plate.

I'm not quite sure with all the oring suggestions but I think I may try the whole metal and rubber washer thing.
