paintball pistol

I went out with just a single PT Extreme on three different occasions.

The first time was in very thick cover and I eliminated several people with single shots and lasted the entire game.  (This pistol was great in the stuff we were playing in; you couldn't see more than 20' in any direction and I got one of the eliminations specifically because my opponents barrel hooked on a vine when he saw me first.)

The second time I lasted the entire game and got one elimination in a face-to-face firefight.  (Popping out and trying to make my ammo last by carefully aiming my shots from 60' away while he painted my cover with the contents of his entire hopper was not fun.  It was challenging, but not fun.)

The third time I was doing okay until a little kid caught me while I was reloading.  He chased me around a large patch of brush while I continued to try to reload and finally shot me on about the sixth lap.  (I imagine it looked pretty amusing to the other players;  I'm an adult and this kid was maybe 10 or 11 tops.) 

I was kind of annoyed about it at the time, but it was the kids first game and I was his first elimination.  Anyway, now I chuckle about it whenever I think about it.

To answer part of the question I forgot to cover in my first post.  Lord Caliber asked about harness's for the pistols.  At one time I had two PTs because I picked one up in trade.  Since I always tinker with stuff I have a very large scrap/excess part pile of paintball equipment.  I had three separate holsters  (One paintball, two for firearms).  I played with several configurations but my favorite was having a tactical holster on my right thigh and a cross-draw holster low on my left side.  Since I'm right-handed I could easily get to either PT with my dominant hand.  Also in a pinch I could turn my wrist and get to the one in the shoulder holster left handed.  Not that I would ever want to shoot lefthanded; if it wasn't for gravity my left-handed shots would miss the ground.  I never used this set up during a game, I traded off one the PTs and one of the holsters for something else paintball related.

The new Ariakon ACP is pretty nice too.  I picked one up and like it quite a bit.  Much lighter than my Zeus G1 and gets about 24 shots to a 12 gram while my Zeus got about 15-18. 

As for going twin pistol it can be done well and not everyone gets lit up.  A gentleman here in So Cal is known for running twin pistol and gets about 5-6 elminations per game.  He moves a lot, can tuck in SUPER tight, and has this little move where he exposes almost NOTHING when he fires.  I mean you see the side of his mask and a hand holding the pistol...that's it.  He's good...but it took time to do that.  If your friend has the patience to learn then go for it but if he doesn't then yes, he is better off going with a more traditional marker.
