...there are places to get pellets that these guys know other than Pyramid...I can't remember them...

...Krale often has stuff because people don't want to pay shipping...

For pellets, always try Trenier Outdoors. He's also an FX dealer I think he may just have received a couple of Saber Tactical Crown stocks.. Get them while they last.
 
Excellent choice. You'll be happy. I'm still waiting for my Impact in .22, but with a 700mm barrel. The reviews of the Compact say it's incredibly accurate for such a short gun.

Who did you get it from and was it in stock?

Oh, and you might want to get some pellets on order. PA took about 2 weeks to get my last order to me. Not bad, but they were out of stock when I ordered. I think most folks are shooting the 18.3's but you might try the 15.89 JSB's when you get the gun. Never know which will shoot most accurate.
