I know dealers were out of the Wildcat Compact .25 for a while but they are starting to trickle in, I got mine from PA this week, comes standard with the AMP regulator and the X liner, after shooting a few hundred pellets I shot over chronograph and the 25.4's are just above 890 FPS and the 34 gr MK 2 are hovering around 798-803 consistently.Did a shot string and got 33 good full power shots before it fell off the regulator (4 mags). This gun is impressive to say the least ! I had several FPS numbers that were a duplicate and most only a few FPS from min to max.for the first three mags. And it gets even better, at fifty yards with either pellet groups are dime sized. Shot at 100 yards and groups don't open up very much from 50 yard groups. I'm totally impressed with this little pup !
