If you don’t already have one, I’d recommend you get a laser that allows elevation and windage adjustments and can be mounted on the frame’s dovetail rail (the barrel, after all, is secured to the frame via bushings and set screws) to guide you in developing the correct hold technique for your Airforce PCP. You don’t need an expensive one—even a Walmart-stocked unit works perfectly. One of the benefits of a rifle-mountable laser is that it can be used as a diagnostic tool, if not as a sighting system. I used to own a Condor and wanted to see the effect of hold pressure, especially lateral pressure, on the rifle’s point of aim. Let me tell you, it didn’t require too much pressure on almost anywhere on the rifle’s frame to see the laser dot move from its original position. Having done that, I was given a headstart and set on the correct path to developing my hold technique for “a rifle”—not just the Condor—and was able to find one to counteract any possible negative pressure that in turn can change the barrel’s aim point.
If you decide to give it a try, once mounted, adjust the laser so that the dot is superimposed on the crosshairs of your scope. As you look through the scope, apply pressure on various parts of the frame to see if the dot moves. Best to conduct the test wherein the dot is at a considerable distance, like 40 yards, to amplify the degree of movement. That should give you an idea of which area(s) to situate your non-firing hand or which type of hold to apply to prevent this problem from getting in the way of accuracy.
