Disappointed with my Condor

Well I pulled the trigger on a .25 condor, I got it from airgun depot with a hill pump and a free CO2 adapter plus a CO2 tank. When I pulled the rifle out of the box the grip was loose and easily twist-able. I tightened the nut in the grip cavity and somewhat fixed the problem, however the grip still has a little play. Its almost like the grip doesn’t sit high enough on the frame and lacks lateral support and I cant believe the grip is held in with a single screw. After all that, I screwed in the CO2 tank and nothing! The pins won’t touch that engage the valve on the CO2 bottle. I socked this tank onto the adapter and still couldn’t get the value to open. I cut up a penny and placed it in the adapter so the pins could reach but I couldn’t get the O-ring to engage and bled out half my tank. It seems the pin on the adapter isn’t long enough to open the valve. I am asking you guys for solutions. I am contacting tony to speak about a wokgard 15 mk2 for the grip. As for the CO2 adapter I will be contacting Airgun depot tomorrow asking for an exchange. I’m finishing up my senior year in college right now and for me to drop 1100 on an air rifle was a huge commitment, meanwhile I have my dad telling me I should of gotten and M-rod every chance he gets, so lets hope I made the right investment.
