Djmyers, You leave the air in the gun, even if storing it for long periods to keep dirt out.
On the Talon SS, the tank is empty when you get it. Filling it with a hand pump will take a long time. After it full, it takes about ten minutes to refill it, maybe less. I never tried to break any World Class Records at filling the Talon.
However, time is not the question here. Heath is. If you’re a young man of average size a hand pump would work fine for you. For a old goat like me, it is a real work out. I got to the point that I hardly ever shot the Talon because of pumping air back into it.
I just bought my second PCP, but I also bought a air compressor to fill it with. I live out in the middle of no where, about 10 miles pass the boonies. Filling a scuba tank would cost to much in time and money for me.
However, that is how most guys charge their guns. It’s something you have to look into your self.
Now, look around all the airgun web sites. How many fellows you see filling there guns with hand pumps? Very few. Why? It’s easier using a tank. And for those that shoot in matches, having swore shaky arms and heart rates so fast that they can’t hold their guns on target is just not what they want.
Bottom line, a hand pump will get you by until you can get the cash together for a tank set up.
