Air Javelin Pro - New to PCP - Newbie Questions

Hi Folks - I am new to the whole airgun arena. That said, I just bought the Air Javelin Pro to try it out. My biggest question so far is about filling it. I have done a ton of internet searches and tried to read/watch all the info I can. I know there are multiple options for filling these things ranging from buying a tank - to getting it filled at a paintball place - to using handpump. I am leaning towards using the handpump initially due to price and - to be honest - to make sure I like using these before I invest any more money in airguns/airbows.

So my biggest question is can I use the hand pump? I know the technical answer is yes, but I thought I remembered seeing a video that said you needed to use compressed air on the first fill to seat the o-ring. The manual doesn't say anything about this and I wanted to make sure before I tried it.

Secondly, does anyone have a specific model of handpump they recommend? Thanks!
 
Thanks for all of the replies everyone! Very informative and I appreciate. Since I don't intend (at least now) to use this often, and it is my first air - anything - I think I'll start with the hand pump. I'm not a small guy and while I know it will suck to pump thatthing up to 4500 psi (or close), as long as I don't run it empty - it shouldn't be bad to refill. I did have one additional question about handpumping. Most say they have water/oil filters. Are they effective? I definitely don't want to ruin the air bow because of corrosion, etc. Thanks again!

You are right about the fact that if you refill after 10-20 isn't thet bad at all.

handpumps actually send less moisture then air compressors,....one of those inline filters is really all you want to get if any.
