Hi Deebee,
It's taken me 9 months from getting my first pistol to where I am now happy(ish). with the way I shoot It does take a while to pick up.
I have got to the point where I can now swap from my co2 to my SSP and my Springers and within 15 shots get "into" each type. Start with a 10m target at 6m if you don't feel confident.
Jonyb is quite right, practice a lot and have fun. (and join the bbs comps)
