Just shoot the darned thing.
I think you're going to have to shoot it a while before you can make a meaningful assessment of its ability -- most of your first box or two of ammo will be used to just get used to the gun and its trigger pull.
Its a rare shooter who can shoot a new gun to its full potential the first time out. I've got any number of guns that I wasn't able to shoot well, out of the box... but over time seemed to get better and better with them. Don't know why that is, but it seems to be a "psychological thing." After having shot it 4-5 times, now, I'm just getting to where I can shoot my DaeWoo worth a hoot. [Still haven't been able to make my CZ-40B shoot where I think it should, however.]
Start up close. Check that the sights are right, and start shooting. Move the target back, etc.
Shoot a couple of sessions, let the new/novelty wear off, and then get down to the serious assessments. It'll save you a lot of frustration and it won't get you upset with the gun, unnecessarily.
I'll be surprised if you aren't tickled with gun. But don't expect too much the first time out. You'll probably have problems, and it won't be the gun...
