S-B Ammo Seller and Bellot?
I have the Browning Pro-40 which is a cousin to your gun. i love mine. It's 100% reliable no matter what I feed it and it is spot on as to accuracy. I'm sure you'll love shooting yours for a long time to come.
Only thing I can advice to aid in your shooting is practice and a lot of it. Get to know your gun, relax, and have fun. The more you shoot your gun the better you will know all about where the trigger breaks and now to keep your grip straight etc. A range might help you in that if there's a range master or instructor around you might pick up some tips on grip and stance.
Good luck and happy shooting!!
