If you afford it. Keep that gun. You seem to be shooting it well.
When you get into a slump one "solution" is get a "better" gun. Highly unlikely it will make much of a difference - but you WILL try to buy a better score.
Nothing wrong with a "better" gun if you can learn to shoot it - just keep "old reliable".
Take s few lessons (the VERY best investment you can make) and have fun.
I have been shooting for one year and have met some great people and had a wonderful time learning to shoot better. I remember my first 25 and 50 (74x75 Saturday). Your milestones will be a pleasant memory you will carry with you.
Also, start shooting ATA. You will improve faster under a bit of pressure.
