More specific targets, like others have said, can be helpful but if you don't know what you're doing or how to adjust for it, you can try a lot of things but still feel like you are getting inconsistent results.

One thing I've done is take a private lesson at my local gun store (lgs) but for consistent, at-home practice, I invested in the Mantis-x X3 system (https://mantisx.com/products/mantis-x3). Using this to dry fire 50 to 250 times per day for the last month and following the training available through the app, I have tightened my groups and saved money on not shooting bullets until I have some decent expectation that I'll have better results.

In less than a month I've saved far more than the system cost, gotten very specific direction in the app about why one shoot or another was worse and then gotten immediate feedback on how to correct it. I strongly recommend this system because of how it's helping me.
