I have a Sig P229 in .40 S&W...a really nice shooter. And, the one constant theme on these gun threads is that if you are going to be proficient with any weapon, you have to practice...a lot. I have attended two CCW classes and shoot every weekend a minimum of 100-rounds...and I suspect many posters will tell you that isn’t a lot, even for a non law enforcement private citizen. You owe it to yourself and those around you to be very familiar with you weapon. If you can not dedicate the time or $$ to buy ammo, don’t buy a pistol.
