I normally shoot from point blank to 20 yards.
Most targets between 5 and 10 yards. I have been shooting handguns a very long time, and I do not normally carry anything smaller than a compact pistol. Semi Auto: G23, G38, and my 1911 Colt some. Revolvers: 2" K Frame S&W 64, 3" K Frame S&W 66 being my normal carry rotation at the moment.
My suggestion for you, would be to keep expanding your horizons during your training/practice.
No mention of what you are shooting. This can have a big impact on training distance. Little toy size hideout guns are normally very hard to shoot well.
Are you shooting on a Range? Indoor or Outdoor?
More information on what you are shooting would help with responses. Their is a huge difference between what can be done with a subcompact pocket pistol, and a Glock 19 as far as engagement range.
EDIT: OK looks like you are shooting a SIG 938 and live in South Florida, and have been shooting for only about a year. That gives us something to work with.
The 3" barrel Sig 938 should be a pretty good pistol for a small compact carry gun. It is a single action with a thumb safety. So far that tells me that you should have a tolerable trigger, and enough sight radius to shoot it reasonably well with practice and training.
I would work on accuracy with it first. Keep moving back from 10 feet to 30 feet as you keep getting better with it.
Once your accuracy is at an acceptable level, start your drill with your pistol concealed the way you would normally carry it. This will probably require an outdoor range to practice at. Now try and wear your Sig 938 out, one round at a time. Shoot it as much as you can, making every shot count. Your LE shooting buddy should be able to keep you pointed in the right direction.
