your p238 isn't going to have a better grouping than the taurus, but that's because you traded a full size gun for a micro mouse gun. the sig is a great gun for carry. congrats on the upgrade.
Favorite range gun for the money - CZ 75B or STI Spartan V 9mm
Go-to carry setup - Walther PPS or PPQ in FIST kydex holster 1AK
Favorite .22LR - Browning Buckmark
