I think in Texas your pistol has to be carried OWB not IWB. I believe you have to have a CCW license in Texas to carry IWB.
OWB no license is required.
permitless public carry
In 2021, Texas enacted dangerous ‘permitless carry’ legislation that, effective September 1, 2021, generally authorizes people to carry concealed or holstered handguns in most public spaces without any license, safety training, or background check required, as long as they are at least 21 years old and not prohibited from possessing firearms under Texas’s weak
firearm prohibitions law.<a href="

Penal Code § 46.02(a), (a-5), (a-7).">1</a> A narrow but notable exception is that people who have been convicted of any of four specified violent misdemeanors are not authorized to carry handguns in public for five years after the date that they committed that offense, except when on their own property or when they are inside of or directly en route to a motor vehicle or watercraft that they own or control.<a href="
https://giffords.org/lawcenter/state-laws/concealed-carry-in-texas/#footnote_2_16158" title="Those misdemeanors include assault involving bodily injury, ‘terroristic threats,’ “deadly conduct” that places another person in imminent danger of serious bodily injury, and certain disorderly conduct crimes involving illegal discharge of a firearm or illegal display of a firearm in a public place in a manner calculated to alarm. Tex. Penal Code § 46.02(a)(2)(B).">2</a>
Prior to this law’s passage, Texas law required people to complete a basic safety training course and pass a background check in order to obtain a handgun license from the Texas Department of Public Safety, which authorized them to carry concealed handguns in most public places. Texas law still authorizes people to apply for and obtain these licenses (see below for more information about the licensing process), which may be required, for instance, for people to legally carry handguns in public in certain locations in Texas or when visiting
other states.
Certain location restrictions apply, however, that generally restrict people from carrying handguns in certain types of public locations, including
K-12 schools and certain colleges and universities.<a href="
https://giffords.org/lawcenter/state-laws/concealed-carry-in-texas/#footnote_3_16158" title="See, e.g., Tex. Penal Code § 46.03.">3</a> In some cases, like K-12 schools, firearms are generally prohibited regardless of whether a person has a handgun carry license; in other cases, like most public areas on public college and university campuses, people with a valid handgun carry license may generally carry concealed or holstered handguns, but people without these licenses may not.
