    Registration Statement on Form S-4

    Filed on July 26, 2021

    File No. 333-258176

Dear Sir or Madam:

On behalf of
FirstSun Capital Bancorp (“FirstSun”), we hereby submit responses to the comments provided
by the Staff of the Division of Corporation Finance (the “Staff”) of the U.S. Securities and Exchange
Commission (the “Commission”) set forth in your letter dated August 2, 2021 (the “Comment
Letter”) with respect to the above-referenced filings (the “Form S-4”).

For your convenience,
we have set forth each comment from the Comment Letter in italics and bold typeface and have included the Company’s response
below it. The numbered paragraphs in this letter correspond to the numbered paragraphs of the Comment Letter.

Form S-4 filed July 26,
2021

Material U.S. Federal
Income Tax Consequences of the Mergers, page 105

 1. We
                                         note you have filed short form tax opinions with your exhibits 8.1 and 8.2. We further
                                         note the first paragraph in this section says that it is the opinion of counsel that
                                         the following discussion summarizes the anticipated material U.S. federal income tax
                                         consequences of the merger. Please revise to identify the specific tax issue that counsel
                                         is opining upon and remove the language that appears to indicate that counsel is opining
                                         upon a summarized discussion. Please refer to Section III.C.2. of Staff Legal Bulletin
                                         No. 19 (CF), available on our website.

Response:
The disclosure set forth in the section entitled “Material U.S. Federal Income Tax Consequences of the Mergers”
has been revised in response to the Staff’s comment. Such disclosure now provides that it is the opinion of Nelson Mullins
Riley & Scarborough LLP, counsel to FirstSun, and Bracewell LLP, counsel to Pioneer Bancshares, Inc. (“Pioneer”),
that the mergers will qualify as a reorganization within the meaning of Section 368(a) of the Internal Revenue Code of 1986,
as amended, for U.S. federal income tax purposes and that accordingly the material U.S. federal income tax consequences of the
mergers generally applicable to U.S. holders of Pioneer common stock who exchange their shares of Pioneer common stock for shares
of FirstSun common stock pursuant to the merger will be those set forth in this section entitled “Material U.S. Federal
Income Tax Consequences of the Mergers.” Exhibit A hereto sets forth the revisions to the disclosure.

Exhibits

 2. Please
                                         refer to Exhibit 8.2. We note the language in the last paragraph that the opinion is
                                         being furnished solely to the company in connection with the filing and is not to be
                                         relied upon for any other purpose without your prior written consent. Limitations on
                                         reliance are not acceptable. Investors are entitled to rely on the opinion. Please revise
                                         accordingly. Refer to Section III.D.1. of Staff Legal Bulletin No. 19.

Response:
In response to the Staff’s comment, the tax opinion of Bracewell LLP, filed as Exhibit 8.2 to the Form S-4, will
be revised and filed with the next amendment to the Form S-4 to delete the first sentence of the last paragraph of the legal opinion.

We
are available to discuss any of our responses with you at your convenience. Should you have any questions or want to discuss these
matters further, please contact me at (404) 322-6153 or Brennan Ryan at (404) 322-6444.

Exhibit
A

MATERIAL
U.S. FEDERAL INCOME TAX CONSEQUENCES OF THE MERGERS

Subject
to the limitations, assumptions and qualifications described herein, in
the opinion of Nelson Mullins Riley & Scarborough LLP, counsel to FirstSun, and
in the opinion of  Bracewell LLP, counsel to Pioneer,
theThe following discussion
summarizes the anticipated material U.S. federal income tax consequences of the mergers generally applicable to U.S. holders (as
defined below) of Pioneer common stock who exchange their shares of Pioneer common stock for shares of FirstSun common stock pursuant
to the merger. The opinions of tax counsel for each of FirstSun and Pioneer is filed as Exhibit
8.1 and Exhibit 8.2, respectively, to the registration statement on Form S-4 of which this proxy statement/prospectus is a part.
This summary is based upon the Internal Revenue Code of 1986, as amended, the “Code,” Treasury regulations
promulgated thereunder, judicial authorities, published positions of the Internal Revenue Service, the “IRS,” and
other applicable authorities, all as in effect on the date of this discussion and all of which are subject to change (possibly
with retroactive effect) and differing interpretations.

The following
discussion applies only to U.S. holders of Pioneer common stock who hold such stock as a capital asset within the meaning of Section 1221
of the Code (generally, property held for investment). Further, the discussion does not purport to consider all aspects of U.S.
federal income taxation that might be relevant to holders in light of their particular circumstances and does not apply to holders
subject to special treatment under the U.S. federal income tax laws (such as, for example, dealers or brokers in securities, commodities
or foreign currencies; traders in securities that elect to apply a mark-to-market method of accounting; banks and certain other
financial institutions; insurance companies; mutual funds; tax-exempt organizations; holders subject to the alternative minimum
tax provisions of the Code; persons who are required to recognize income or gain with respect to the merger no later than such
income or gain is required to be reported on an applicable financial statement under Section 451(b) of the Code; partnerships,
S corporations or other pass-through entities (or investors therein); regulated investment companies; real estate investment trusts;
former citizens or residents of the United States; U.S. expatriates; U.S. holders whose functional currency is not the U.S. dollar;
holders who hold shares of Pioneer common stock as part of a hedge, straddle, constructive sale or conversion transaction or other
integrated investment; U.S. holders who acquired Pioneer common stock pursuant to the exercise of employee stock options, through
a tax qualified retirement plan or otherwise as compensation; or holders who exercise dissenters’ rights).

In addition,
the discussion does not address any tax consequences arising under any state, local or foreign tax, or under any U.S. federal
laws other than those pertaining to income tax, nor does it address any tax consequences arising under the unearned income Medicare
contribution tax pursuant to the Health Care and Education Reconciliation Act of 2010, or any withholding considerations under
the Foreign Account Tax Compliance Act of 2010 (including the U.S. Treasury Regulations issued thereunder and intergovernmental
agreements entered into pursuant thereto or in connection therewith).

For purposes
of this discussion, the term “U.S. holder” means a beneficial owner of Pioneer common stock that is, for U.S. federal
income tax purposes, (1) an individual citizen or resident of the United States, (2) a corporation, or entity treated
