The Sig P365 Nitron is a premium 9mm micro-compact pistol built for concealed carry and tactical use. Its slim profile and reliable performance make it ideal for everyday carry and sport shooting.
The Sig Sauer P365, 9MM, 3.1″ Barrel, Black, XRAY3 Day/Night Sights packs a 10-round magazine into a sub-compact 9mm frame just 3.1″ barrel length — no single-stack capacity trade-off most guns this size force on you. It’s one of the steadiest sellers we carryand the reason is simple: it’s small enough to actually carry every day and still holds a full 10 rounds.
How Much Does the Sig Sauer P365 Cost?
The Sig Sauer P365 Nitron Micro-Compact 9mm costs $499.99 at Western Sport, down from its $579.99 regular price — an $80 saving. Order it online and we ship it to your local FFL anywhere we can ship. Price verified 2 October 2026.
The Micro-Compact is the original and the smallest of the line. If you are cross-shopping, the short version is this:
P365 Micro-Compact — 3.1″ barrel, 10 rounds, 17.8 oz. The easiest of the family to conceal.
P365X — same 3.1″ barrel, longer grip module, 12+ rounds. Better purchase for larger hands, slightly harder to hide.
P365XL — 3.7″ barrel and a longer slide. Longer sight radius, more comfortable to shoot, still carryable.
P365 XMACRO — 3.7″ barrel with a 17-round grip and integrated compensator. Closest thing in the line to a duty gun.

Common Questions
How much is a Sig P365? $499.99 at Western Sport as of August 2026, reduced from $579.99. Street prices on the Micro-Compact generally run $499–$599 depending on sights and dealer; ours includes the XRAY3 day/night sight package.
Is this the same gun as the standard P365, just cheaper? No — this is the Nitron finish Micro-Compact model specifically, 3.1″ barrel, 10-round capacity. If you’re comparing it to the P365X, XL, or 380 variants, the barrel length and grip module differ; see the comparison above.
What warranty does it carry? Full coverage under Sig Sauer’s original factory warranty, since we’re an authorized dealer.
Is it legal to carry concealed in Texas with an LTC? Yes — the sub-compact frame and 3.1″ barrel make it a common choice among Texas LTC holders specifically because of how easily it conceals appendix or IWB.
Questions before you buy?
Out of Stock? The Same Gun in Another Finish Usually Is Not
P365 availability moves fast, and the configuration on this page is not always the one we have on the shelf. We normally hold several P365 variants in stock at the same price point — different slide finish, different sight package, with or without a manual safety.
Sig P365 Nitron Price — Where It Sits in the Family
The Nitron is the base model of the P365 line, so it anchors the bottom of the family’s price range. Our current price is shown at the top of this page. The table below is the comparison most buyers are actually running: what a step up the range buys you, and what it costs in size and weight.

New vs used
Used P365s trade well below new, and the gap is widest on the base Nitron because there are so many of them in circulation. Worth weighing against two things a private-party used gun does not come with: the SIG factory warranty, and a documented transfer through a licensed dealer.
Why the price moves
Street pricing on the P365 line moves with SIG’s own promotions and with distributor availability, not on a fixed schedule. The price on this page is the live one. If you are comparing against a number you saw elsewhere, send us a message — we will tell you straight whether we can match it.
