About the Kahr Arms PM40

The Kahr Arms PM40 in .40 S&W is a semi-automatic rifle from Kahr Arms — Worcester, Massachusetts maker of slim CC pistols — the K9, P9, and CM9 series. Within the catalog this configuration serves law enforcement (largely retired), CCW, duty, and its 2026 used-market position is supported by an active dealer network, available parts, and a stable supply of buyers willing to transact at the price bands documented below.

Brief History & Lineage

Kahr Arms was founded in 1995 by Kook Jin Moon. The Kahr smooth-DAO trigger and narrow polymer frames defined the modern slim 9mm category and predated Glock’s own slim G43 by a decade. Within the catalog, Kahr Arms positions itself among peers including Glock, Smith & Wesson, Walther Arms.

Variant & Year-of-Manufacture Notes

The Kahr Arms PM40 has been offered across multiple production years with variation in stock material, finish, and barrel length. Early-production examples typically command a modest premium over late-production guns of the same configuration. Watch for aftermarket modifications — refinishes, drilled-and-tapped receivers on classic pieces, replacement stocks, and trigger swaps — all of which can shift used value. Original-condition examples with matching serials, factory boxes, and manuals trade at the top of the range for the model.

Ammunition & Shooting Notes

The .40 S&W is used for law enforcement (largely retired), CCW, duty. 165gr-180gr loads dominate; surplus is shrinking as agencies switch back to 9mm. Modern factory loads from American, European, and Asian manufacturers all run well in this platform, and reloaders enjoy a wide range of bullet and powder combinations.

How It Compares

The Kahr Arms PM40 occupies a market position comparable to offerings from Glock, Smith & Wesson, and Walther Arms. Buyers cross-shopping these brands typically prioritize concealed-carry buyers — and once they’ve committed to Kahr Arms, brand loyalty tends to be strong because of dealer network and parts availability. Used-market resale for a comparable-condition gun from these peer brands trades within roughly ±15% of the Kahr Arms PM40 depending on the specific variant and year.

What’s a Used Kahr Arms PM40 Worth?

Private-sale ranges for a working, no-rust PM40 in 2026 fall in four bands:

• Beater / heavily used: $550–$750 — significant wear, action functional, may need cleaning or minor service
• Average / honest used: $700–$1050 — normal handling marks, mechanically sound, ready to shoot
• Excellent / lightly used: $950–$1450 — minimal wear, clean bore, original box and paperwork a plus
• New-in-box or unfired: $1200–$1750 — at this price, the calculation usually flips toward buying new instead

Add a premium for documented early-production examples, original box and accessories, or limited-run variants. Subtract for refinished surfaces, aftermarket modifications a buyer would have to reverse, or signs of hard use.

Who Buys It?

The typical Kahr Arms buyer profile includes concealed-carry buyers, slim-9mm fans, Kahr-trigger devotees. The semi-automatic rifle format and the .40 S&W chambering further focus the audience. Used-market liquidity is solid — list a clean example at fair market on GunBroker, Armslist, or a local board and it generally moves inside two to three weeks. Dealer trade-in offers typically run 20–30% below private-sale; if you have time to list, private sale captures the premium.
