Frequently Asked Questions
Glock 31 gen 3 for sale
What's the price range for a Glock 31?
Glock 31 pistols typically cost between $500 and $650 for used models, while new pistols average around $733. Prices vary by retailer and variant. Check our marketplace for current listings.
Did GLOCK discontinue the 31?
The Glock 31 has been discontinued. Both the Gen 3 and Gen 4 versions are no longer in production, and the G31 appears on 2025 discontinuation lists. Check authorized dealers for remaining inventory, and contact Glock directly to confirm availability of any remaining stock.
How much is a used Glock 31?
Used Glock 31 pistols typically cost around $400–$500, with prices ranging from roughly $350 to $600 depending on condition, generation, and seller. Gen 3 and Gen 4 models are priced similarly. Check local gun shops, gun shows, or sites like GunBroker for current listings.
What's better, Glock 31 or 32?
Glock 31 is full-size with a 15-round capacity and longer sight radius, making it better for duty or open carry. Glock 32 is compact, easier to conceal, but holds 13 rounds. Both fire .357 SIG. Choose based on whether you prioritize capacity and control or concealability.
Is .357 SIG stronger than 9mm?
Yes. .357 SIG generates higher velocity and energy than standard 9mm, including 9mm +P. It produces significantly more energy and still outperforms 9mm in ballistic tests, though it costs more and carries fewer rounds per magazine. Whether that performance edge justifies the tradeoffs depends on the shooter's needs.
Is the .357 SIG discontinued?
No, .357 SIG is not fully discontinued, but availability has shrunk. Glock removed its .357 SIG chamberings from their website around 2023, casting doubt on active production. Our marketplace still shows 21 retailers stocking variants, with one currently in stock. Ammunition remains available but less common than 9mm or .40 S&W.
Why is the .357 SIG not popular?
.357 SIG peaked in the 1990s but lost ground to 9mm and 10mm Auto. Its high operating pressure accelerates wear on some pistols. Ammunition costs more and reloading is complex. Many buyers seeking a powerful cartridge chose 10mm instead. 9mm's lower recoil and cheaper ammo made it the dominant choice.
What are the disadvantages of .357 SIG?
.357 SIG's main drawbacks are limited ammunition availability and higher cost compared to 9mm or .40 S&W. High operating pressure accelerates wear on springs and other components. Reloading components are scarce, fewer pistols are chambered for it, and its niche status prevents competitive pricing.
What is the best Glock 357 SIG?
The Glock 31 Gen 3 is the standard full-size .357 SIG option, holding 15 rounds. The Glock 32 offers a compact alternative, and the Glock 33 is subcompact. All are striker-fired and reliable. The G31 is most common, typically priced around $499–$600 new.
Is Glock Gen 3 better than Gen 4?
Neither is objectively better—it depends on your priorities. Gen 4 adds interchangeable backstraps for custom grip fit and a redesigned recoil spring. Gen 3 offers simpler design, lower cost, and decades of proven reliability. Both function reliably; Gen 4 suits shooters wanting ergonomic customization.
Why do people prefer Gen 3 glocks?
Gen 3 Glocks appeal to traditionalists who value proven reliability, lower cost, and a simpler single recoil spring design. Many shooters prefer the classic ergonomics and finger grooves over later generations. Aftermarket support remains extensive, and the platform has decades of documented performance behind it.
Why does Glock still sell Gen 3?
Glock continued producing Gen 3 models because they remained popular, cost less than newer generations, and fulfilled law enforcement contracts. Many shooters prefer the Gen 3 grip texture and finger grooves. However, Glock is now discontinuing most remaining Gen 3 and Gen 4 models. The expired Gen 3 patents make it an open-source platform.
Is Gen 3 Glock being discontinued?
Glock has discontinued multiple models across generations and calibers, including the G31 in .357 SIG and Gen4 and Gen5 variants of popular models like the G17 and G19. The discontinuations extend beyond any single caliber or generation. Check with retailers or Glock directly for the current status of a specific variant.
