.357 Magnum Price By Firearm Model
The .357 Magnum caliber is heavily dominated by double action revolvers, which fall into a few distinct price categories.
- Entry Level Revolvers:Brands like Taurus offer compact concealed carry revolvers like the Model 605 starting around $350 to $390.
- Mid Tier Revolvers:Workhorse duty models like the Ruger GP100 usually retail between $799 and $899.

.357 Magnum MSRP vs Retail Price
Ammunition manufacturers consistently list MSRPs that are 10 to 20 percent higher than the true street price. A box of Armscor 158 grain FMJ might have an MSRP of roughly $32.00 but can be found at retail for $28.00.
For firearms, standard revolvers chambered in .357 Magnum also sell below MSRP. The Ruger GP100 carries an MSRP of $1,069.00 but is widely available for around $800. However, highly sought after premium models like the Colt Python often sell exactly at MSRP due to high demand and prestige.
Why Is .357 Magnum So Expensive?
While the firearms range wildly in price from budget to luxury, the ammunition is notoriously more expensive than semi automatic pistol calibers. The high price tag of the cartridge is driven by the sheer amount of material required.
A standard 9mm cartridge uses a small casing and lighter powder loads. A .357 Magnum uses a long, thick brass casing and massive powder charges designed to push heavy 158 grain bullets at high velocities. Furthermore, .357 Magnum is a rimmed cartridge built for revolvers and lever actions, meaning it does not benefit from the massive, global military mass production that keeps calibers like 9mm or 5.56 NATO incredibly cheap.
Used .357 Magnum Firearm Price
Buying a used .357 Magnum revolver or lever action rifle is a great way to save money. Because revolvers do not eject casings and feature robust solid frames, they hold up remarkably well over decades of use.
| Condition | Typical Price Range | Notes |
| New (Complete Firearms) | $350 to $1,500 | Price depends entirely on brand tier and finish |
| Used Good Condition | $250 to $700 | Budget brands like Taurus and older Ruger models |
| Used Excellent Condition | $700 to $1,100 | Factory complete mid tier to premium models |
| Collector Models | $1,500+ | Pre lock Smith & Wesson or original vintage Pythons |
Note: Used market figures are estimated market observations based on secondary sales rather than official pricing.
