.40 S&W Market Analysis
.40 S&W's market price index compares posted prices for the same products over time, whether they are in stock or sold out. The latest index is 0.1% below 30-day avg. The current signal is HOLD; it measures market pricing, not a discount on an individual offer.
The index starts at 100 for each comparable series. Price changes are combined using equal-weight geometric price ratios. New or disappearing listings do not create a price change. If no products match between observations, the chart starts a separate series and does not infer a return across that break. Available records span 2026-04-05 through 2026-10-26.
For shopping now, the lowest in-stock price is $0.332 per round at Gun Place. 323 of 351 current listings are in stock across 29 retailers.
Quotes come from the existing retailer checks. Dates without observations are not filled in. Posted dollar medians are available in the history table; unlike the index, they can change with the product mix. Prices exclude shipping and tax. Check the retailer's page before purchasing.
