Price and stock
Availability is good for the SIG Sauer MODX-45: it was in stock at one retailer or another nearly every day in September 2026, and today 4 of the 7 retailers we track have it in stock. Prices barely moved in September 2026, holding around $999.99, so there haven't been real sales lately. Buying today, the lowest price is $999.99 at Brownells, which matches the best price we saw in September.
