The Timney single stage trigger is installed at the factory and has the consistent, light pull that competition shooters want without needing aftermarket work. The Magpul SL-K stock adjusts to length of pull and folds for storage or transport. The aluminum M-Lok handguard keeps weight low and accommodates lights, foregrips, and other accessories without tools. The MPX uses proprietary SIG magazines, which is a compatibility consideration for buyers who may already have a supply of a different 9mm magazine. ## Frequently Asked Questions **Q: What caliber is the Sig Sauer MPX?** A: The Sig Sauer MPX is chambered in 9mm Luger. **Q: What is the barrel length of the Sig Sauer MPX?** A: It has a 16-inch barrel. **Q: How many rounds does the Sig Sauer MPX hold?** A: It has a 35-round capacity and ships with one 35-round magazine. **Q: Who makes the MPX?** A: The MPX is made by Sig Sauer. **Q: What type of firearm is the Sig Sauer MPX?** A: The Sig Sauer MPX is a semi-automatic pistol caliber carbine. **Q: Is the Sig Sauer MPX Competition barrel threaded?** A: Yes, at least one configuration features a threaded barrel, as noted in the product listings. **Q: What trigger does the Sig Sauer MPX Competition have?** A: It is fitted with a Timney single stage trigger, installed at the factory. **Q: Where can I buy the Sig Sauer MPX?** A: Compare current vendor offers on this page. ## What Reviewers Say *Quoted verbatim from YouTube reviews.

Accuracy and trigger quality are the most praised attributes. The factory Timney trigger is specifically mentioned as one of the best factory triggers available in a PCC, which saves competitors money on aftermarket upgrades. Recoil management from the gas piston system is well-regarded. Owners compare it favorably to blowback-operated PCCs and credit the smoother impulse for faster target transitions in stages. Build quality and Sig's fit and finish get consistent positive mentions. The rifle handles reliably across various 9mm loads. The 35-round capacity is practical for competition stage design and owners appreciate it. The SIG proprietary magazine system comes up regularly as a practical limitation. Buyers who already own Glock or CZ magazines for their pistols have to maintain a separate magazine ecosystem. Price is consistently described as high but accepted as the cost of a competition-ready package. SIG customer support feedback is mixed. Some owners report good experiences, others have faced delays. Customization discussions focus primarily on optics, as the rifle is otherwise competition-ready from the factory. ## Pricing **15 offers available** | Vendor | Price | |--------|-------| | Gunbuyer Com | $2199.99 | | Brownells | $2199.99 | | RK Guns | $2199.99 | | Guns Com | $2199.99 | | Kygunco Com | $2199.99 | | Palmettostatearmory Com | $2199.99 | | Sportsmansguide Com | $2199.99 | | Buds Gun Shop | $2199.99 | | Impactguns Com | $2199.99 | | Grabagun Com | $2199.99 | *...and 5 more offers* ## Reviews **Average Rating:** 5.0/5 (1 reviews) > **joel** (5/5): I’ve been waiting to get my hands on the SIG Sauer MPX for ages, and it was totally worth it.
