Details

Active reset for the SIG MPX. The Rev 2 Slip Trip Kit is the dedicated MPX version, re-engineered specifically for the MPX’s operating system, that lets your 9mm SIG run a Super Safety or ARC-Fire V2 with a standard AR fire control group.

What’s in the kit

Slip Trip: 4140 steel, heat treated, black oxide
Slip Trip Guide: 7075-T6 aluminum, Type III hardcoat anodized with PTFE (Teflon)
Lever blocker built into the guide: no separate lever blocker purchase needed

Compatibility

Fits	SIG MPX and MPX-K, all generations (early gens may need the safety latch removed)
Requires	Super Safety or ARC-Fire + standard AR FCG + this kit
Does not fit	MCX (use the MCX kit) or MPX Copperhead
Rev 2 note	Dedicated MPX version for better reliability; working Rev 1 setups don’t need to upgrade

Trigger advice from the manufacturer: the MPX is known to eat fire control components. While Super Safety-cut Geissele triggers are compatible, AS Designs strongly recommends a generic mil-spec AR FCG: when the MPX inevitably wears a part, you are replacing an inexpensive mil-spec trigger, not a Geissele.

Not compatible with: Atrius Super Selektor, factory Timney trigger, or drop-in cassette triggers of any brand. Do not use any cassette triggers. Some fitment work may be required, as with all aftermarket accessories.

Complete the build

Gunsmith installation recommended. SIG SAUER trademarks referenced for identification only; modification may void the firearm’s warranty.

Laws on assisted reset triggers vary by state and locality and can change. Check the laws where you live before you order. Buyer is responsible for compliance with all applicable laws.
