Which Gas Pedal® Model to choose?
DOC's CHOICE / OUR BEST VALUE: The newest variant, the BLACK QPQ CM is the same dimensions as our BLACK QPQ MACHINED model and made from 17-4 stainless steel using a catamold process with PIM*. Extremely rugged, no failures reported.
BEST ALL-AROUND Want high durability, and great grip too? Choose our BLACK QPQ MACHINED, identical to our famous original design except it has slot on right side of spindle to facilitate removal. CNC made with billet high alloy steel. QPQ (an advanced version of black nitride, similar to Tennifer™) finish for superior wear ability. Improved Grip Texture, MicroProp™ shape, nice cosmetics too.
BEST Grip Texture ever? STEALTH GRAY or GOLD PVD machined versions. GRAY does NOT match color of SIG Legion models and is similar to a raw steel color. Gold may not be exactly same as Sig "Gold" as there are variations in all Gold pistol parts. PVD parts have a matte highly grippy texture but can be made shiny with lubricating cleaner like Hoppe's #9. Pics do not always show exact color. Our picture of Gold is actual part but my appear different in person
Want to shoot same model as PD? Our BLACK CM - LEO VERSION is slightly less expensive than our other models but has same precision and dimensions. Works exactly the same. Made with Catamold™ PIM* technology, the same process used in critical aerospace components with a black QPQ finish. You do not have to be LEO to order this.
For those that want the best of best, our latest limited quantity BLACK QPQ STAINLESS STEEL LTD III is for you. The LTD III version has the exact same internal dimensions as the BLACK QPQ MACHINED, however it is made from billet stainless steel 17-4... this is not your father's stainless! 17-4 is much stronger and harder to mill than regular stainless (316/416-series). It has been precisely machined to have superior cosmetics. We protect it even more with QPQ, a super durable black nitride finish variant with a satin finish. Normal appearance is a satin finish, but can be made flatter with rubbing alcohol or more shiny with gun oil Like Hoppe's #9. The LTD III version is the latest in the LTD series by adding a slot on right side of spindle to facilitate take down.
On a budget and okay with a surprise? Want to explore the Opposable Grip? BLEM are quality part with EXTREMEDUTYTUFF™ 90 day warranty but no returns. Low priced, easy entry level. You never know which model you might get for P320 from CM to LTDIII grab bag, some are first quality discontinued models.
Lefty? Our LEFT HANDED BLACK QPQ is specially made for you. This is for the right side of the gun, for left handers (left hand pulls trigger). The complete assembly has a standard style left side of gun take down lever and a GAS PEDAL® ASSIST thumb pad on the right.
The least expensive model is the STAINLESS CM, still rugged and rust resistant, this part is uncoated and can be used bare or perfect for any custom coatings you might want. It is same shape and function as our BLACK QPQ CM but made with Catamold 17-4 Stainless with PIM*. Ideal for coating your own color. They can be used as is, but without coating Perfect for trainer guns that want to try Opposable Grip Inexpensively.
Want to share the cost with a friend or have a spare for competition use? The best deal is our BLACK CM 2 PACK, two of the BLACK QPQ CM at a discounted price.
*CM PARTS: PIM is particle injection molding, NOT to be confused with MIM (metallic injection molding). Catamod™ PIM from BASF and has similar strength to CNC 17-4 Stainless. PIM uses a special multi step process to fuse and sinter, producing extremely precise and strong part.
NOTE: This Gas Pedal® Assist takedown lever component is designed for normal loads with compatible spring rates. SIG Sauer considers the take down lever to be a consumable part, even their own. Our part should last at least as long as the original part on all SIG models. On the X5 Legion Spectre and AXG expect to replace the takedown after long term or hot loads. Too hot a load with light spring or odd guide rod may cause breakage due to battering of the guide rod against the takedown lever. Pressing down with thumb instead of towards bore can cause same issue. Learn More
Spectre, X5 Legion, AXG expect shorter life because of unstable guide rod. Model BLACK QPQ CM recommended for very high round count or Competition Shooters.

What you need to know about the GAS PEDAL® Assist:
The Problem:
Getting a solid, repeatable grip on a pistol can be difficult—especially under stress. Handguns are hard to control, particularly with hot defensive loads and especially for those with small or weak hands.
The Solution:
The Gas Pedal® Assist transforms pistols into controllable, accurate tools for everyday carry and self-defense and gives the enhanced control necessary for range and competition shooting. Combined with the Opposable Grip technique, it dramatically improves recoil control, speed, and accuracy—even for shooters without big or strong hands.
Why It Works - and why it’s better than simple “muzzle flip” thumb ledges
Pistols can be snappy and hard to control—but muzzle flip is only one part of the problem. Recoil happens in four directions:
1. Up (muzzle rise)
2. Back (rearward impulse)
3. Twist
4. Trigger jerk (yaw or windage error)
Why is the Gas Pedal® Assist better than other products on the market?
The Gas Pedal® Assist, powered by OPP Wing® and MicroProp™ technology, helps you control all four axes. Unlike other thumb rests that only push down, our design engages your thumb actively, pressing forward and inward to counteract recoil across all four dimensions.
Competition and Service proven: The Opposable Grip concept has been proven in competition, having dominated National and World Championships and won consecutive National Champions in 2015, 2016, 2017, 2018, 2019, 2020, 2021, 2022, 2023, and 2024... with rave reviews by shooters and SWAT teams.

- Proven in concealed carry and home defense, law enforcement, and competition.

- 100% Made in the USA.
Doc’s Dream – Now in Your Hands
This drop-in upgrade brings elite control to pistols. Once a winning edge in competition, now it’s a daily advantage for self-defense. If you’ve struggled to manage recoil—or want to shoot faster, better, and more confidently—this is the part for you.
“Just put your off-hand thumb on the Gas Pedal®, and squeeze. It’s that simple.”
Using the Gas Pedal® Assist
- Push your off-hand thumb toward the bore – not straight down.
- If your thumb slips, your angle is incorrect.
- DO NOT start with an old-school “palms locked” grip. Instead, index the thumb first, then squeeze with your support hand.
- A small gap in your palm at the back of the grip is fine—what matters is the squeeze.
Holster Fit
- Adds minimal width, fits most holsters.
- For tight holsters, only minor modifications needed.
- Watch our quick mod video for easy guidance.
- More complex holster? We’ve got a guide for that too.
Important Notes
- This grip method is different from what most common grip technique users are used to.
- No refunds on this part — please read carefully and make sure this is the right part for your pistol before ordering.
Righty or Lefty? Some of our applications have special LEFT-handed options.
Right-Handed = Trigger pulled with right index finger → Pedal mounts on left side (from shooter’s perspective)
Left-Handed = Trigger pulled with left index finger → Pedal mounts on right side
