1911 FRT: Forced Reset Trigger Fitment & Install Guide

A 1911 forced reset trigger is a machined replacement for the hammer strut, the small link that runs from the hammer down to the mainspring housing. As the slide travels rearward and cocks the hammer, the strut converts that motion into forward pressure on the trigger, pushing it out of your finger and through reset before you have consciously released it. Re-apply pressure and the gun fires again. It is still one round per trigger pull; what the strut deletes is the human reset, which is the slow link in any fast string.

This is a genuinely different mechanism from the FRTs most shooters have handled. An AR-15 forced reset trigger is a drop-in cassette driven by the bolt carrier, covered in our Super Safety guide, and a Glock FRT is a trigger-group swap, covered in our Glock forced reset trigger guide. On a 1911 the trigger bow, sear, and disconnector all stay factory. The single part you are buying lives under the hammer and takes the full mainspring load every cycle, which is why all four kits are machined from steel and sold in calibrated sizes rather than as one universal part. For the mechanism, the category history, and how each platform’s FRT differs, our forced reset trigger buyer’s guide is the hub.

A Marvel Cut is a permanent machining operation on the slide that lowers the disconnector rail height, correcting disconnector timing and reset drag on tuned 1911 and 2011 pistols. Vulcan Machine Werks sells it as a $100 gunsmithing service, and three of the four kits state that they require one: the Texas Trigger USA 1911/2011 FRT ($60), the Pembleton & Sons DILLINGER ($70), and the Redacted Industries TRX1911 ($89). Pembleton & Sons and Redacted both call the cut necessary for smooth operation. Continental Customs does not list the requirement on its product page for the 1911 C.A.R.T. Kit ($99.99).

Price the guide’s cheapest path honestly: the $60 Texas Trigger strut plus a $100 cut is a $160 project, and the cut cannot be undone. That reorders the field. Against a Marvel Cut the $39.99 spread between the cheapest and the most expensive kit stops being the number that decides the purchase, and material, install documentation, and frame fit become the deciding factors instead. Send the slide out first or line up the gunsmith before the strut arrives; a 1911 with an FRT strut installed and no cut is a pistol you cannot shoot.

The install is a mainspring housing and hammer job, not a trigger job. Drive the mainspring housing pin out from the left side of the frame with a 1/8 inch punch, slide the housing off the bottom while controlling the compressed mainspring, then pull the hammer, lay it sideways on a bench block with the strut pin hole supported, and drive out the strut pin. The forced reset strut goes back in the factory strut’s place. The trigger bow, sear, and disconnector are never touched. An experienced 1911 owner is looking at under an hour with a pin punch and a bench block.

Two things decide whether it runs. The first is sequence: the Marvel Cut is slide work, so book it before the strut lands rather than after. The second is strut size. Frame and hammer tolerances vary enough between 1911s that one length will not run in every gun, which is why Texas Trigger USA and Redacted Industries ship four calibrated struts while Pembleton & Sons and Continental Customs each ship three. Fit the size the maker specifies for a standard frame first and step up only if the strut will not seat and cycle. Redacted Industries is the only maker that supplies a written procedure, a 22-step disassembly and reassembly document; Texas Trigger USA states it provides no installation or troubleshooting support.

Function check on snap caps before live fire. Hand-cycle the slide and confirm the hammer stays cocked, both safeties engage, and the trigger runs forward under strut pressure without the hammer following it down. Hammer follow, doubling, or a light strike means the gun goes to a smith, not to the range. If this is deeper into the frame than you want to go, the bolt-on end of the platform is covered in our 1911 upgrades guide.

Fitment on a 1911 FRT is defined by geometry, not by brand: a full-size frame running a standard hammer strut. All four makers sell their kits as 1911/2011 units in 9mm and .45 ACP, because a double-stack 2011 uses the same hammer, sear, and strut geometry in a different grip module. Texas Trigger USA, Pembleton & Sons, and Redacted Industries all state full-size fitment only, and Texas Trigger and Pembleton both explicitly exclude compact models. No maker publishes an Officer or Commander-length variant, and no maker names a specific host brand as verified. Continental Customs is the only one that names a lineage at all, stating the C.A.R.T. runs in any pistol using a standard hammer strut, including Series 70 guns.

The sizing matters more than the spec sheet suggests. Frame and hammer tolerances vary enough between 1911s that a single strut length will not run in every gun, which is why Texas Trigger and Redacted ship four calibrated struts while Pembleton & Sons and Continental Customs each ship three. Continental’s Large is an oversized blank meant to be hand-fit, which is the reason to pick it for a worn or out-of-spec frame that has already been through a smith. If you are still choosing the host pistol, our best 2011 pistols guide covers the full-size double-stacks these struts are sold for, and the comparison tool lines them up side by side.

Buy the Texas Trigger USA 1911/2011 FRT at $60. It is the cheapest kit in the field, it is stainless, and it ships four calibrated strut sizes so one purchase covers a range of frame tolerances. The catch is support: Texas Trigger USA states plainly that it provides no installation or troubleshooting help, so you are on your own or on your gunsmith’s clock once the box arrives.

Step up to the Pembleton & Sons DILLINGER ($70) for the best material spec in the field. It is machined from 316 stainless, the only corrosion-resistant grade any maker here publishes, on a part that carries mainspring load through every cycle, and it ships small, medium, and large struts for the same frame-fit range the other kits chase. It needs the Marvel Cut like the rest, it does not run in compact models, and returns carry a 10% restocking fee.

Pay the $29 premium for the Redacted Industries TRX1911 ($89) if you intend to do the work yourself. It is the only kit of the four that ships a written 22-step disassembly and reassembly procedure, and on a part that lives under mainspring load, a documented sequence is worth more than $29 of strut. Its 14-day warranty is the short end of the field.

Take the Continental Customs 1911 C.A.R.T. Kit ($99.99) when the host gun is old, worn, or out of spec. Its three sizes are graded for exactly that (Small for most guns, Medium for older and looser pistols, Large as an oversized blank you fit by hand), and Continental is a forced-reset specialist that also builds kits for Glock, AR-15, MP5, and KRISS Vector. It is the most expensive of the three and its page does not publish a material spec.

The mechanism fires one round per trigger function, so it is not an NFA machine gun: no Form 4, no tax stamp, no registration. The federal picture for a 1911 FRT specifically is less settled than it is for a rifle. The 2025 Department of Justice settlement that resolved the FRT fight covers rifles and pistols that feed ahead of the grip, such as AR and AK pistols. It does not extend to grip-fed handguns, where the magazine loads into the trigger hand. A 1911 and a 2011 are both grip-fed, which puts them in the same grayer federal lane as a Glock or Canik FRT rather than the settled rifle lane. Buy with that uncertainty understood.

Sixteen jurisdictions restrict forced reset triggers or rapid-fire activators outright: California, Colorado, Connecticut, Delaware, Florida, Hawaii, Illinois, Maryland, Massachusetts, Minnesota, Nevada, New Jersey, New York, Oregon, Rhode Island, and Washington D.C. Florida is legally ambiguous rather than a named ban, and makers decline to ship there for that reason. State law on these devices moves fast, so confirm yours before ordering.

A maker’s no-ship list is a shipping policy, not a legal opinion. Texas Trigger USA will not ship its 1911 FRT to CA, CT, DE, FL, HI, IL, MA, MD, MN, NJ, NV, NY, OR, RI, WA, or DC. Washington state does not ban forced reset triggers; the state’s rapid-fire language reaches mechanisms that fire without a trigger press per shot, which an FRT is not. The vendor declines the sale anyway. Treat the ship-to list and your state’s actual statute as two separate checks.
