Patriot Defense | Tanfoglio Interrupter R5

Patriot Defense | Tanfoglio Interrupter R5


Parts included: R5 Interrupter & Pin

NOTE: For a trouble free install with the R5 interrupter we recommend you have the Xtreme Sear and Titan Hammer installed on your pistol. These two items are a must if your looking for a trouble free install on your firearm.

Please read the below product description before purchasing. Some pistols will require fitting due to the vast amount of machining tolerance variations in these pistols. The supplied pin is designed to float in the hammer pin holes, use grease to aid in assembly and keep the pin from falling out. Please contact us should you have any question regarding fitting or modifying your R5 interrupter. 

The number one complaint Tanfoglio owners have about their guns…..…the trigger, and its pre-travel.

The Patriot Defense Optimized R5 Interrupter was conceptualized and created off the extremely popular BOLO interrupter. Its sole purpose was to give those who aren't experienced in the inner workings of a Tanfo the ability to have a drop-in part.. Precision CNC machined and heat treated for optimum life and performance to the end user; the R5 Interrupter was machined specifically for the steel frame line of Tanfoglio pistols. Due to feedback we’ve received on the most current configuration of Tanfoglio pistols; most people have the Extreme Sear, and Titan hammer already installed in their pistol. We recommend you already have it installed as well to get the most out of your Tanfoglio firearm and a trouble free install. As mentioned above, with so many changes over the years to the tanfoglio line of pistols the BOLO has required more and more fitting. we set out to have an interrupter that drops in 99% of the time and yields a much better pre-travel than factory. So which one is for you, see below. 


R5- Easy install, very minimal fitting if any is required at all, pre-travel is reduced from factory setup, small amount of take up and solid reset. 

R7- Intermediate install & fitting (material removal will be required from front face of the "leg"), zero- pre-travel can be achieved, and solid reset.

BOLO- Advanced install & fitting required (material will need to be removed from inner curve, nose of the interrupter, and possibly the edge of the wing), zero pre-travel can be achieved, and audible reset.


Note- Installation and fitting advice of the BOLO is no longer offered, only qualified gunsmith should install this part.

    Drop-in fit with Titan Hammer and Extreme Sear

    Posted by Rudy Segura on Jul 6th 2023

    I bought this R5 to drop into my Stock II without having to file down any surfaces. With the PD Sledge Hammer installed, it wouldn’t drop the hammer in single action mode, but once I put the Xtreme Titan hammer, it functioned flawlessly in both double and single action using the PD Optimized 13# hammer spring. The PD Optimized 12# hammer spring did ignite 99/100 CCI primers, with only 1 light strike every 100-150 rounds

    R5 Dropped In

    Posted by John on Mar 16th 2021

    I have multiple Tanfoglios and have successfully fitted the Bolo in two Stock 2s. However, on my Defiant Limited Pro I could not get the Bolo to function as I would have liked so I went back to the stock Interrupter. When I saw the R5 I thought I’d give it a try, and I’m glad I did. It dropped right in with zero fitting and the reset is now short and sweet.
    Thank you PD for making life just a little bit easier!

    R-5 Install

    For me it dropped right in. Take up almost gone. Will need to see the long term performance. $45, it’s a no brainer.
