Improve speed and consistency of weapon mounted light activation with user configurable and modular extended switches. 

The Surefire ARC comes as a set of three pairs of switches. All three pairs are over-sized compared to stock and the set includes a Large, XL, and XL blank set. The Large and XL are aggressively textured, improving activation with gloved or wet hands, and requiring less precise dexterity to activate the WML. A blank set in XL size is included for users to carve, modify, or stipple to fit their individual needs. 

Large, XL, and stock switches can be mixed and matched, to optimize the WML for right or left-handed use, based on your preferred activation technique, decrease the distance to the switch on some models of firearm, or to simply improve momentary or constant-on activations.

No permanent modifications to the WML are necessary to install the ARC. The original switch caps are easily removed with a small screwdriver or pliers and the ARC switch enhancements press directly on to the switch armature bar. Please watch the instruction video prior to installation. Be aware that the switches are right and left-hand biased, so pay attention to the markings on the ARC switch enhancements. 

Depending on the age of your light, manufacturing tolerances, and their intended use, some users may want to apply a tiny dab of adhesive to the switch armature bar as a final step in their installation, after determining their optimal switch configuration. 


The Streamlight ARC comes as a pair of two complete switch paddles. One is symmetrical and the other is asymmetrical. Both are larger than stock. The asymmetrical paddle can be reversed depending on which side you prefer to have the longer switch. Kit includes all tools required.


The PHLser ARC for Surefire and Streamlight WML’s fits all popular light bearing holsters.

We accept returns of the ARC in original, intact condition. In the event of defect, we are happy to send a replacement unit. We cannot accept returns of units which have been snapped off the injection tree or installed on lights.

    Absolutely amazing although the textured paddles are a bit sharp i had to file them down a little, but no big deal!

  2. jb9881255 (verified owner)

    Excellent product! Somebody should have come out with this years ago! Only reason it’s 5 stars is I couldn’t give it 6!

  3. zarathean83 (verified owner)

    The short textured one is ideal for me, the longer ones cause my switch to flex (its the switch not the button being loose so no points lost) i highly recommend these and a Floodlight

  4. Scotty Noble (verified owner)

    I use the short textured ones as well… 10 mos out on a 27 year retirement, former assistant range master, etc, etc. Never knew there were accessories to make these lights better. Great stuff!

    Great product goes well with my floodlight holster any many of my guns.

  6. Sharp (verified owner)

    Simple DIY solves the problem that my finger can’t press the switch!!

  7. KEVIN GRAY (verified owner)

    I like it much better, easier to reach the switch on my x300, just may have to use extra large switch for suppoet hand and large on right hand, I will see, much better then before and it has not effected my holster fits just fine

  8. Damon Webb (verified owner)

    Much more ergonomic than the factory SF paddles. I’ve smaller hands, & the X300 on my 509 was barely accessible. Now I can reach either side quite easily. Thanks! As I switch out my Inforces for SFs, I’ll be getting more…

    I like big guns (and I can not lie 🙄)….Sig X5, FNX45. These extended paddles make it easier (and safer) to activate your light. No more manipulating your grip to reach those stubby OEM paddles.

    They do exactly what they are meant to provide easier manipulation of the WML. I chose to run the long/short on a Polymer 80 Glock 19 build to bring the switch a little closer to aid in function without losing grip position on the pistol using my dominate hand (right) and the shorter leg of the switch extension stays to my offhand (left) to be easily manipulated by my offhand thumb. Great product.

  11. Shawn Weed (verified owner)

    Installed these shortly after a no/low light pistol course showed me I need a bit of texture on my X300U switches so momentary Use is a bit more consistent. I also realized that during one handed firing my fingers were just long enough to reach the factory switches. It led to inconsistent activation of the WML. I added the long switch on the right side and the shorter on the left. While the X300U is completely useable for me with the factory switches, the ARC switches make it the perfect WML.

    Great product and crazy fast shipping. Fixed the problem on my FNX.

  13. nick Bowling (verified owner)

    streamlight tl1 very easy installation havent used it much but seems very sturdy and well thought out

  14. fullm3taljacket (verified owner)

    The reach on my new carry gun was too far for the standard paddles. With the PHLSTER ARC, it is now perfect. Shipped quickly and was delivered quickly. Highly recommended for pretty much everyone.

  15. beatle613 (verified owner)

    The fact that I no longer have to break my traditional firing grip to reach the switch w/ my support thumb make the ARC switches great for me Installation was simple & go on really solid (X300u). If enough people have a problem w/ something, someone is bound to make a solution. Thanks Phlster for the solution to my problem. 🇺🇸

  16. supercoop03 (verified owner)

    These are great, especially one a gun with a larger trigger guard. I am using a Beretta 92 w/ X300 and the trigger guard on the Beretta is big enough that I could just barley reach the stock switches. These were easy to install and fit perfectly. Now the switch is right there at the end of my finger without shifting my firing grip.
