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

The 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 PHLser ARC for Surefire 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.


For years, serious shooters have been executing DIY modifications to their WML switches. Using JB Weld, putty, or epoxy, shooters have been improving their speed and consistency of WML activation by building up the small switch nubs on their lights. Drawing on those years of end-user experience, PHLster is excited to announce the launch of their ARC Enhanced WML Switches.

Shipping as a set of three pairs of switch enhancements, the ARC allows users to decrease the distance between activation fingers and switches, optimize their light for right or left-handed use, improve speed and consistency of activation based on their preferred method, and reliably engage the WML switches with gloved or wet hands. Each set of switch enhancements includes a Large, Extra Large, and Extra Large Blank set of switches. The L and XL are both aggressively textured and the XL Blank allows users to shape, carve, and stipple the switches to fit their specific requirements while remaining within a holster-friendly dimension.

If you have short fingers, are tired of compromising your grip to activate the WML, dislike grip switches, need more reach to activate the switches when installed on certain pistols, or just want to make WML activation faster and easier, the PHLster ARC is a necessary upgrade.

Switch installation is easy and requires no permanent modification. The stock switch nubs are easily removed with pliers or a small screwdriver and the enhanced switch end- caps press on to the switch armature bar. And, the ARC switch enhancements fit pretty much every decent WML holster on the market, including Safariland and many, many others.

    these switches make activating the light so much easier. I run a long on the left side of the light for my support hand and a normal length on the right hand side. the only problem I cam across was they were some what hard to install. Phlster knows this is an issue and has to do with Surefire tolerances on the metal switches being increased. Once they are on, they work great.

    I have medium sized hands and was issued a full sized pistol. I found myself having to reposition my grip in order to activate the light momentarily one handed. With the new switch levers, I can now reach the switch without having to reposition my grip. I still believe it’s better to operate the light with my support hand but when clearing buildings, you may need the support hand to open doors while searching. I have these on all my WML’s and would recommend them.

    The switches themselves are great – but the XL options are a bit useless. After installing them, there is so much play that it takes about twice as much pressure to get the switch to activate. The Larges are perfect.
