Modlite PL350 G3: Switch Stop Screw, Metal Lug, 1600mAh Cell

The PL350 G3 changes three things and leaves the rest of the light alone: a switch stop screw, an all-metal 1913 Picatinny rail lug, and a 1600mAh 18350 cell. Output is unchanged, the body is still 4 inches long and 1.25 inches in diameter, out-the-front battery swaps still work, and standard-size Modlite heads still thread on. This is a quality-of-life revision driven by user feedback, not a new light.

That framing matters for anyone deciding whether to replace a working G2. Nothing about the beam, the mount, or the holster fit changed, so a G2 owner who never had a problem with the switch has no performance reason to move. The reason to move is the switch stop screw, and Modlite sells the G3 body on its own for $139 if that is the only piece you want.

The switch stop screw threads into the switch housing and physically blocks travel on one side, so the switch can only be driven from the other. It is configurable for left- or right-handed setups and ships with a dedicated Allen key. Modlite recommends blue threadlocker during installation.

The problem it solves is specific. The G2 switch is crisp enough that shooters running the light hard would push past the off stroke and reactivate it, which is a real failure under stress on a light that is supposed to be a momentary tool. Blocking one side of the travel gives the off stroke a hard boundary while leaving the on stroke exactly as tactile as it was. Modlite's own framing is that it lets you attack the controls without hedging on the shutoff.

The G3 adds an all-metal 1913 Picatinny rail lug to the box, alongside the universal polymer lug and the polymer 1913 lug that shipped before. Modlite recommends the metal lug specifically for metal-frame handguns, which in practice means 1911 and 2011 pistols and other steel- or aluminum-framed hosts.

The logic is straightforward. A polymer lug clamped against a steel dust cover takes the abuse on the softer side of the interface, and on a hard-recoiling metal frame that shows up as slop over a high round count. Moving the lug to metal puts a harder material against the rail. Polymer-framed hosts like a Glock or a P320 stay on the polymer lugs, where the two materials wear more evenly.

Both full-size packages cost the same, so the decision is purely beam profile. The PLHv3 head produces 1,500 lumens and 60,000 candela at 6,500K, a balanced hotspot with usable spill that works indoors and outdoors. The OKW v2 head produces 1,300 lumens and 95,000 candela with a much tighter hotspot, which is the pick when you need reach: rural property, a magnified optic on a host gun, or punching through window tint and fog.

For a house gun, take the PLHv3. The extra 200 lumens and the wider spill do more work at room distances than 35,000 additional candela you cannot use inside 15 yards. We covered the PLHv3 launch and the OKW v2 beam profile separately if you want the full numbers on each head. The same heads run on rifle bodies, which is the subject of our AR-15 weapon light rankings.

The compact body gets the same G3 treatment: switch stop screw, metal 1913 lug, and the 1600mAh cell, at $309 without the charger. It runs the shorter AMP head at 876 lumens and 18,000 candela in a 3.54 inch body, which is roughly half an inch shorter than the full-size light.

That trade is worth taking when the full-size light overhangs the muzzle on a compact host and forces a longer holster. It is not worth taking for output alone; 18,000 candela is a large step down from the 60,000 the PLHv3 delivers. Both bodies accept both head sizes, so a compact body with a standard head is a legitimate configuration if you want candela on a shorter switch housing.

Budget for a PL350-specific holster and at least one spare cell. The PL350 body does not index in a SureFire X300 shell, so an X300-cut holster is not a substitute, and the G3 changed nothing about the body profile, so anything molded for a G1 or G2 PL350 still fits. Our light-bearing holster rankings cover the shells that list PL350 fitment.

On power, the constraint is that Modlite heads do not run on CR123 cells; the manufacturer warns that they can overheat in this body. That rules out grabbing lithium primaries off a shelf mid-class. Thirty minutes of runtime is short by pistol-light standards, and the practical answer is the out-the-front battery swap: a charged 18350 in a pocket goes in without dismounting the light. The two-cell XTAR USB-C charger is bundled in the $329 package. For how the PL350 stacks up against the Streamlight and SureFire options at a third of the price, see our ranked pistol lights guide, or compare specs side by side.

Buy the G3 if you are entering the platform now, or if the G2 switch has ever turned your light back on when you meant to shut it off. Those are the two clean cases. At $319 it is roughly double a Streamlight TLR-7A and it asks you to manage rechargeable cells, which is the honest cost of 60,000 candela on a handgun.

G2 owners who have never had a reactivation should buy the $139 G3 body and move their existing head over rather than replacing the whole package. Owners of metal-frame competition guns get the second reason to move: the metal 1913 lug is the right interface for a 2011 dust cover and it was not previously in the box. If you are still assembling the rest of the gun, the builder will show which pistol lights clear your host's rail.
