These V2 magazines are designed to fit into the X Macro grip module (they will work in any smaller grip module as well, but will not blend to the bottom of the frame) but keep your capacity to 10 rounds with no debate on the magazine capacity as they use standard Sig Sauer 10 round magazines.
The V2 will also work with the XMacro Tacops, Sig Sauer Magwell and many other aftermarket magwells.
The magazine bases now come in two length options. Low Profile for the minimalist amount of mag base below the grip module to reduce profile for CCW (Will be hidden inside a magwell) and Extended for extra weight and grip as it will extend below the magwell on most magwell equipped grip modules.
The bases are machined from aluminum and hollowed out to be lightweight if that's what you want OR you can add Tungsten weights into the cavities to make back the weight lost from the missing rounds. Adding weights reduces felt recoil and makes the mags drop faster and more reliably from the gun. (Weight kits sold separately).
These adapters will keep the same capacity as the original magazine. They simply replace the baseplate and use the same internals from the stock magazine so NOTHING is changed about how the magazine functions or it's capacity. If you wish to lock the baseplate firmly in place (for repeated dropping such as with competition use we recommend the locking plate available here). We include the original stock magazine baseplate.
These magazines maintain "compliance" when used in grip modules that were designed for higher capacity magazines. Baseplates can be used with the original spring plate (as they come froom us) or can be bolted through and into an internal locking plate (available separately) to allow repeated tactical reloads and normal range use without any risk to the base plate moving.
Made in the USA and anodized to be very robust these will put up with abuse and come with a Lifetime factory warranty against defects in design or manufacturing (does not cover cosmetic issues from use or dropping mags). Dropping on concrete/rocks may damage the mag base cosmetically and is not covered under warranty, but functionality is always covered.
