Lone Wolf advises they now have pistol variants of the G9 carbine lowers available. These pistol lowers can be had with a short buffer tube, or with a longer tube designed for use with the SIG SB15 arm brace. One of the things that set these lowers apart from other pistol lowers is that they use Glock magazines.
A standard G9 pistol lower with the short buffer tube sells for $419.95. The longer tube version costs $426.95. Lone Wolf is also selling the lowers with a SB15 already installed. These start at $549.95.
Lone Wolf also sells a matching 10.5″ barrel upper in 9mm for the G9 lower. The uppers come with an A2-style flash suppressor and quad-rail. These retail for $779.95.
