Sig Sauer just released the M17X and M18X on the commercial market. These new guns use the actual M17 and M18 slides as found on the models delivered to the military and are equipped with the Romeo-M17 optic. These guns have a Coyote X-Carry grip with a magwell and no manual safety which differs from the actual military model. Each gun ships with (3) 21-rd magazines. You can use P320 Legion 17rd magazines which are compatible with the mag funnel, however the 21rd magazines are more cost effective due to the polymer floorplate.
These guns are now shipping from SIG and can be found on our webstore:
