Selling somthing special here. My Custom SIG P320 M17 with 4 magazines. I've done a lot of customizing to this to make is it's own CQB beast! My goal was to have a pistol that was capable enough to run indoor CQB by itself, as I did not have a CQB rifle or carbine. Here is the list of add-ons equipped to this pistol: Pro-Arms CNC Aluminum Threaded Outer Barrel MITA Enhanced Stainless Steel 120% Dual Recoil Spring Laylax Nine Ball Tight Bore Inner Barrel (6.03mm / 105mm) SIG Sauer SIG AIR Micro Reflex Dot Sight The quality of this pistol feels amazing, theres no play in the slide, everything fits together well. The slide travels smoothly and snaps back due to the 120% dual recoil spring. The cost of all these items new was $470 and this pistol is still practically brand new, I tested it after I put all the new parts in and it ran flawlesly, then I put it away and never went to to indoor CQB.
