The old Carry Comp and the Staccato XC are essentially a full rail 5" gun, so it will be larger & heavier than the Marauder. If you want small, then a Staccato C2 Duo, but it won't have a comp. To add a comp to the gun you need to FIT a threaded barrel, as with 1911/2011 they aren't drop-in like polymer guns.
