The Original Jackass Rig™ was reintroduced for Galco International’s 30th Anniversary. Galco’s predecessor, "The Famous Jackass Leather Company," first introduced this shoulder system in 1970. It features a horizontal holster that can be adjusted to a more diagonal carry position than our Miami Classic or MCII, attaching to the harness with our swivel connectors.

The ammo carrier has a streamlined yet secure design, while the Premium Center Cut Steerhide™ harness provides unparalleled concealment opportunities, greater adjustment and comfort. All four points of the center cut steerhide harness can pivot independently and are connected by our unique clover-shaped Flexalon™ swivel back plate, which is a Galco trademark.

The Jackass Rig includes holster, harness, ammo carrier and a set of harness fasteners. The Jackass Rig is fully modular, and optional accessories may be purchased separately.

Made for semiautomatic pistols, the Jackass Rig is available in right and left hand draw in black finish.

Harness fits chests to 56".

Everything I was hoping for!
Fantastic craftsmanship and excellent quality leather. DO be patient and take your time breaking it in, it will take a few weeks. You will be rewarded with an amazing fit and comfort for an EDC. Like other reviewers, I found the holster to be very tight for my Springfield Armory 5” 1911 even after an overnight in two freezer bags stuffed into it. But it is conforming to the firearm nicely now after a few weeks, patience is the key. DO NOT cut the straps until you have been wearing this harness for at least a month.

No Better Way To Carry Full Size
I carry a Glock 21 (Full Size .45). I was using a galco IWB for this purpose but needed something different. Took a gamble on their shoulder system and it paid off. You hardly notice you’re wearing it after a few times taking it out. Set up is easy but took me about 45 minutes to get it perfect. Extremely comfortable, very concealable under a suit jacket/blazer or a pull over sweatshirt. Great for concealed carry when either of those garments are an option.

Also it looks great! As it’s the summer now, I’ve been open carrying a bit too. Works like a dream and makes me feel cool.
