I have had one  for a while. Actually, this is my second one. The first one had its snaps pop off and after a couple of washes the nice dark black looked grayish.

Sig gave me an RMA to return it and they swapped it out. This one is much higher quality (snaps held, better threading, and dye). My coworker recently bought one and it is too is more improved -- better color, more pockets, longer --  so they are improving the product.

The draw of the jacket is that it has built in holsters on both sides so that you can carry a pistol and magazines without requiring any type of additional holster or rig.

It does this by having two HUGE caverns of pouches on the left and right side. They run the entire length of the jacket and are secured by a full run of velcro. Internally stitched are stretch loops that will hold anything from a pistol magazine to a full size pistol. My P220 fits into the holster!

The jackets are visually appealing. I like the wrist snaps (vs elastic), and the fact that the waist is also non-elastic. These are both reasons I chose it over a comparable 5.11 jacket. Additionally, I really like the look of the collar.

The jacket is very subdued looking. Nothing about it screams "CCW" and there is no visible "SIG" logo to give it away. It is very tasteful. Family members thought it was just another Carhart jacket.

How HUGE is the pouch?
I was able to carry a P220 on one side, and two 5lb bags of beef jerky in the other! It actually makes the 5.11 Vest pouches (which are quite large) seem small! (Link to my 5.11 vest review)

Does it conceal?
Heck yes. Big grip pistols do leave a small bulge (more like a small lump). It doesn't look like a pistol and is in a spot not normally associated with where a pistol would be. In fact, I think it looks more like you have a pack of cigarettes (or politically correct equivalent) in your jacket pocket. Thinner pistols seem to work better. My P225 was almost perfect (as would a P239 also).

Heavy pistols do weigh down one side significantly! You need to offset this with something like a 5lb bag of beef jerky, or you will feel it drag on your neck. It does distribute better than a vest (well, there is simply more material to distribute the weight). My P220 was very doable, however, a 5" 1911 was uncomfortable. Adding weight to the other side to counter balance caused more pressure to be pressed against the back of the neck. Best to keep the 1911 strapped to the waist if you are going to carry it for any length of time.

J-frame BUG (backup gun)!
I don't know if they did it on purpose but the outside pockets (one on each side for your hand) is PERFECT for S&W J-frame snub nosed revolver. I mean ridiculously perfect. Other owners (ok, 2) have remarked the same thing to me independently.

The bad that has been corrected?
Some features, that mine doesn't have (that I complained about previously) have been corrected! My friend's has them now...

Longer. Concealing a full 5" 1911 and bending over is now possible.
More pockets, mine only has the two caverns and two outside. The new ones have at least one more, and you can now actually carry that pack of cigarettes.

Each generation seems to have better dye to retain color.

Things I would still like to see..
A pull tab, or some quick way to access your pistol. Currently it requires some coordination to separate the velcro to gain access. It is also LOUD to hear the entire length of velcro unhook.

Maybe it is just because I am in the Pacific Northwest, but I would like to see a hood, whether it be a snap/button on or a roll up kind.

The weight/thickness. It is not really a good cold weather jacket, but it is too heavy/thick for a warm weather jacket. Not too bad for out here where it is always damp and dark but otherwise limited seasonally. I would like to see something lighter and either a vest liner, or a separate heavier version.

Conclusion:
I really like this jacket and Sig continues to improve it.

Musings about bail out bags - pt1: From the nightstand to grab bag (i.e. grab it during bump in the night or when the FD makes you leave because of fire)

Lots of folks have a "night stand" gun. I do. But what happens when you need to be mobile with the pistol? Do you go around/out with it in hand? Depending on where you live that may not be such a good idea.

I usually have a holster nearby but pajamas don't make a good platform. A possible solution? The "man bag"....I have posted about my Maxpedition Fatboy Jumbo a few times now and maybe I am just trying to justify its expense, but I am finding that it comes in more handy than just as a quick way to pack a pistol while walking the dog in the summer (and carry dog treats and water). It makes a great "grab bag."

Think of this scenario--there is loud knocking at your door in the morning. A voice says: "This is the Fire Department, you need to evacuate your house immediately!" -- Glancing out the window you see a fire truck hooking up houses to your nearby hydrant.

I give you this example because it happened to us. Our next door house was on fire and the fireman said that we were potentially only a minute or two away from our "flashing" and being in flames too!

We literally grabbed pants, jackets, shoes and anything important into the safe on the way out. My Glock 23 on the night stand came with me in my Maxpedition. Along with a couple spare mags (and dog treats and poop bags).

Luckily, the FD came in time to put out the fire and save our house from "flashing." The neighbor's house was not so lucky. It was condemned from fire/smoke/water damage.

But what if our house had caught on fire? Scary thought but it could happened through no action of our own. As much I like my Maxpedition it would not make a good bag if we had to stay in a hotel overnight (or longer).

Thus, IMO the next step is the 24hr bag (or variation like the 72hour bag). So, that's next...
