A quick video showing the two side by side. Shooting review to come later.

Good start Jeff.
Can't wait to see if there is any performance differences. Somehow, though, I sort of doubt there will be.

just sitting here at work so i figured it was as good a time as any to make sure the Tornado threaded barrel fits well in the mk II.

it does.

Barrel is only slightly different in the breech area versus my 2004 USG. May not be any different compared to a newer USG.

Thanks for posting that video, especially regarding the holster. I have a OWB Blade-Tec coming, but it is a tac-light model. Hoping my MKII will fit it. Also have a defensor holster coming soon, and believe it will fit no problem especially since Dennis knows about the measurement differences as I gave them to him when I got the MKII. It was notably tighter in my MTAC. I had to loosen it up also, and really need slightly longer screws TBH for the tension. Decided not to us it in the MTAC.

Shot mine last weekend. Shoots like a FiveseveN, and throws the brass just like the MKI, which is the only thing I do not like about these pistols.

There is only one small difference in the barrel as far as I can tell. Here are some pics from different angles.

The Mk II is on the left and the USG is on the right:

Is the left front top corner of the magazine well different or is that just the way the light is reflecting off it?

Thanks for the great pictures.

From them, I can see several differences in the lowers.

I'm not sure if they affect anything if you swap uppers and they shoot.

I shot it for the first time today (sorry no video this outing) and shocking, it shoots like a... Five-seveN!

I put 200 rounds through it, 100 SS197 and 100 AE. I didn't touch the adjustable sights and at 7 yards the SS197 shot low/left about 1" and the AE shot about 1" low. I didn't bring any EA ammo to play with this time - S4M is what the Mk II will be zeroed with eventually.

Maybe it's because I'm used to my accurized FsN, but it seemed that the new baby launches the brass even farther. I couldn't quit tell because I was at an indoor range, about 12 feet from the wall, and the cases were hitting the wall pretty hard and bouncing back towards the middle.

Group sizes were about 1" at 7 yards and about 4" at 25 yards. It probably should have been better at 25 yards, but my eyes were even worse than usual and I had to keep focusing on the same blurry spot, haha. I also shot the Tavor at 25 yards with magnification and made one neat little ragged hole. Getting old definitely has its drawbacks!

One more thing - after 200 rounds, the FsN Mk II barely needed any cleaning at all. MY USG doesn't exactly get filthy after 200 rounds, but there is at least some fouling.

just picked up my MKII today in FDE, I read somewhere else that the current sight mounts for the USG models MAY not fit the MKII? can anyone confirm this? I almost bought my burriss set up today, glad I found this forum!

I tried putting the USG slide on the Mk II. It fit, however when I pulled the trigger (dry firing), it jammed. I couldn't pull the slide back and it only freed up when I dropped the mag. Right after that I could see the barrel kind of jiggling around in the slide.

I would try it again and video it so you could see, but I sent the Mk II off to Jay so he can break it down and take hi-res pics.

Now the barrels... that's the real question. Putting the USG, or EA's Tornado threaded barrel in the Mk II seems to work fine when dry firing. I was going to put some rounds through it until I noticed that there is a small notch cut out of the Mk II's barrel, where the USG is solid. You can see what I am referring to in the pics above... I'm not sure how that will affect the functionality and am not brave enough to just try it.

My burris mount will not fit on my MKII... At least without butchering the slide cover. TBH, I have not pulled the slide cover off to find out either, as I am using it as an excuse to keep my USG!

ETA: I swapped my slides and both dry fired fine. However, I will no be live fire testing...

They are not interchangeable. The area where the take down cam engages the slide has a different contour due to the one piece slide.

I'm sure they felt that they had to change it just enough so that bozos couldn't take peices parts from one and put it on the other to create a bastardized version of either.
Some enterprising young up-n-comer will create a 'conversion kit' though and make it possible to interchange anything you want.
Some day.

They have beefed up the frame in a whole bunch of places. To do this without changing external dimensions massively they needed to tweak things in the inside to clear the added material. Some parts can swap but only in one direction.

So is the MKII "better"? My dad has a MKII and I have a USG, and we got them both about two weeks ago. Neither of us have had a lot of time to get to use them yet. Personally I like the looks of the slide better on the USG. That being said, if the beefier frame of the MKII or any other aspect of it makes it "better" than the USG I would like to know so I could sell it and get a MKII while I still know where there is one at.

Better is a rather subjective term.
The FsN was a well designed weapon in the first place. Although there really isn't that much room for improvement, they improved on the few things that they COULD (from what I understand). Although there are improvements, there's nothing wrong with the Mk1. You didn't do wrong by getting it.

I don't care about aesthetics when compared to function; in firearms.

The USG does look better. The MKII would get my vote if I had to choose, as it is more robust, on paper.

However, that's just paper.

The gun has not been out even close to long enough to identify any potential flaws it has in the updated design.

Not even close.

I'm going to be the match director for the TXST Night matches. I plan on designing really challenging stages and bringing the FsN to shoot. I know my USG broke the taclights and MRDs mounted on it; I wonder what the MkII will do.

I wonder if the MkII frame is sturdy enough to handle a brass catcher mounted to the rail? I know the MkI had issues with that but maybe they fixed it?

Anyone want to volunteer their MkII for destructive testing? :laugh:

-Jay

Hello all, first time poster, long standing fan/supporter/reader/student. I have a question primarily for Jay, but I will also appreciate any observational thoughts from any others. My question is this, do you feel that with the increase in frame thickness in the MK2, that any mechanical parts were negatively compromised to accommodate the needed space? For example, mechanical parts either shrunken in size, or not seated/ anchored as well as in the MK1?? I am interested in even the slightest amount of change in dimension, but primarily upon parts you feel could foreseeably decrease the firearms longevity or cause parts to break. thank you for your insight/expertise.
Sincerely, Chase.
