So as the title says, I need a CCW holster for the Sig Ultra compact 9mm.
I have several Galco holsters for other guns, but I emailed them and they told me they do not make any holsters for that gun due to the oversized contoured side, to use their words.
I prefer leather, but I did call crossbreed and the do make them for that gun. I wanted to see if I could carry it at the appendix but not sure if it is too large for that.

I have a Springfield EMP9 which is very similar to your Sig Ultra.

I currently use IWB from Nightingale:

When I still carried OWB, I used R Grizzle:

Both are quality leather holsters. They're a wait with Nightingale being 28 weeks and R Grizzle being 15 weeks but well worth it.

I have Never carried IWB, not sure about comfort level.

I kinda wanted to carry it at the appendix position.

I will check these out.Thanks.

both look very nice, but I would like to have it a little sooner than either can supply.
I see the one is in Ohio, not sure where Medina is, probably near Cleveland, since I do not get up that way much.

So, I emailed the Nightingale and he is very pricey and is about 28 solid weeks out.

I did email Tucker and they are a ways out, but not nearly as bad. A little easier on price, so I ordered my holster, belt and mag pouch tonight.

I went to a ton of websites. I liked a lot of holsters, but wanted to match a belt and mag pouch. Some sights did not match those.
But anyway, I am now waiting for my holster and matching items.

Try https://www.craftholsters.com/
they deal with custom holsters

Went with the Tucker and got it.
Got the belt, holster and mag carrier.

It is tight and very hard to get on, but the quality seems first rate and it looks very good.

I just wish the buckle had a roller on it.
Once you get it on a pair of pants, I do not want to take it off, lots of work.
