Santai,
Backwoods was just in front (towards the front door) of the Gunner's Alley table. Right next to the restrooms. The S-series steyrs are unusual. They look to be a bit wider than Glock and also more blocky towards the front, so closely fitted Glock holsters probably won't work. I'll venture that he meant that he didn't have anything that could be adapted to your gun. For instance, I bought a Beretta 9000s Saturday and immediately went to him for a holster, he said he could make it if I brought the gun by the shop or I could try a Sig P239 holster - works wonderfully, the grip frame is essentially the same. I'm really partial to his clip-on IWB. To compound your problem, I don't think there have been any molds available to fit S-series Steyrs. Short answer is, you'll have to let him have the gun for about 2 weeks for him to make the holster from scratch. This is an estimated time, he does get backed up occasionally and I can in no way speak for him as far a manufacture time (this is just what he's told me in the past). He may even be able to turn it around faster. He can custom make it to just about any gun you have, but most people won't want to leave their gun (I can understand that). So alot of time (probably most) the discussion ends there. He may not want to take on custom work at the show (somebody elses gun would be just one more thing to pack up and would be an added liability for him). If you bring your gun to his shop, you should be in business. I'll post the contact info I have (in case you didn't pick up one of his cards) in the next day or so.
Alot of us are wait and see on the Steyrs. I love my M-series 9mm and would like to have an S-series, but I want to make sure the support is there. Holstermakers will be the same way. A good many will be reluctant to stock holsters for a new gun design and will only make to order. I don't know if Backwoods makes one for the M-series guns. If he does, maybe the same mold will work and he can just shorten the holster when he makes it.
