Try Tactical Sh*t. I'm not sure of availability, but they did have them in stock the last time I looked a couple of weeks ago. Have you looked at any other manufacturers? I've got a Saurez on my 17 and love it.
I did check there. They don't sell the no back strap option.
I put one on back order with LA police gear.
I want want the agency in particular not for reloading aspect more for the grip aspect. I conceal this gun and the Suarez if just a bit bigger than the agency but it's just enough bigger I don't like it for the purpose I'm looking for. I contacted agency arms they said they are restocking vendors daily over the next few weeks.
I sent a gun to Agency for their full molestation. The hold up on getting the gun back is apparently the magwell. I should have had the gun back, 2 months ago.
