Thanks for looking and taking the time to respond. I'll likely head down tomorrow to take a look and hopefully vacate some casings while I'm there. I believe the SF to be the same as a size as a Gen4 w/out backstraps. Big fan of the Gen 4 texture though.
The SF is Gen4 and I doubt they will make it in Gen4 especially with the just released 30s. But what do I know? Hard to keep the compacts straight with the 30, 30 Gen4, 30s, 30sf, and 36.
I was in there today and they only had two Glocks in stock--a 17 and a 27 both gen3 (and very reasonably priced). A couple of weeks ago the case was full. The shop guy helping me said they'd sold at least 40 this month and I believe it.
