Supposedly the 43x and 48 are offered overseas with rails, unless it was fake news.
I have one of each. I bought the 48 lightly used and it had a minor issue with the mag catch, it was deformed and would catch on frame. I bent it a bit and it seems work. I bought 2 of the SDI 15rd mags and they have been 100% for about 100 rounds each. I replaced the 43x mag catch with a Hyve? from Epay and it is a nice piece. The SDI catch was out of stock, it was my first choice. I and my friend that was with me tended to shoot both examples left for some reason.
I plan to put it on paper and see what I get soon.
The 43x and 48 are offered with a light rail in Europe, but the placement of the serial number makes it impossible in the US versions unless they move that plate. In Europe, mostly, they serialize the barrel and slide, not the frame. I've seen Glocks in Austria at least with no serial numbers on the frame. That's the norm.
