They are quite common in IDPA Enhanced Service Pistol Divison.
Since they are mass produced, accuracy and reliability run from great to, well, let's say "improvable."
Mine did very well with only a trigger adjustment on the factory parts and a little work on the barrel's integral ramp to make it a feed ramp. Shot about 10 MOA. That sounds like a lot but is 2.5" at 25 yards, not bad for stock barrel and bushing, and fine for IDPA. I know of one that was refitted and will do that at 50 yards.
Mine has been extensively modified since then, but that was as a project gun not much related to what you get from SA.
