I don't think they are nervous, glock released the g43 after the shield, they are just trying to compete with the market like everybody else. I hope they release a great gun without the stupid grip zone, and better than the XDS. Probably a 380 ?? Maybe they are anticipating to the new shield 2 or BDG 2 ??
I have owned several SA guns, liked some better than others, but never had any issues with any, anyway just two more days to find out !!!
