The rearmost marking looks like a prancing lion or bull - upright on its rear legs with a long tail forming a "S".
The only slide lock is located directly in front of the grip on the left side and it locks into a notch located about 1/2 inch back from the front of the slide.
It is definitely marked Made in Spain on the left side of the slide
