If it's only ten years old, it wouldn't be a 70 Series, since they stopped production circa 1983. On the other hand, if it says Series 70 and doesn't have that infernal POS plunger in the slide, then it's older than 10 years. Is the feed ramp unmolested? The original ones were blued. I just bought an old Series 70 lately that had its feed ramp and bbl butchered by some idiot. Hopefully I can fix the ramp. If your gun is solid, you have a good candidate for any work you choose.
