Product Overview

Keep your Hornady Lock-N-Load AP press running smoothly with the genuine Hornady Primer Slide Spring. This small but critical component is responsible for returning the primer slide consistently and reliably, cycle after cycle, so your priming system stays in time and feeds primers exactly where they need to be.

Built to factory spec as part #392336, this replacement spring is a direct fit for the Lock-N-Load AP automatic priming system – no modification, no guesswork. Swapping out a tired or damaged spring restores positive primer slide movement, reduces misfeeds, and helps maintain the press’s trademark smooth, repeatable operation. Ideal to keep on hand as a spare, it’s a simple, low-cost way to protect your reloading workflow from unexpected downtime and keep your progressive press delivering safe, consistent ammunition.
