The OP return springs for the Walther polymer-framed striker-fired pistols reduces trigger pull and break on an already incredible factory trigger. Made in the USA of high-tensile music wire, this proprietary spring will drop your break by up to 1lb (red) and 1/2LB (green).  Included in our trigger kits for Walther, grab a few extra for the range bag or upgrade your existing blaster. As always, it is covered by Overwatch's lifetime warranty and fits the PPQ, Q4 TAC, Q4/Q5 SF, and the new PDP series of Walther pistols.
