So I got the uncaptured guide rod kit from wolff for the m&p 45. Guide rod looks great, 14lb spring feels awesome. They also sent a replacement striker spring with each recoil spring. Took my striker apart to switch it out and the stock one was over an inch longer, soooo called them back and turns out they were sending the shorter springs which are for the 9/40/357 with all their kits and basically told me "whoops our bad, tough luck, we sent you the wrong spring but we don't make the other one". Sooo looking for a striker spring for my pistol without dealing with smith, any suggestions?
