Wolfs site only has the springs for the 9mm, 357, and 40. Every site ive been to says they are not for use in the 45ACP. I have to send the pistol in to Springfield to replace the Locking Block anyway, so ill just have them replace it. I just think its odd nobody has it. Shouldn't have to go to the factory for a wear part in a newer pistol. No big deal now, but if anyone finds a dealer that has them let me know. Thank you for the help.
