While not explaining why, Glock USA just announced that it will trade your Gen4 recoil spring for an updated version "in order to ensure our products perform up to GLOCK's stringent standards," says the company.

Our guess is that it addresses a well documented issue with Gen4 pistols in which brass is extracted from the chamber, but not properly ejected. I'll see if I can get more details, but for now you can go to Glock's spiffy new website for information on exchanging your spring. Follow the spring exchange link on the lower, right side of the home page. Glock points out that the Gen4 G26/27 recoil spring is fine and is not part of the voluntary replacement program.

From Glock's website:

"GLOCK Inc. is voluntarily exchanging the recoil spring assembly (RSA) on its new Gen4 pistols (with the exception of G26 and G27 models). GLOCK has developed a new design to the recoil spring assemblies on its Gen4 pistols to replace several variations that are functioning in the market today. As part of the company's commitment to perfection, we are voluntarily exchanging the existing RSA in order to ensure our products perform up to GLOCK's stringent standards."

"GLOCK is replacing the RSA in all Gen4s sold before July 22, 2011 at no cost. Please complete the following procedure to receive a new RSA. The RSA can safely and simply be swapped out using normal field stripping protocols. If you have additional questions, please contact GLOCK at 1-877-745-8523 with your serial number and model number."

"CONSUMER ACTION:"
