This puts excessive wear on a gun. the 20 lb spring cures that.

I only put maybe dozen rounds trough it with stock spring. You can tell a difference when you pull slide back.
I haven't shot any hyped .357sig ammo except for some 2007-version of Double Tap that may or may not live up to stated velocity figures, but I do know that every range and premium JHP ammo I've shot after installing the Wolff #20 RSA system is much more manageable than with the stock Glock RSA assembly. I understand that Underwood's published figures are the real deal so if you've moderated the recoil with the #20 spring then we've got another testimonial for the heavier assembly.

It just hasn't made any sense to me why Glock uses a standard 18# spring for 9mm, .40S&W, and .357sig. Instinctively I feel that .40S&W and .357sig should have a heavier spring load than 18# as standard issue.
