I' ve been using a Wolff 18 lb recoil spring in a Taurus PT 99 for some years now. In an attempt to further reduce frame battering and muzzle rise I' ve purchased some shok buffs from Brownells. However, after installation the slide will not lock open manually. Is the compressed length of the Wolff springs greater than the factory 13 lb one. I no longer have the original to compare with. Can anyone help?
NOTE: Brownells catalog listed the item as for the Beretta 92 but said it would work on Taurus as well. Slight dimensional differences perhaps?
