Hard to generalize, depending upon use, Caliber and ammo used, Gun Manufacturer, and Spring Manufacturer.

For 9mm, in the past it has generally been recommended between 8,000 and 12,000 rounds.(S&W)

Beretta recommends Recoil Spring replacement for the M9 at or before 15,000 rounds and I would assume that the same would apply to the Taurus PT92 or most any other 9mm pistol.

I had put about 15,000 rounds thru my PT92 before replacement of it's Recoil and Firing Pin Spring. Could feel the frame being battered at this point even though the PT92 still cycled well. Then I replaced it with an extra power 15 lb Wolff Recoil Spring (Factory Standard is 13 lb.s) which in theory should last even longer.

For .45 ACP chambered handguns, most serious Match and IPSC shooters are replacing their Recoil Springs at or near 8,000 rounds. Even though at this point the Springs may still be serviceable, in theory, the fresh springs will keep wear and tear from the frame. I had gone 12,000 rounds on my older EAA .45 Witnesses original recoil spring, and as with the PT92, even though the Recoil Spring was still functional, I could again feel both the handgun frame and myself taking more of a battering.

For Taurus 24/7 Pistols, I would not expect Recoil Spring maintenance practices to be any different than any other handguns.

MPanova - Glad to hear your long term test of a .45 PT24/7 is going so well!

Excerpt from the Wolff Gunsprings FAQ:

4. How often should I change my springs?

Wolff Gunsprings are made with the highest grade materials and workmanship. Most Wolff [recoil] springs will remain stable for many thousands of rounds. The performance of your gun is the best indicator of when a spring needs to be replaced. Factors such as increasing ejection distance, improper ejection and/or breaching, lighter hammer indents on primers, misfires, poor cartridge feeding from magazines, frequent jams, stove pipes and other malfunctions are all possible indications of fatigued springs or improper springs. Springs that are subject to higher stress applications such as magazine springs, striker springs and recoil springs will require more frequent replacement than other less stressed springs. Most Wolff recoil springs should be capable of 3000-5000 rounds minimum before changing is required. Some recoil springs in compact pistols, especially where dual springs are replaced by a single spring may require changing after 750 - 1500 rounds. Changes in your firearm's performance are one of the best indicators that a change is needed.
