I was cleaning my SA Loaded 1911 this evening and when I checked the firing pin I saw the spring had broken in half. I am not sure when, or even if, the firing pin spring had last been changed. I do change the recoil spring- 16.5#, about every 5000 rounds. I use this exclusively for competition and shoot a load of a 200gr LSWC over 4,5gr of WST. When I checked my parts bin I saw I had several Wolff Extra Power firing pin springs, and one single reduced power spring. I installed the reduced power spring rather than the extra power. Is this going to cause any problems? What is the logic for extra power or reduced power firing pin springs rather that the standard power spring? |
| the other side of Gregory K's comment... a heavy firing pin spring if you use a heavy recoil spring that increases the inertia speed of the forward moving slide, as to not allow the firing pin to strike the primer... I used a heavier than most spring at 22# which would take a permanent set to around 18#, and shot a pretty much duplicate WST load for USPSA... |

I guess I could use the extra power spring until I can get a standard spring. I just had these on hand. |
