Recently I was given a barely used Kimber 1911 target pistol in 22 rimfire. Not a gun I really need but hard to resist a freebie.
At first I was horrified by the 5 1/2 pound trigger pull, but then relieved to read in the manual "dry firing will not damage the gun". So, off I went, adjusting springs to bring the trigger pull down. This involved quite a bit of dry firing but I wasn't worried. After all, "dry firing will not damage the gun".
After about 100 rounds of live firing the gun at the range, the gun started to jam when feeding. I found that the dry firing had peened the top of the breech. There was a small nick and a burr which the projectile was catching on as it fed into the chamber and was causing it to jam.
So much for, "dry firing will not damage the gun".
I fixed the feeding problem by polishing the burr off the breech and the gun operates well at the moment.
My problem is that, as is normal with this model gun, the slide doesn't lock back after the last round has been fired, so unless you carefully count the number of rounds fired, you end up dry firing every time after the last shot. This must cause the same problem in the future.
I have googled this issue, and it seems that some people have the same problem as me, while others claim to have dry fired thousands of times without problem.
Suggested fixes are: carefully remove metal from the top of the breech so that the firing pin no longer hits metal, or: grind several thou off the firing pin for the same result.
Anyone had similar issues? Suggestions?
