Title says it all. I installed a 21# mainspring and no joy.
On ftf I can recock hammer and it will usually fire the 2nd time.

Today I took a small plastic mallet and whacked the rear of the slide 2-3 times before pulling the trigger and they all fired this time.

My next thought is to get heavier recoil spring. Is there something else I should be looking at???

Thanks
