Colt Diamondback 22cal. misfires only when firing double action. Single action ok. I replaced main spring but still experince same problem.Is it possible to bend main spring in a way to apply more force to hammer?
Thanks in advance

Before doing anything else, change brands of ammo, and scrub the chambers out throughly.
Test fire again.

UNLESS there is another problem, like a worn firing pin, you can add more tension to the mainspring by carefully bending the upper leg slightly.

However, if you bought a new mainspring, and it's still misfiring, there's likely another problem.

If it's still misfiring, I'd suggest sending it in for a repair, since a new mainspring SHOULD have corrected any spring related problems.

I agree with the ammunition change. You could also flush the action with brake cleaner spray. reoil and try again. If you still have misfires or light primer strikes, find a Colt gunsmith.

Spend $5 on some quality target ammo. If the Diamondback misfires, then it's the gun.
