If you don't have access to a good gunsmith locally, don't want to pay one, or don't want to ship the pistol, you might just work on it yourself because it really isn't that difficult to strip and reassemble the frame.
By all means, if you were considering the SRT kit go ahead and order one. At the same time, I would go ahead and order a new sear spring and trigger bar spring.
The SRT kit is basically a new sear and safety lever so you will be replacing the sear, which could conceivably be part of the problem. Give all the parts a good cleaning and examination. Pull the hammer and clean and examine closely the hammer hooks as well.
Ferrari Steve on youtube has some good videos on upgrading a P226 that include installing the SRT and replacing the trigger. Those videos would guide you through the disassembly and reassembly process.
Good luck.
