folks, happy new year! I'm having a bit of an issue here. I had detailed strip the trigger assembly for detailed cleaning. I'm just having a hard time putting back the hammer spring. I noticed for the A1, it has 2 springs. There's a 2nd small one meshed inside the other larger diameter spring. I just find it difficult to compress the spring with a big punch as it extends around 6~8mm at the rear even before compressing it. But on the 500 models in youtube I've seen, there's only 1 hammer spring and it doesn't stick out of the housing even before putting the spring pin in. Looking for your advices. TIA.
