I took a handgun in to have fixed a couple of weeks ago. It had a spring that had broke and would not allow you to cock it and advance the cylinder. The guy that I took it to didn't have one like it to replace it with, so he had to special order it. That dang little spring cost more than $4 & the shipping (UPS) for that little sucker was $11. Not to mention the labor for him to fix it. But I got it fixed and got it back so that is the main thing.
