Very useful information Iain. I recently recently bought the Buck Mark (at the prices from Europe it would be rude not to). The trigger was so heavy I thought the safety was still on

I bought a spring off the bay having virtually the same characteristics as the original trigger spring, cut it to the same length, then clipped a little bit off. The result was a lighter, more manageable trigger, but still safe (with the knock test). Although not the lightest trigger, for such a simple mechanism it is surprising consistent and relatively creep free.

My pistol is running at an average of 310 fps with Hobby or Geco; but it is considerably more consistent with Hobby.

It is a ridiculously easy pistol to cock (working around the front sight), and very smooth at that, which makes it a pleasurable plinker. I find the safety is very well positioned for a right hander.
