Oldbear, the 1377 is a pretty awesome gun for the money, but for 10m shooting I think you would definitely enjoy something more focused on that task: better grip ergonomics, sights, trigger, and no need for multiple pumps, etc.
The V10 is a good pistol; I had one years ago (when it was known as the Gamo Compact). I had to whittle the grips a little for my smallish hands, it's rather muzzle-light in balance, and its construction has a lot of plastic, but basically it's a good gun. Looking at Pyramyd's video, perhaps the trigger has been improved a bit over the early one I had too.
IMHO the best self-contained intro-level match air pistol of the last few years is the IZH 46 and 46M. Unfortunately those have gotten quite pricey, but you might keep an eye out for a good used one. Another gun I like is the HW 75 (aka Beeman P2); the layout of it is not truly that of a "match" level pistol I guess, and again they are expensive, but the thing is very accurate, has a great trigger, is built solid as a brick, and just kinda sings to me.
You might even like the Beeman P17 better than the 1377. Those are so ridiculously inexpensive that there's little reason not to try it - really every air gunner should just own one anyhow!
