I've just gifted a 350P in .177 to my son. And believe me , I've got hooked to it! Amazing air gun to handle, and behaves just as you wish to. I've been shooting similar groups at 100 feet with the open fibre optic sights, that too off hand!
BTW, where did you get the 38 joules and 1050 fps in .22 figures? Unless you have modded or tuned it.
With the .177 I don't think it's more than 21-23 joules and 800-900 fps despite what the manufacturer and the general public says. If you use lighter pellets of 5 to 7 grains you might get those velocity figures but at the cost of accuracy. I have been using Crosman premiers and JSB Heavy Exacts at 10.54 grains. Performance is really good with these heavies.
Maybe one day I'll chrony it and get the exact figures.
As an aside, have you been living in Europe and moved to Bangalore recently?
