Owned (& sold) most Webley pistols over the years, have some modern CO2 pistols. Still have a few of the old Wobbleys. Last to go would be an early Hurricane .22 which I've had for 20-30 years or a mid '60's Premier. The modern CO2's, Wesson, Crosman & Umarex - just feel no attachment to.
As for why? Guess because the Webleys are what I grew up with.
