Maybe so, which is why i wont take their advice, they use what they have found works for them and gives them the best performance for how much they shoot.
For the weekend shooter thats not advice that should be followed as most modern pistols will outshoot the average shooter, so why limit options due to what vickers or any of those other guys say. Find what fits your hand the best weather it be cz, glock, sig, mp,beretta etc.. All good guns. Buy one have fun shooting it and dont worry about what vickers says as most on here will probably never reach that level.
