Ooooh, hell! I just have to weigh in on this 'what's the best pistol?' thing. There is no best! I can shoot ANY handgun I pick up well so long as it is not overdue for the scrap bin. And the same with any other tool. You don't buy custom hammers, pliers, handsaws, screwdrivers, shovels, picks, chisels, can openers, scissors, etc. Instead you adapt yourself to the tool! Same damned thing with guns! If you'll simply learn how to properly grip ANY pistol or revolver, obtain a sight picture, and squeeze the trigger, then ANY of them will shoot well for you!
My $00.02 and I'm sticking with it. Get off the this and that make, model, caliber, grip style, and so on. Please! Learn practical shooting and 'custom' choices become moot. I have more than 30 handguns from 22s through 45-70s and I'm damed good with ALL of them. NONE have custom grips or anything else 'custom.' A number have adjustable sights but other than elevation for extreme long range, all are centered for windage. And don't give me crap about I have to adjust the windage because of my eyesight. Ain't so! We all see the same. If we didn't, we wouldn't be able to drive cars. People with rear sights screwed way one direction or the other are 'milking' the gun and haven't learned to shoot.
