In my mind fit is a much larger factor with pistols than it is with rifles since more shooting is done offhand and proper grip is easier to maintain when it's comfortable and not forced.
Go to a gun shop and hold some guns, and ask if you can dry fire them to get a feel for how the trigger reach is (both SA and DA if applicable). Don't be put off by a heavier trigger unless the pull is inconsistent or overly gritty.
To highlight this I'll mention Glocks. I personally shoot very well with a full size 9mm Glock, but my natural grip causes slide bite and my middle finger knuckle hits the trigger guard. I would have to modify the frame to improve this and won't buy one until I find a melt job that fits comfortably.
On the other hand Sig, M&P, FNP/FNX and 1911s all fit very well out of the box and simple tweaks like thicker grips is all I need.
Unlike a rifle, pistol skills tend to take quite a while to get down. Since the gun is only in your two hands it takes quite a while to be able to shoot accurately, especially at longer distances. I had a Sig 229 .40 that I shot around 3,000 rounds with, and when shooting at speed I always pulled right from a grip/trigger pull issue. If I slowed down I could nail the bull.
If you want a Striker gun the Glock, XD, and M&P are all great, and they all fit differently, and now all come with grip panels (Gen 4 Glock and XDM).
If you want a DA/SA, the Sig, Beretta 92/96, HK, CZ, and FNP/FNX pistols are all great.
If you want SAO, the 1911 is a big winner, and companies like Sig, HK, and CZ make variants that are SAO.
Lots of choices to look through.
