I'm a sig fan. (I have P230, P229, P2340, P226, and a P220 Sport) Only because they fit my paws.
The Glocks are great guns but do not fit me and I just can not shoot them well at steel or IDPA shoots.
Here is how I can tell if a gun fits me. And it works for most people.
Go to the store pick up the gun in your two handed grip. Finger off the trigger.
Pick a spot out on the wall.
CLOSE YOUR EYES. Yes Close your eyes.
Raise the gun to where the spot on the wall is and settle the gun there, mentally picturing the sights.
Now Open your eyes.
Are you looking down the sights? Are you close to the spot on the wall?
With the Sigs P226 I look down the sights.
With the Glock I see the top of the slide and I have to roll my hands down to get the sights on target. The striker guns always have me pulling to the right, even dry firing.
The up side to the glock is the trigger is the same every time. The Sig has a lighter second shot and the hammer can be cocked for a longer range shot.
But either would be a good choice.
