I respectfully disagree with Daisy and James.
If you train you can focus on the front sight, and have first round hits on your target.
A few years ago in NYC, some guy walked into his work place and shot his boss in broad daylight. I believe it was in the morning.
Two cops responded to the incident, tracked the guy down. He went to pull his hand gun, they drew and fired multiple rounds. They hit and killed the shooter. AND they also hit 9 bystanders, because they were focusing on the shooter and not the front sight post.
As for training, I use a pellet pistol to reduce my costs, and trips to a range are not required. I shoot across my bedroom into a pellet trap.

Others have blowback or the action will faux cycle, forcing the shooter to have to re-sight-in on the target. Many are officially licensed by the arms manufacture to be identical in size of the real firearm to fit in your holster for practice in drawing.
