Assuming a BG is at my daughter's bedroom door and I am at mine, the shot is about 30'. I'm not going to shoot and take a chance of missing and hitting my daughter, so I would need to aim a bit.
For very close range, no sights are needed...so should we all buy guns without any sights at all?
Also, I don't buy the 'gotta be first to shoot' mentality. If you shoot a BG in the heart with a 44, there is still enough blood & oxygen left in the brain for him to shoot back for 10-15 seconds. If you are serious about stopping him, the extra 2 seconds to make a head shot may be more effective than shooting him in the chest and having him shoot back for the next 10+ seconds...
Same if he is holding someone. A shot to the head will stop him...so I want the OPTION of trying for an aimed shot, knowing that if it all happens at 5 feet, the sights won't be needed.
