1911 front sights can be broken into two types Stake in, and Dovetail.
Lets start with the stake in sights. Most 1911 fans have seen these at one time or another. This type of sight is standard on GI models as well as a lot of Colt and Springfield models. It was also the the original front sight on the platform. Pro and Con time.
1911 GI’s are very affordable for many reasons the stake on front sight is one.
In truth all the pro’s and Con’s are from an installation stand point and Stake in is just as usable as Dove tails.
Most gunsmiths don’t like dealing with stake in because of the time they take.
There are a few different dimensions from model and manufacture.
Depending on who the sight manufacturer is it might need special tools.
Stake in have a tendency to come loose and wobble.
Dovetail is what most of the market is using these day’s. Install wise they only require a punch and mallet, so there are a bit easier to install. If you were to ask me what kind of front sight i prefer this would be it, i have just never been a fan of stake in.
Adjustable, this minimizes the risk of a manufacturer defect in sight placement.
Verity, as this is the most common installation method, so these sights come in every shape, size, color and creed.
Adjustable, being that the sight is adjustable everyone thinks that the gun not hitting where they are aiming is the sight being off. Harsh reality time, most of the time is the shooter not the sights. please stop trying to hit your site over with your pocket knife.
