You have made a statement, and then ask us to justify your statement? No. While Glock makes a good handgun, there is no ONE make of gun that is "the best" for everything.
Glock is the company which makes them.
Glocks are *usually* black in color and have a very "boxy" appearance. They have no visible hammer or safety. Their sights are usually raised box sights. They can have barrels ranging from 3" to 5" and grips ranging from two finger grips (trigger plus two fingers) to full grips. Stock Glocks will have either no finger grooves or only one small finger grooves. Glocks are always handguns unless they have been modified by the user. Beretta makes handguns, shotguns, and rifles. Berettas can look like almost anything.
I would say that converting your Sigma 40 to 357 SIG would be straightforward however I doubt if the Glock barrel would drop in. I suggest that you contact Barstow. If anyone makes the barrel you want, it's them.
Midway USA makes one which the company states will hold all 10mm and .45 ACP Glock magazines. Glock themselves also market a mag holder (Model MP03080). Doing a search on Google should help you find these, as URLs cannot be posted here.
It's strictly a matter of opinion. Glock makes a very reliable mid-priced gun. They are hard to beat for the price.
There isn't much in it, however i would always go with glock, however you should consider sig sauer as well.
its a man who makes a market
