Magwells for CZ Scorpion

First of all, why to get a magwell at all.

Do you need a magwell? Probably not. But once you have it on one gun, most probably you will want to have it on all of your guns.

Primarily: it makes the reloading safer and faster. What magwell does it that it makes a larger opening for the magazine insertion. That allows you to reload very quickly without giving even a slight look at your handgun. And thus not loosing the eyesight from the target. 

Secondarily it improves the weight distribution. Magwells are made either of aluminium or of brass. And adding those extra grams of weight [brass is always considerably heavier] to the bottom of handgun changes slightly the weight distribution, and as a consequence improves recoil behaviour of the gun.   

Overall, magwells are used primarily for competitive shooting. Not that better reload and weight distribution shouhld be appreciated only in those uses, but that is where you will see magwell being used the most.
