CZ TS 2  models [CZ TS 2, CZ TS 2 Racing Green, CZ TS 2 Deep Bronze & CZ TS 2 Orange] do come from production with magwell. 

That however does not mean that you cannot get another one. Compared to another CZ models that do not come with magwell from production, with TS 2 you do not need to replace any other parts except of the magwell itself.  

Why magwell

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.  

How to install  a magwell

With CZ TS 2 the magwell installation is very easy. You just loosen the screw that is in the magwell already, push it from the grip, clean the surface and slide in the new magwell. 

Your factory grips and factory mag pads are already magwell compatible, so no need to change any of that.  

Materials to consider

There are basically just 2 materials to consider: aluminium and brass. If you want to add more weight to your CZ and thus make your CZ better to handle the recoil, get a brass magwell.

Otherwise we recommend going for the aluminium magwell, as it will not increase the weight so much.
