CZ P-01 & 75 Compact come from production without any magwell.
The good news is that there are quite a few compatible magwells [all of them you can find in this category].But it also brings some other required changes that you have to consider before ordering a magwell.
When you decide to get a magwell for your CZ P-01 & CZ 75 Compact, keep in mind that you will also need to get short grips and mag pads that are magwell-compatible.
We explain everything futher below.
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
You will need to do some other changes on your CZ in order to accomodate a magwell:
Once you have short grips installed, you will see that suddenly the pistol grip is ready to accomodate a magwell below the grip. Clean and lubricate the surfaces and slide the magwell in from the rear. Once in the right position, lock it in with the screw.
If you use magazines with the factory mag pads, you will now find out that the magazine cannot be inserted fully - that will be solved by replacing the mag pads for magwell-compatible mag pads.
Once you have the mag pads replaced as well, your CZ is ready to go.
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.
