Fit is okay - with some reservations - Anarchy Outdoors CZ-P10c Magwell

The instructions link takes you to their support page - but there are no instructions for this item. I did a Google search and found a guy from CZ parts doing an installation video which while not complete (not what size of punch to use, off camera manipulation), was still helpful. For the 10C (different than the 10F), you do need to take out the roll pin and remove the backstrap. I have the medium on mine - there's no restriction listed on which one this will fit on.

You press fit the magwell into the backstrap, then apply the anchor screw (no torque instructions given) and though this is actually a metal one (aluminum) there's no listing for locktite and the screw does not contain it like most do these days, then just slide the backstrap back on and re-insert the roll pin. The bottom edges of the magwell are barely rounded - they feel a bit sharp. I've not had the chance to shoot it yet and see if it abrades my skin. I run this 10C (ported) as an EDC and it wants to grab the fanny pack a bit upon withdrawal - will see if I become comfortable with that. I just have to draw the zipper opening all the way, not part way to get past this 'edge drag' as I withdraw the weapon.. it does feel comfortable to hold two handed.

The fit is adequate. It does NOT grab the front lip of the grip, like most magwells do and there are gaps around the grip once installed - no super noticeable, but there. The finish on the magwell is average, not really even on both sides where it contacts the grip. You have to kind of 'press fit' the backstrap into the magwell - it's a tight fit and starting at an angle helps. Also the screw sticks out of the backstrap at a bit of an angle - not flush fit. They didn't think this through when they decided the angle to tap the magwell for the screw very well.

That all said, once installed all the OEM magazines I have fit and function fine - however you can no longer use a 17rnd mag with a sleeve to clean it up to meet the grip. The 15 and 17 round magazines, as they come, all fit and function fine.

I gave this a 3 star as the lack of lip over the front of the grip, the average at best milling (not equal on both sides) creating some small gaps, the retention screw angle is wonky and they do not provide instructions - but knowing all that and for the price, I still recommend a buy.
