I've not shot my pistol with the product yet, but the machining looks very clean. my pietta threads didn't appear to be machined all the way 100% accurate, so some of the nipples felt like they were tight but in fact needed to be further tightened, i had an issue with the cylinder rotating because they didn't seat far enough, this isn't an issue with the nipples, just an FYI with pietta. Now that they are corrected seated, revolver cycles fine. cannot wait to shoot it. cci #10 and #11 appear to fit ok, once i shoot i can tell which ones stay and which fall off.

A must have for any C&B fan. Fast shipping.

I've two sets of these now. They help with the broken caps falling in the action. The fact that they are stainless let me know when I've got them clean after shooting. Big improvement over stock.
