These are wonderful rounds to have in a city neighborhood for personal/home defense. They cycle very well in my Walther P99 .40, providing responsble, routine cleaning and maintenance is conducted (applies to any ammo or any weapon). Got a buddy considering these rounds in a public security roll. Their price does not prove economic for routine or extensive range testing for most individuals.

These will NOT feed reliably in my S&W M&P .40 Compact whatsoever. Tried multiple magazines. Tried several rounds to make sure it wasn't a fluky or damaged. Will not chamber the first round without shaking or manually aligning. Tried normal fast snap I use for every other rounds (Speer, HydraShok, many others). Tried at least 20 times, not a single one chambered on it's own. Don't want to try it by firing a live round and jamming anything. Have had the M&Pc for several months now, about 2000 rounds through it of all descriptions. This is the first one that had any problems, but the problems were doozies. Not recommended for that firearm. Their .38 version works fine in my revolvers, but I wouldn't trust in a semi. Too expensive to test fire sufficiently.

These rounds do what I wanted them to. I tried them in wet phonebooks, (redneck ballistic gel) and they work great. Buy more then one pack though. They feed, and will cycle the slide.
