I have the Beretta practice kit, unlike the Ceiner product it does have the slide mounted safety/decocker. I use CCI standard velocity ammo, accuracy is acceptable, not as good as my fathers S&W 617 for example, but a useful training aid and great for cheap plinking. I get the occasional light strike in single action (I have a reduced power hammer spring fitted) but it always goes bang in double action and never fails to cycle or eject.
The magazine loading device is needed, otherwise you may cut your fingers trying to compress the spring. I give it two thumbs up, I put more ammo through it these days than all my centerfires combined.
