Just got this today and I'm having a blast with it. It has an automatic reset trigger so you don't have to rack the slide every time you pull the trigger. Straight out of the box the trigger felt much stiffer than a standard Glock trigger, but after a little polishing it feels about right now. It has a standard 9mm barrel so it will chamber dummy rounds along with live rounds however the firing pin is cut down and there is no hole in the breach face. So essentially it is a non-firing, fully manipulating Glock. It makes it very easy to do rapid reload drills with loaded magazines along with dry firing the crap out of it. This will make a great training tool. Anyone else have experience with these?
