It was a Glock 19 with nearly identical construction to the real thing. But I checked, the chamber is fully supported on this one.
One of the instructors from my dojang holds a force-on-force class once a month at the dojang. Takeaways, retention, using cover . . . supposedly we are going to cover all of the windows with mattresses to black out the place and practice identifying targets in the dark with lights. There will also be wrestling for those of us who have ground fighting experience. Should be fun.
By the way, I went to Airsoft Atlanta today to get the pistol. Neat store - they had a lot of really nice "tactical" gear and even some spare parts for a P90 rail system that no one can find on the internet right now. What was a bit disturbing (other than the grown men squealing at the G18 airsofts and buying 2 for a dual SOB holster setup) was all of the kids running around grabbing the dozens of display guns and dry firing all over the place.
Now I had just come from the range and there were plenty of parents with their youngins' teaching them to shoot responsibly. And here I was looking at adults bringing their kids just five miles down the road from the range to a toy gun shop and letting them get all kinds of bad ideas about guns into their heads. There was a pistol gripped shotgun airsoft that a little kid picked up, sighted with his eye right in front of the optic, and pulled the trigger. Now this is airsoft and nothing happened. But I see this same kid four or five years from now picking up some friend's pistol gripped shotty and terraforming his nose because of some stupid behavior he picked up while his dad was drooling over a $650 AK airsoft that looked like it was fucked in the ass by the TAPCO-Fairy.
Oh, and the $2500 Barrett .50 Cal "sniper rifle." Christ! Just get the real thing if your wallet is that expansive!
