I will start by saying that I do not play airsoft. I am looking for a GBB pistol to use in my home for training. I own a full size Glock handgun, and am looking for the most realistic airsoft gun to train on. I have heard that TM is the best, but I cannot find one with a metal slide. I need it to be as close to the real steal as possible. I have seen that WE comes with a metal slide, but I have consistently seen that TM gets higher rating. What would you recommend considering you have more experience than I do in this matter.
