I don't think you get it. Hunting is the closest you can get to combat with out going to combat. There is nothing on a square range that can equal a live target. Even the lowly jack rabbit is a better adversary than a paper silhouette.
I spent many days walking the desert shooting jacks, grouse and other targets of opportunity. I have hunted and taken big game with a pistol. I have learned a lot from doing those things, something I wish I had done before I went to actual combat. You see, when you have something that is alive and a will to live, they tent to not sit still. This creates different and challenging variables such as but not limited to, moving targets, targets of unknown distance, targets behind cover/concealment, etc. Some of them will even defend themselves. I haven't had to shoot a charging boar or bear, yet. Then there is the shooter side of things, surprise, buck fever/adrenaline rush, unstable footing, improper grip/shooting stance, etc.
Pistol vs revolver, the only thing I have here is, you do include magazines in with parts for a pistol right? I don't think a Glock would go 25k without some type of PMCS especially when you include mags as part of it.
