Hey it's me again regarding that thing I don't know anything about. The weapon in question is fictional, but let's say it's identical to the H&K UMP submachine gun, chambered in .45 calibre. I've been trying to understand the reloading process based on its features. So far, according t0 videos and Wiki, its features are as follows: It uses a closed bolt system instead of an open one. The bolt is automatically held open when the last round in the chamber is fired (mag and chamber emptied). It also has a bolt release, which allows the held-open bolt to return to its closed ready-to-fire position without the user having to operate the charging handle. Blowback repeating action Question A After I have just emptied the magazine and chamber, my reloading process would be: 1. Activate magazine release 2. Replace magazine 3. Activate bolt release Ready to fire If I wanted to replace a magazine when I still have a chambered round, I'm assuming this means that my process would be abbreviated, because the magazine can be released independently... I think: 1. Activate magazine release 2. Replace magazine Ready to fire Are these assumptions correct? Question B The only times the user needs to manually operate the charging handle would be: 1. Cycle the action, ejecting a round from the chamber (I'm not even sure if the charging handle does that). 2. If for whatever reason the bolt is in the closed position without a chambered round, or for any other reason the user will need to open the bolt without firing a round. Are these correct? Question C When the chamber is empty and the bolt is held open, would there be any feedback at all upon pulling the trigger? Or would it just feel like the trigger does nothing? In contrast, I'm thinking that pulling the trigger while the bolt is closed and chamber empty would result in feeling/hearing the action dry-fire. And, I suppose that's repeatable, as in, click click click, since it's blowback operated but there's no blowback on a dry fire. Is that correct? Question D Unfortunately this thing seems so user-friendly that it's hard to imagine many errors occurring during loading the weapon. In one scene, a nervous novice will be reloading it with shaking hands, then passing it to someone experienced who then fires it. Can anyone think of mistakes the novice could make that would be at least some form of detriment to the experienced user? Someone might forget to hit the bolt release, but I think the person firing it should be the one to do that after it's been handed to them. As always, thanks for any and all help. I should also probably consider finding a gun enthusiast forum too if these questions are getting out of hand.
Question A your Correct Question B its alway's good to check check and double check some more just to make sure there aren't any live round's in the mag or chamber Correct Quest C 1. No, it does nothing 2 correct if the experienced shooter see's the novice nervous and shaking he/she should IMMEDIATLY take the firearm away. telling them to engage the safety and place it somewhere safe with the barrel aimed down range. so the fail would be experienced shooter. for not feeling the novice first out and starting them with a higher caliber weapon
