It looks like screws but at the very least it would be a barrel swap from the side feed for the hopper to the bottom feed for the mag, I don't know if that would be practical.
you remind me of a guy in a martial arts class I took once who said the sword he had was too heavy. The teacher looked at him with scorn and said "No, your arm is too weak"
There are plenty of players out there(some so superhumanly strong they carry more than 3 tagmags, I know one guy who packs a dozen
) that are able to do just fine with this supposedly insurmountable handicap, perhaps it's only you.
I use 2 pistols and routinely fire up to 200 rounds in a 15minute game! I've practiced and learned to be able to do it, it simply takes a little more self discipline. You wouldn't know this but though 12grams do taper every shot, they do this consistently, the same way every 12gram so it's only a short time before accuracy returns as you practice. The paintball limits accuracy far more than that.
Like you, I used to think "If I was at one end of the field with a pistol and my clone were at the other with a machine gun, the machine gun would win." and feel that settled it.
I learned later that the real question was "if ten players were at one end of the field with machine guns and at the other end were 9 machine guns and 1 pistol player, who would win?"
Paintball is a team sport and a good pistol player can do things and fit in places that someone with a regular marker cannot, but there's not much to be done with 10 machine guns that you can't do as well with 9, that's the nature of machine guns.
By your logic everyone would settle on one paintgun and everyone would use the 'best gun', in reality a team needs to be versatile to win and keep winning.
I'm the opposite of your ideal, I'm going to buy one of these, break it down into a pistol and never change it from then on, as I like the fact that the body covers the length of the barrel and the 'peephole' which lets you check the breech has been moved from the top to the side. These two things will make it behave much better in the rain than the tag8 which is important in a primary pistol.
Heh-heh, I appreciate your wishes of 'good luck with that' Gamer,
I should say that I haven't been shot in the hopper in 14 YEARS, good luck to YOU with THAT!
