Why have the breech forward on a PCC?

[Flashpoint]

I've had 6 different brands/styles of PCC and most of them have been of a breech forward design, which to me is kind of a holdover from rifle design and on a PCC only serves to lengthen and unbalance what a PCC could be naturally.

I'm talking about the difference between for example the Ruger PC and Breretta CX4. Pistol calibers and magazines are kept short enough by design to fit within a pistol grip that will be comfortable to hold. Rifles have longer cartridges requiring a separate placement of the magazine. So when designing a pistol carbine from scratch, why not go with the magazine in the grip? Which is faster/more ergonomic to reload or would training pretty much make them equal?

The CX4 has a longer length of pull despite being almost 5 inches shorter and a pound lighter. I have to say I much prefer the shorter design for a number of reasons, but then I like bullpups too. Thoughts?

The Tavor is a great example too. I think magazine position is a big part of it as well. While overall length and LOP are important, vertical length is as well, not to mention handling dynamics and positioning for things like reloads.

If you look at the very popular brands in the defense community, lots of different setups. I think it comes down to training and preference. Look at a company like B&T who makes almost all of the form factors.

Hi Point is your friend.

So is Kel-Tec, and Mech Tech and Roni if you count those. I had a 995 with the ATI stock like that, but not FDE. Solid firearm but only 10rds.

All other things being equal, I think most of us consider significantly overall shorter length with no reduction in barrel length or LOP a big positive, so to me it's logically more desirable unless there is some other advantage the breech in front of the trigger guard design brings to the table that I'm unaware of. It seems like reloads would be more natural with the mag in the grip because you're bringing your support hand directly to your strong hand, rather than some point in space out in front. Just speculating.

There is also the Uzi Carbine, works better when you SBR it however. The Model A's came with a faux barrel.

The Model B's did as well. Always wondered the purpose honestly.

Display barrel to look like a real UZI.
