I am planning to build an AR pistol to play around with. I have built two AR's and am currently building a third, so I am not new to the AR world.

I have read these posts about the pistol not always cycling properly and that part of this is caused by the short duration of gas pressure. I am also an AK nut - and it seems that the Krinkov is not subject to this problem near as bad. Now I know this is like comparing apples to oranges, but hear me out. The Krinkov has a special flash suppressor that also acts as a muzzle booster much like the browning 1919 and M2. It helps retain enough gas pressure long enough to let the action cycle properly.

Now, is there any reason why we couldn't come up with something similiar to use with the AR and hopefully allieviate much of these problems. Input is greatly appreciated!

Use a suppressor. Or just buy an entry stock buffer and  have a carbine gas system, that helps too.

I know the carbine buffer/tube works better, but that just defeats the purpose of the pistol. I know it may seem trivial, but that just destroys the "look" of the pistol.

I plan on purchasing a few suppressors in various calibers in the near future, but a weapon should be able to cycle without one.

Maybe go with a longer barrel?

Well, yeah that would help, but again - that would defeat the purpose of a very compact pistol variant. As soon as I get another lower and a 7.5 pistol kit, I will machine something up and test it out. Guess I need to get a Krink muzzle device to take apart and see what makes it tick..........

Wasn't there a thread around where people bought wolff 1911 springs and fixed the problem?
