How Gassy Are PSA AR9mm Pistols?

[jthrelf]

Can anyone comment on how gassy the blowback PSA AR9 pistols are? How about reliability? Concerned about gas because I'm a lefty as well.

I like this configuration:

But also just wondering if the new Ruger PC carbine will be a more shootable, reliable platform. Cheaper too, especially with another $70 in sights for the PSA added. Of course it's pistol vs. rifle and there are pros and cons to both when it comes to PA law (ROS registry vs loaded in vehicle).

A 10" barrel is more handy than 16" and still gives 9mm more punch than standard handguns, but of course the Ruger takes down which is handy as well.

How about muzzle blast in 9mm for 10" vs 16" barrel if an indoor HD shot is taken?
