Guns and shooting advice?

[Diamondback]

I usually shoot Shotokan myself, either "pure" or modified for second pistol. (Which means on recoil the fired side pulls back and the other moves into Shotokan firing position and discharges, then the transition cycle repeats the other way. Buys the just-fired side a little more time for trigger reset and recoil recovery... but it seems to work better for me than for my shooting buddies at the range, so don't bet your life on something that seems to be a tailor-made compensator for my maladapted physiology.)
