So I have decided to get some HST, and I have a couple of questions about it. I am considering the 124 +p, 147, and 147 +p (which I had never seen 147 +p before). This will be used currently in a Glock G17, as well as a Ruger SR9c in the very near future. 147g is supposed to be sub-sonic, correct? If so, does this mean that it makes less noise, and would possibly be better for interior situations where you might be forced to fire your weapon without hearing protection, or will any discharge indoors be so loud as to make this issue pointless? Would there possibly be any recoil differences in these loads? Will one of these rounds be less "snappy" than the others? From what I have seen in ballistics tests on these rounds, they will all penetrate and mushroom well enough for me, so if one of these loads will be easier to control and get back on target faster, that would probably push me in that direction. Thanks in advance for any help, it is greatly appreciated. Also, let me state before someone feels the urge to do one of the old "shoot what your gun eats reliably and you can shoot accurately" responses, if my gun won't eat it and I can't hit with it, I won't continue to use it, no matter what its reputation. I am looking for technical answers, please Wanna kill these ads? We can help!
