I"m looking at getting a suppressor in the near future in a handgun caliber. I know I"m getting a 22lr suppressor but the next step is a centerfire suppressor. Now for my dilemma- which caliber to choose?
I'm currently more of a 40 S&W fan and have a glock 22 and taurus PT101. have no plans to suppress the PT but definitly want to suppress the G22. Most of the ammo I shoot is handloads, so therein lies the problem. I know that pretty much all commercial 147grain 9mm is subsonic by nature. So I can just buy or reload 147 grain loads and be good to go for ammo. if I go the 9mm route, I will buy a conversion barrel for the G22 that's threaded and be set. Well, and i'd have to buy different magazines. Another advantage of having the 9mm would be to buy a 9mm upper for my AR and I can use it on that as well. easy and cheap to shoot. I have dies to reload 9mm but don't currently have any 9mm pistols (well, I do have an old Luger but that's not going to see any use any time soon). I have plenty of 9mm brass around as well. would probably end up with a G17/19 at some point to have a dedicated suppressed setup.
That being said, after reading some of the reloading manuals, it looks like with the 40 S&W if I just load up some heavier bullets (165-180 grain) with the right load of powder it's easy to keep the fps subsonic. advantage is I can keep my G22 stock with a threaded barrel, and maybe get a threaded barrel for my PM40. I have lots of 40 brass and bullets. disadvantage is I haven't seen a 40 AR upper yet.
but not a big deal i'll end up with a suppressor for the AR further down the road (5.56 and 6.
So any thoughts on which caliber works best suppressed? I had been all set to go the 9mm route because of the easy availability of subsonic ammo and other reasons stated above, but thinking about what round I like better and the ballistics when handloaded, I'm considering the 40 again.
either way will probably go with a ti-rant in 9mm or 40 if that matters. if the 9mm works better (i.e. quieter and bigger range of subsonic ammo) I'll go that route. 90% of my shooting is with handloads if that matters.
