The question comes down to: is the extra stopping power and reach of a. Good stopping power, better precision, and yet small/light enough for CQB. This is why I went with a carbine like weapon. Its a tough list that requires extensive thought about which trade-offs are worth being made (and which aren't) because unfortunately you can't have it all in one firearm. 223 which allows for more extensive practicing, so on and so forth. 22lr subsonic suppressed for stealth when needed. 223 suppressed subsonic can be as quite as a. The 9mm is better subsonic for power, but. The 9mm carbine does provide better recoil/noise levels generally speaking, but isn't as good for longer distances (though, it can still have enough fps at 100 yards to expand HPs). The 9mm out of a 16" barrel can be close to a 357 magnum out of a pistol, so even though its not nearly as powerful as a. I need a gun that is good in both CQB and longer ranges, that can be effective indoors and outdoors. I need a gun with enough power to stop someone, but not so much power that it is hard to wield (whether that's due to recoil, noise, weight, size, etc). The problem is, what constitutes "effectively"? This is much more than just ft/lbs of stopping power, I also need a gun with exceptional "shootabilty". The underlying drive for getting this firearm is self preservation, so before all other things, I will need a firearm that can do this effectively. 223 when subsonic (oh how things change), but that is a different issue. The 9mm actually has about twice of the ft/lbs. 223 gets most of its power from sheer speed). Now, the dynamic does a 180 when talking about suppressed subsonic ammo (as the. 223, if sound is the same the hands-down choice would be the. What gives? Granted a suppressed 9mm carbine is closer 125 db with super sonic ammo, you would think that, between a 9mm pistol and. 223 is a little less than 140 db and a suppressed 9mm pistol is also a little less than 140 db (when shooting super sonic ammo). After doing some research, I discovered that (unless I am missing something here), a suppressed. 223, as it has roughly 250% the ft/lbs of a suppressed 9mm when looking at supersonic ammo.ĭecisions, decisions. 223 suppressed, for both super and sub sonic ammo.įor stopping power, you would think the obvious choice would be a suppressed. One factor was my ability to shot this firearm indoors without deafening myself and/or causing hearing damage (I do not plan on doing this on a regular basis, of course!) The other is stopping power.įor sound concerns, you would think the obvious choice would be a suppressed 9mm carbine, as anecdotal testimony suggests it would be significantly quieter than a. Though this decision making process is too long to really address right now, I have be weighing two factors heavily in my mind. Has anyone tried running subs and supers through the same rifle without modifications and got reliable cycling?I have been considering getting either a. This would be a major draw for me if they did cycle and it would help me overlook the hefty prices for this ammo and pistol. Has anyone tried subsonics in the pistol and had them cycle reliably? Even being a blowback it is still designed to manage and cycle based on full power rounds and could have problems with a suppressor and lower powered rounds producing less force to overcome the springs? I do like the idea of having 50 rounds in the PS90 where the first 10 or so are subs then 40 supers to follow it up or having 3 or 4 subs in a pistol with 17 full power ones waiting to go. Even a 240gr 300BLK moving the same speed is hit or miss getting through soft armor and it has over 4 times the energy. 22LR size and power so any vest that can be defeated by a. I would seriously doubt any 55gr bullet going 1,000fps would get through soft armor. Has anyone tried running subs and supers through the same rifle without modifications and got reliable cycling? View QuoteInteresting take on the 5.7 and PS90.
