PDW??

[Stickman]

My PD is part of a rather large multi jurisdictional SWAT team. They selected the Springfield Armory Saint as their primary AR platform. These have 7.5 inch barrels with a blast can (?) On the barrel. They're absolutely obnoxious. This is a photo I took on an indoor range with one of them. Ammo was Winchester Q3131 55 grain. I would much prefer something with three or four more inches of barrel and a BRT Covert Comp on the end.

Teams which are using 7.5" barreled 5.56 weapons have not done their homework and research. It is sinful to allow it, and I would hope that Springfield tried to sway them to another package.

No personal experience but I've seen GD 55gr and I believe Hornady 55gr OTM do well in gel tests from 7.5in barrels.

Please post those results. Real world experiences have shown the 7.5" barrels to be a novelty with no use for departments or others doing Gods work.

Wasn't me. It was a video I found when searching for results. Youtube vid of a guy shooting a 7.5 into gel blocks. If I can find it again I'll post it

I know what you are talking about. Poboyspecial's gel test is questionable at best. Other guys like Buffmanrange also shot GDSPs out of 7.5" barrels and could not replicate the velocities.

Yes that might have been it. Sounds familiar.

I would likewise urge the OP to consider a true PDW or 300 BO. The only thing I regret about my CZ Scorpion is not having 5 times more ammo for it than I actually do.

Holy ****. I am so sorry. So many good options and this is what they got? How did they even arrive there? It is not like Springfield has a large LE presence otherwise.

And this is coming from someone who is not dogmatic enough to say that a 7.5in 5.56 has no serious use anywhere. However as a primary rifle of an entry team it is an absolute non starter.

As far as a PDW. I am a big believer is .300 blackout for the role. There are a couple good options. The Sig Rattler is probably the best if size is the absolute biggest consideration. The Noveske PDW might be worth a look. The Q HB has an adjustable gas block so I don’t recommend it for anything outside of being a toy and Instagram model. I have no experience with the Maxim PDX or the DD PDW.

You need to define the mission.

Mission;

short compact vehicle gun, that I might have to pull out if I drive into something bad.

Mission;

short compact shoulder fired weapon that I can fit into a small backpack that will not scream rifle bag for covert carry

Two different missions, which need different tools to solve.

Yes, OP still has to define what he thinks a PDW is. I assume that he’s not equipping a tank or aircraft crew, so what are we talking about here?

Whoever picked that 7.5” for that agency should find another job. Irresponsible.

I have played around with a few things so I will share my experience toying around.

Anything under 10.5" in 5.56 really isn't worth it. Especially if you wind up throwing a flash can on it because you end up at 10.5 anyway. You are also handicapping your ballistics by going shorter.

I will agree that if you want to go that short in a rifle cartridge 300 is the way to go. After trying this out, it still wasn't worth it to me. Mine was a 8.3". It was still very obnoxious unsupressed. Having to keep different ammo around was not worth shaving 2" of size off.

If you want to go 9mm I think you need to figure out if you are going to suppress it. If no suppressor I suggest going around 8". You squeeze a little more juice out of the 9mm that way. It also gives you more room for your support hand and room to mount anything. I found that when running a suppressor on this size gun though some rounds that might otherwise be subsonic might get going just fast enough to go super and crack. Plus the gun starts to get pretty long again. So when running a 9mm suppressed I prefer to be in the 4-5" range. This is a nice small package but does very little extra that a rds equipped pistol doesn't do.

I honestly kind of gave up on the whole idea though because I am honestly not going to be carrying a shoulder fired weapon around with me. And if for some reason I have too I guess my 10.5 with law folder will have to do.
