Help me decide which 5.56 for sd

I look at them from time to time. This particular one even gives you moa drop. I like to look at them to see how many 2 moa red dots I would have to put over someone's head to score a chest hit at 150 yards with a PCC.

PCC, as in 9mm? I don't know specifically but I would imagine the drop of 9mm at 150 yards is quite substantial. At that distance a rifle caliber would be much better. Or maybe 5.7x28? 150 yards is in the envelope of that caliber. CMMG now offers their Guard and Banshee PCC/pistols in 5.7. I'm not entirely sure why but I find the combo compelling.

Yep. 9mm. At 150 yards it's 8.2 inches low and still going at about 1001 fps with 115 gr+p+ Penetrators. I would only need a rifle if going past that distance which I know I'll never need to take a shot past that for self defense.

The PCC would be my bug out gun to go along with my Glock's ammo and magazines. I have hit 12 inch paper targets at 125 yards with it with no problem. I'm sure I can hit 150 but haven't found a range that has that distance. I'm not talking 1 inch groups here but it'll hit a man sized target.

I prefer the PCC over a rifle to get up and go. I don't plan on storming beaches. I just want something that I can shoot accurately to defend myself past pistol distances and keep everything lightweight and uniform.

Plus, I can realistically carry more 9mm than I could .223 on foot and be more mobile. It'll still kill unarmored men and penetrate car doors and auto glass with no problems with more than sufficient penetration.

If I have rifle size and weight I want rifle power to go with it. An AR15 is as light and handy as any PCC and 5.56 will fuck somebody's shit up. Badly. At short range the 5.56 suffers no real disadvantage other than blast, with the right ammo will punch through tougher cover and is just more effective for anything a carbine sized arm could be called upon for. I can carry an ample enough amount of 5.56 on my person. 90 rounds with only two mag belt, 120 if I am using my Magpul drum, or clipped mags. That is plenty. If I needed more I could easily carry 60 more rounds on something low profile such as:

INVRT Bandoleer (AR15, Full Kit)

Or 90 more rounds on a still compact micro chest rig/played carrier setup.
180 rounds is a full combat load, more than enough. Way more. And at a tolerable weight.

Pod, I think at a certain point we overthink things. I'm not saying that a 9mm is better than a .223. It's not. But it kills. It kills in pistol form and from a carbine, it behaves like a .357 Magnum. For years it was the weapon of choice for entry teams throughout the world. It was also used in WW2 with great results. It killed then and it'll kill now. It'll still penetrate auto glass and car doors too. Even more so with the extra velocity it picks up through the longer barrel.

I can carry 3 times the extra amount of ammo as a .223 or the same amount with a much lower weight and utilize the same magazines as my pistol that are on my battle belt. That to me is a positive that outweighs the negatives of range over 100 yards and body armor penetration.

It's a personal defensive weapon. Offensive operations aren't in my cards anymore.
