sportsmans has critical duty 135g +P, and critical defense 100g. Their 115g are backordered. What are some of the differences performance wise?
critical defense-barely adequate penetration at best, light loads with low recoil
critical duty-FBI spec penetration and barrier performance, moderate recoil.
For most any competent shooter the critical duty would be the better load, it outperforms critical defense in every test, and usually by a significant margin. The bullet has a thick jacket with a thick cannelure crimp to lock in the hard lead alloy core. Critical defense could help with some tiny BUGs, and for some shooters that have a tough time with recoil, the core alloy is softer, the jacket is thinner, easier damaged through barriers, made primarily for expansion. In some calibers there are more than one load of each, 9mm has 2 duty and 2 defense.
I've tried 3 of the 4 loads(not the 100gr defense), found them to have incrementally more recoil, but still more than manageable from my little Kahr PM9. I carry the 135gr (non +p) duty load, ran about 950FPS in my short 3" barrel and was supremely accurate, +p load ran about 1000FPS, but had significantly more blast and recoil, you have to shoot it side by side with the 115gr to notice the difference in recoil compared to the lighter load, and while the 135gr loads were very accurate, the 115 didn't group as well for me.
The gel tests they have tell the story fairly well, more weight increases penetration, more velocity increases expansion/decreases penetration. These are all the heavy clothing block pics in the links below

Now I shockingly have acquired Glock's in .40 and .357 sig, not sure what round I will use yet.

LMAO "not disapproved"The 125 gr gold dot that is in that box I gave ya
You're " NOT DISAPPROVED" btw
Your feedback is always appreciated. You have great insight into all things for and about Glock.I love the 180gr HSTs in 40, carry them in my G27, can usually find them in 50rd LEO boxes for a good price, probably the best performance in gel of ANY brand, and recoil is relatively light, especially compared to hot 165gr loads. Used to carry the 147gr HSTs in my PM9 till the LE boxed ammo dried up, switched to Critical duty instead of the much more expensive 20rd civvie boxed HSTs. For a fast caliber, I'd probably trust XTPs or the similar Critical duty bullets more, they tend to hold up better than most. I'm not a fan of bonded bullets, the process limits the lead core and jacket to a relatively narrow alloy makeup, uniform thickness(can't control expansion with a thicker jacket base), they tend to underexpand or overexpand outside of a small velocity window, and often shear petals.

What are people's thoughts on the American Gunner line as compared to Critical Duty, in particular for 380? I've read that the XTP will not expand as much as other/newer bullet designs, which for the lower power cartridge seems like a plus to me.
