I carry the +P 135 grain 9mm Critical Duty in my Glock 26, 19, and 17 pistols; but in my G43 I carry Corbon’s +P 115 grain DPX solid copper hollowpoints. My reasoning is that the G43 only has a 3.39” barrel - not enough bore to develop serious velocity with a heavier bullet. The Corbon load produces 1250 fps and 399 ft/lbs in a 4” barrel. I haven’t chronographed it in my G43, but I think that 1175-1200 fps and 325-350 ft/lbs is a reasonable expectation for a barrel that is .6” shorter than the test barrel. In the video below, the tester shoots this load from both a G17 and a G26 through denim layers into ballistic gelatin. It performs virtually identically in either gun - penetration being 13” and 12.5” respectively, with both bullets expanding beautifully. In the G26, the bullet expanded to .86”, and in the G17 it was .88” ...... so the ammo performed consistently between the two guns. The G26’s barrel being 3.42”, or only 0.03” longer than a G43 barrel, it is reasonable to assume that the load will perform about the same in the G43 as in the G26.Grundy1133 wrote:one thing that really drew me to hornady critical duty is that they're waterproofed. the primers are coated with waterproof chemicala nd the casing is crimped to the slug so you dont have to worry about old ammo getting wet from sweating and humid temps (gotta love texas weathercmgee67 wrote:I really like the Hornady XTP 124gr + P in full size and the regular 115 in my sub compacts. The xtp performs very well is very accurate and I whole heartled trust it along with a lot of others I know. The reason I shoot the hotter load in the full size is well because of the full size gun. The weight and size of the gun allow me to use a hotter load. I could carry the same load in my sub compacts but the 115 gr are less snappy and allow me quicker follow up shots and helps me to stay more accurate. When asking about SD ammo it is a can of worms. Almost any
modern HP ammo will do the trick. I think people get so worried that they don’t have the magical bullet. Honeslty I pray the only time I ever have to crank off my HP defensive ammo is when I’m rotating the old out to new fresh stuff. Stay safe and carry on, cheers). im not sure if other ammo is waterproof or not but between that and almost all my friends saying to use hornady, i think ill go with the hornady critical duty for my full size M&P 40

I rarely carry a .45 anymore, but when I do, I carry both my XDS45 and my XDM45 Compact 3.8” with Hornady 185 grain Critical Defense, which generates 1000 fps and 411 ft/lbs from a 3” barrel. The XDS’s barrel is 3.3”, so I would expect at least that performance if not a little more from the XDS, and better performance yet from the XDM - especially now that I have added a threaded barrel to the XDM which adds another 1/2” of barrel. In my 5” 1911, I carry 230 grain HST.
