XD45 vs Glock 21: Chamber Support

Nathan · January 25, 2015, 10:02 AM

I really don't have a bone in this battle. I had a Glock 21 and liked it. Never had chamber support issues that I know of.

BUT, in this thread, this post asked me to compare the 2.

Done. You guys battle it out.

XD45 is the one on top.

I have no trouble using brass from either one to reload. Reliability is the same. To me they are the same, even though the picture shows a big difference.

45 is a low pressure round. It's somewhat of a moot point for that caliber.

But someone asked him if he would post pics and he did.

The only problem I see is that aluminum cased ammo may prove problematic in unsupported chambers for the same reason aluminum cased ammo is unsafe in blowback operated weapons.

Exposed case web + high pressure =

That's was I, thank you. I'm weighing different options in a polymer double stack 45 pistol. Spending several hours a week in the woods above 9000 feet We encounter various critters from time to time. I'd like to have 12 to 15 rounds of 45 super loaded up. (Been using a .357 686) Those pic's are very helpful. The Xd looks pretty good. I just pulled the bbl from the FNX-45, after dropping a round in the chamber I'd say it has about the same case head support as the XD. (Maybe even a hair more). DPM Offers their 3 spring recoil reducer for the XD & the FNX. I don't have pic's, but the FNX 45 has far better chamber support than the FNP 45. Holds 15 rounds, I might have to Try it.
