Apologies for the lengthy post, but I want to include a recap of my 10mm saga:
1. I bought an M&P 10mm. I had consistent uncommanded magazine drops with two different M&P 10mm pistols. This was not an uncommon problem with the early M&P 10mm pistols, and I documented it as well as I could (link below). I'm not sure if this problem has been fixed or not with recently manufactured 10mm M&Ps.
2. I then bought a Sig XTen. I've had no issues with the XTen. However, I'm a little wary of the 320 platform. I know that's a hotly debated matter these days, and I'm not taking a position on it. Suffice to say, the mere fact that there's even a debate to be had doesn't leave me feeling great.
3. I bought a Glock 20, thinking this was the no-nonsense way to get a reliable 10mm platform, even though I don't like Glock ergonomics. I was prepared to change the recoil spring assembly to accommodate heavy loads.
Frustratingly, the Glock 20 has been extremely unreliable with 200 grain hard cast and 200 grain hollow points, regardless of recoil spring assembly. At this point I've tried:
-Stock
-Jager products 22#
-Jager products 20#
-DPM RSA, all four different springs with small cap (still need to test them with large cap)
That's a total of 7 different recoil spring assemblies, none of which allowed for reliable cycling of exactly the sort of ammo one buys a 10mm pistol to shoot. Failures to feed as frequently as every or every-other shot.
I've read that extra-power magazine springs might help; I have some on order now. I also have another four configurations of the DPM RSA assembly to try. And I have a KKM barrel on order. Hopefully some combination of these additional parts gets me to a functional pistol.
All this to say: I'm extremely disappointed that the Glock 20 Gen 5 fails to do what a 10mm pistol needs to be able to do, even after trying a bunch of different aftermarket parts to get it to work (none of which should be necessary anyway). I wanted to get another report out there, since it sounds like a lot of other people are having similar problems, but it is still not widely acknowledged that the Glock 20 Gen 5 can't fulfill the purpose for which people generally buy 10mm pistols: defense against four-legged threats, using heavy/hot loads.
