I've had 3 G20s and a couple of G29. Currently have 1 G20 3rd gen and 1 G29 gen 4. Never had an issue running them. My gen 3 G20 has about 2k plus rounds thru it. Kkm barrel, phantom adj trigger, dpm system, polished internals. Underwood, DT, Silver tips, hot loaded home brew recipes. Same results with the G29 with same upgrades.

Tried posting pic but image was too large. will try to crop it down today. The catcher looks and works amazing. Perfect angle, nice pocket area for brass to stay in and it can be assembled and disassembled in seconds. All fits in a nice bag
Will start working on gen 2 in a couple of weeks.

I have the dpm system on my G20 3rd gen works great. I was going buy another for g29. But looks like it sticks out and was built for a different gun. Wondering who has either for g29 and how they like it. Tungsten gsa or dpm system.
Thanks

I made 1 using spare parts at home I will add pics and plans cost me $4.58 to build. Works great

CFE Pistol Powder test 10mm 135 grain HST over 10.2 grains CFE Pistol seated to 1.2500"
CCI 350 primer Star*-*Line Brass (used but pass-through reconditioned)
Velocity 1672 fps from the Glock 20 factory barrel, Wolff non captive recoil rod & 22lb spring.  Max case expansion is 0.4325"

I'll have to test more for consistency, but I was impressed with this loading performance, pressures were easy on the brass, powder burned cleanly. 

Any more results from testing. I don't have a chrony or any other form of measuring speed but 180gr gold dot over 8gr of cfe powder seated to 1.25 feels very stout and the round is very accurate. No signs of over pressure on brass or primer. For my needs think I'm good there. Worked up slow from 6.7 gr. Kkm stock length barrel and 22lb triple spring Dpms setup. Glock 20 3rd gen
