Looks like I am back in the Super game, with the newer Glock. With the 24 pound ISMI spring on the steel ISMI captured recoil assembly for the Gen3 and the Gen 4 adapter ring, was able to test some today.

The barrel is a lone wolf threaded, so it mics out at 5.98 inches. My 230 XTP recipe was yielding 1250 fps, and the 255 Rim Rock .452 swc was doing just short of 1150 fps. Does not look like the frame abutment face at the front of the front frame rails was taking any real abuse. Not a lot of rounds, but so far so good.

As a point of reference, these loads fired from a fitted Kart 1911 barrel and no comp are way too hot for my 1911. They work fine in a Clark 45 acp barrel with comp, on the same gun. The comped Clark 1911 and my Glock 41 feel about the same at firing and recoil. A good hard thump, easy to get back on target. In the non-comped Kart 1911, nothing close to manageable recoil, and pretty violent.

And my Trijicon RMR held on for the ride, just fine. I am actually kinda impressed, so far. I might throttle back a touch, as this was a bit faster than I was expecting, or probably need.

Of course they are too hot without a comp, 45 Super speeds are 1100 FPS with a 230 jacketed bullet. 460 Rowland top speed is 1300 FPS for a 230 jacketed. You are in Rowland territory

JWP,

Yes, these should be in the 30K psi range. Low end Rowland. But, I have an almost 6 inch barrel, and my plinking loads also chronyed were showing about 50 fps faster than my factory Glock barrel. So I am probably picking up a little speed without the attendant pressure. I was really surprised at how well the Glock performed, without a comp. Recoil was fine, not out-running the magazine or other feed issues.

I will most certainly be treading lightly here, being new to Glocks. With the 24 pound ISMI spring on the conversion Gen3 assembly, 45acp ball (230 at 850) was actually ejecting fine. I am used to that combination just dribbling out of the 1911 modded platform. That's a big red flag, for me. As a matter of fact, I am leaving the 24 in for acp loads, as this was giving much more consistent brass ejection than the stock Glock RSA. The stock RSA gives me a lot of brass upward, landing on my head, and occasionally whacking my RMR.

Trying to stay above Colorado's 550fpe/50 yards hunting ammo rule, so when the weather gets better, I will be get serious looking for an accurate load, hopefully somewhere a little south of these. With the numbers crunched on the above loads, I have more than enough wiggle room here :^)

I greatly enjoy my M21 Glock 460 Rowland. I have found the XTP Mag in 240 grain & Speer GoldDot and Nosler 230 HP are great penetrators and give great mushrooms when pushed at 460 speeds. The plain XTP is not built heavy enough.
