Neato about that Springfield Armory Omega with its slide having been produced in Germany. I did not know that. Does it digest any and all 10mm ammunition?
The reason I ask is that I've run the Delta Elite through the wringer during the year since I got it back in February of 2016. Sampled all manner of factory loads in it, testing them over the chronograph so I'd have a basis for handloading for the cartridge. Really like the notion of 10mm handgun ballistics.
The Delta Elite has never stuttered with any brand and style of ammunition fed it, but one particular load appeared to be a bit much for the pistol. This was the Buffalo Bore 220 grain lead load.

Seems that the feed ramp, which necessarily intrudes into the chamber, results in inadequate chamber support for the cartridge in this pistol at this load's pressure level. No other heavy factory loads tried, both Buffalo Bore's or Underwood's, exhibited this condition on the fired cases.
The 220 grain cast lead truncated cone bullet clocked 1161 fps out of the Delta Elite's 5-inch barrel. A similar 220 grain cast lead load produced by Underwood produced a roughly similar velocity of 1128 fps with no hint of incipient case head failure.
The factory .45 1911 barrel possesses this same unsupported feed ramp design that leaves a bit of the cartridge case head "hanging out into space" so to speak, however the .45 ACP cartridge operates at much lower pressure than does the 10mm. A really hot .45 ACP handload will occasionally exhibit a bit of expansion, but not the deep "smileys" that is seen here with the 10mm. I thought it was Glock .40 models that were most adept at making "smilies" on their cartridge case heads.
Anyway, during a chronograph session, shooting of this load was halted upon seeing this condition exhibited. The photos don't do justice to the appearance of the cases. They appear extreme, as if one could fail at any moment if the load continued to be used. The pistol has been fine since with all other ammunition used in it. It just gets "indigestion" with this one load.
That is a big ol' Glock Wryfox and your wife is something!
A single Glock 17 lives here, but mostly so I can hate on it. I'm just not a fan of double-action-only triggers of any variation on the design and I think I am allergic to polymer as a firearms parts component. I feel about them in the same way I feel about quartz watches. I could argue for their suitability but don't enjoy owning or using one. They're great ... for someone else.
This photo was taken in Altmunster, Austria. A kind Austrian friend gave me the Glock sign and some Glock factory gimmes to bring back home. He's got connections in Glock and goes to their factory. He also has a vast collection of the "blue steel and walnut" good stuff.
