Does my Glock 17 chamber give less support to the brass than my Beretta 92 or Sig 226 pistol chamber? The reason for the question is that when resizing my 9mm brass those brass that were fired in my Glock seems to require more force than one from my other 9mm pistols.

BTW. I've heard that Glock's loose chamber is one of the reason why they are such reliable pistols.

That's a good question. Contrary to what you might have heard, the Glock 9mm has a fairly tight chamber compared to say a Beretta 92 or FN/Browning Hi-Power.

Try taking a few fired (empty) 9mm Para cases fired thru a FN/Browning Mk. III Hi-Power and insert them into the chamber of a Glock 9mm and then do the vise-versa. The once-fired Hi-Power cases are a tight fit in a clean Glock 9mm chamber. Once-fired Glock cases fall into and out of a Hi-Power chamber like $&it thru a goose. Same for a Beretta 92. Just one example.

Now if were talking about the Glock pistol in .40S&W, that's a whole other story.....
