Hi Folks,
Well, the unthinkable happened: after having finally dumped my $1,200 piece of garbage Springfield TRP 1911 and gotten a Gen 4 Glock 21 due to the need for reliability, I actually experienced a jam with my Glock this past weekend. I have had this pistol for about two months, in which time I have put over 1,000 rounds of 230-grain FMJ through it without incident. This most recent weekend, however, I tried it with hollow points for the first time though (my favorite defensive load: 230gr Speer Gold Dot), and in the second magazine (about shot number 14), I experienced a jam.
The stoppage was very reminiscent of the kind that were common on my 1911 (although that antiquated, overpriced hunk of steel would have the same problem on FMJ all the time), in which the round appeared to have a very pronounced upward angle (about 75-80 degrees up from horizontal), and while it first looked like the cartridge base had failed to slide under the extractor, the actual problem seemed to be that the point of the cartridge jammed on the roof of the chamber where it narrows.
The jam only happened once and very early, and was in a very new magazine which I have not really broken in yet. The other three magazines I have for the pistol fed the JHP rounds fine, and after I confirmed that the other mags worked well, I ran the remainder of the 100 rounds through the troublesome new magazine, and experienced no other issues.
I want to find out from y'all Glock experts whether this is a normal part of the break-in process, whether it might have been just due to a new and stiff magazine, or whether my pistol needs work (other than shooting it a bunch more with hollow points to smooth things out).
Thanks in advance for your advice!
