There has been much debate about the 45acp use in handguns.   With the number of shootings I have seen where 9mm bullets were used, I’d have to say that the 9mm is definitely not a powerful round, but I have heard of bad guys taking multiple hits from an M4 that kept on coming, so there are many things that can come into play.   The 1911 has remained a popular gun and not because it is the most reliable weapon in 45acp.   I have come to the conclusion that the modern polymer guns are superior to metal guns as far as durability and reliability, but many of them do have crappy triggers.

When the Springfield XD first came out, it was a big deal for 1911 guys to find something that wasn’t a DA/SA handgun and didn’t have a sponge trigger like Glocks do.  You can get a lot of improvement in reliability with a 1911 with good gun magazines like Wilson Combat or Chip McCormick.  I have respect for Glocks, but they do have an odd feel to them and are not traditional.  The XD 45acp felt more natural to a 1911 enthusiast and brought them into the modern world.   The 1911 still has one of the best triggers, but it is not in the same category as some of the guns being made in 45acp these days.   I have several Sig 220 that have been extremely reliable, but Glock has an edge over them as far as endurace.
