Are Glock chambers cut to the large end of SAAMI specs? If so (as I read but now can't find that article) is it fair to compare a tight chambered 1911 to a Glock? Has anyone compared a mil-spec 1911 .45 to the Glock 22? Given current sights I believe the 1911 is as accurate and reliable as any plastic-fantastic. I shoot an old 1911 with a military barrel. My buddy has a new Colt with a Kart match barrel. Mine will feed and chamber anything, his balks at most reloads unless a factory crimp (LEE) die is used. It has balked at some el-cheapo factory ammo as well. His is more accurate when it runs. When fed a load it likes it will shoot groups at 25 yds. half the size of my old gun.

Glocks are designed with very loose tolerances in mind for utter reliability in feeding. Hence the 1911's edge in accuracy in most cases. Most complaints are from the "unsupported 6 oclock" which is in fact what allows them to feed twisted abused brass from the magazine :> This may be a factor in choosing a .40 and 180gr rounds as the 180 gr rounds have VERY little room for error as the bullet is back as far is it can go already, and the loose barrel tolerances may create catstrophoc failure (too high of pressure)kb! if the ALL the wrong conditions are met. This is not as common as people let on. I'm of the mindset that glocks and 1911 are two different animals all together, the only similarity is they throw chunks of metal downrange at slow speeds :> Just my observations over the years...

When I was looking to get a Barsto barrel installed on my Gold Cup, I stumbled upon an article in one of the gun magazines out at the time (Guns & Ammo I believe). The author made mention that Barsto's match barrels come with match dimension chambers and that they would be less forgiving of ammunition variations. He suggested requesting them to ream the chamber to standard Colt dimensions to get the upmost in reliability. I did so but they sent my pistol back with the match chamber. I use the 200 SWC lead load and got a lot of jams. I sent the barrel back and they reamed it out for me and now it shoots great. If you are willing to take the extra care in selecting and assembling your ammo a match barrel is great. I chose to favor more reliability at the cost of some potential loss in accuracy.

You can make a 1911 as accurate as anything a handgun has to offer. But I also know that the Glock is more accurate than most can shoot. I,like many others,have both and I feel as well armed with either. The 1911 will always be King, but the glock has to be just below it.

Glock chambers and reliability aren't a problem. I have owned both Glock, and 1911. I have found the Glock to have excellent reliability. A Glock is a lot more forgiving than many 1911's, and the glock design has better use in certain applications than a 1911, and vice versa, IMO.

The myth about Glocks in .45ACP having excessive unsupported chamber area can easily be debunked by taking the barrel from the .45 Glock and the barrel from your favorite 1911 and comparing them with a round dropped into them. You'll find that most 1911's have as much unsupported web as the Glock 45's. I have three 1911's, and two 45 Glocks, and they all seem to have almost the exact same profile as far as unsupported chamber area.
