10rd magazines for 1911s?
This is something I’ve only delved into once and it wasn’t a great experience. Back in the early 1990’s we had all of that assault weapons ban BS and and aftermarket gun magazines were everywhere. Some of us that owned certain firearms ended up with unreliable firearms that should have been durable. $90 Glock magazines were not uncommon and $14.99 for a jamming Mini 14 30rd magazine from USA magazines, which I believe is been long out of existence. Many people fell back on revolvers and there was a big upsurge back into the 1911 because it was one of those guns that was originally designed for fewer than 10rds which was what the Assault Weapons Ban limited you to.
So some of us messed around with aftermarket 10rd magazines and all of the ones I tried failed pretty quick. We tried to make the 1911 into it’s highest capacity that we legally could, but the balance pretty much got messed up. Gun magazines, even a few rounds bigger than standard capacity can make the gun imbalanced or make it harder holster. There are a lot of reasons to use 10rd magazines like Wilson Combat magazines or Chip McCormick which have a good reputation in competition shooting, but they will protrude considerable. This may cause snagging on shirts ect if you are considering using one for CCW. If you’ve ever practiced with you’re gun, which you should have, firing 8rds and reloading is probable a better CCW than thinking a 10rd magazine is going to give you more protection.
