Thank you everyone for your great comments and welcoming me to the forum! I am sure they will be fine, I just kept seeing articles and reviewers saying, "toss out your stock mags, they are nothing but trouble." There is almost too much information on the internet these days, and not enough good information. So many keyboard warriors out there that have one bad experience with a certain mag or pistol and they bash the company or product.
I'm glad to hear most of you have had good luck with the stock mags. My main concern was feeding and adversely effecting the frame with the metal followers but it sounds like it should be okay. For now I will run the stock mags and update the results, can't wait to take her on the Maiden Voyage!
Any other opinions or comments are still very welcome, thanks!
I'm not sure what the concern is about steel followers in Colt mags.
Normally the follower never touches any part of the gun except the slide stop, which is steel.
I've always used genuine Colt mags by preference and since the 60's I think I've only had one that had a problem and it was a used on that came in a used pistol.
Fact is, pick any brand of magazine and you'll find people who've had problems with them in a gun.
Unless and until a Colt mag gives you a problem, don't worry about it. They really are a top of the line mag. True, they don't have all sorts of extra bells and whistles, but they WORK reliably, which is what it's all about.
Too many people just assume that you must immediately start replacing parts on a new gun to "improve it".
Some of this is a desire to make the gun "theirs" by customizing it, and some is an assumption that a high end maker like Colt is going to supply the gun with a cheesy magazine just because it's cheaper.
Since a really critical part of an automatic IS the magazine it would be really stupid to sell it with a magazine likely to cause problems and a dissatisfied customer and a gun returned to the factory.
Colt magazines are deceptively simply, but they were designed by John M. Browning and have been totally proven in combat and civilian use since 1912.
So, if they work and don't cause problems don't "fix" what ain't broke.
Why spend money on something different when the Colt mags will probably work 100%.
Kind of hard to improve on 100% reliability.
