I went Sunday and some guy at magazine table was a complete jerk. I was looking for COLT 1911 mags with extended base pads because they work better with my extended magazine well. I told guy what I was looking for and he starts handing me regular, flat bottom, 8-round mags. I told him those wont work for me. He then proceeds to tell they will fit just fine, he's been in the business for 56 years and that I'm wasting his time. I told him again that I know the magazines will fit, but its difficult to slap the bottom of a flat mag into a 1911 with a extended mag well and that's why I prefer the mags with extended base pads. He just walked away ...
But I did manage to eat at Fat Guys Burgers in Tulsa! It was awesome!
If you happen to have any expendable mags, you might look into Ed Brown's mag exchange program. For each 1911 magazine and $10 that you send to them, you can select your choice of stainless body magazines. The 848 8 pack mags would be what you are after.
