.45acp Magazines

I realize Pictures I posted are 4516 7 rd mags because I have more examples readily available with better pictures. The 4506 mags I have are similar.

As I understood the feed problems began with the 4506/4516. I am not aware of problems with 645/745 or other earlier 45 pistols most of which had the earlier metal base pre-4506/4516 mags.

And I realize some have had no problem with various mags in their pistols. I would not hesitate to use at the range - but…..

Maybe this was covered above, but I was unable to glean from earlier post. Currently only the black followers are available for sale . Can a black follower be used reliably in either a yellow or orange follower mag? Has anyone changed the older mags to black follower? In a 4506 mag? In a 4516 mag? Would it be beneficial to "upgrade" to the black?

Thanks,

Rosewood

Yes for sure. Years ago when rebuilding my original 4506-1 magazines I replaced the yellow followers with black. There was no other choice that I found then. Now I see NOS yellow followers are available but they are more expensive than the black.

The black followers are flawless in the “must have yellow follower” marked magazines. The benefit of the black ones are the availability plus whatever upgraded design change.

I think I read somewhere that it’s ok to replace old style followers with current - orange or yellow with black followers in the 4506/4516; yellow with blue in 40xx; yellow with white in 10xx. Only contrary was orange and yellow in 45’s not interchangeable.
 
The color change in the follower denotes design changes in the mag body and floorplate. It's a quick reference color code.

Replacing your orange and yellow followers to black changes nothing. It's not an upgrade.
 
The issue with the yellow follower magazines was the shape of the lips. I don't think changing followers solves the problem.
 
I picked these up a few years ago, black follower revised mags. Still have them in the packaging. Hell I have had the gun for 35 years and have yet to fire it.
