Kinda like motorcycle racing days.
Remember the ad that stated so to speak, if you have a ten dollar head, then buy a ten dollar helmet...........
Pretty much applies to magazines also...........
They may work, but then again, they may not..............
Doesn't mean all the more expensive ones are any better either, just to let ya all know.
The bottom line is, if in doubt, buy "ONE OR TWO" TEST them before jumping in and buying a bunch until you know.
Magazines and ammo usually will be found to be the culprit with a high percentage of issues with a 1911.
Take it for what you will.............
Thanks
