This simply the best replacement spring/follower assembly money can buy. Highly recommended.

Great product with fast delivery
Broke a couple of the kits in over the weekend. Great product with fast delivery. I highly recommend this kit. Been a fan of McCormick products for years. Wish they still made the replacement rear sight for 1911s.

The best!
Have been using CM mags for years. Have several kits installed in mags that came with different 1911s. Have followers on backorder, hope they keep making them? Hopefully WC keeps all of the products the same.

I have used these kits extensively in several brands of magazines, they function as advertised with no problems! I will be buying more.

I installed the Magazine Conversion Kit in several magazines without any problem. They are used in action shooting matches monthly and have not experienced any feeding problems. When needed I will buy more of the same. The magazines are used in a MILSPEC 1911.
