Here's a old site by Bob Marvel -"Functioning Factors" for the Marvel 1911 - .22 Conversion Units.

The way I adjusted my steel mags was to duplicate the one that worked the best but I remember the dimensions were in line with the above article.

If you are having feeding problemsI fixed mine by releaving the notch where the back of the round comes out of the mag. The old ace conversions had this releaf.

I was having trouble getting my Marvel to function after I first got it. After a double alibi one night a shooter who had a Marvel in his box as a back-up showed me how his magazines had been altered to release the round about 1/8th of an inch sooner. He advised I do the same. I resisted because once done this can't be undone. To keep this short once I resolved my other issues I had no further troubles and I have never touched my mags except to clean them.

I have used the Metalform 22 magazines and have not experienced any issue. With the recent price increases by metalform I found tha I could also use the Ciever mags.

Hi

I did that and it worked so far. You also have to keep them clean.

I have never tinkered with the Metalform mags using my Marvel conversion unit and have never expereincced any problems.

A few years ago Metalform put out magazines with terrible formed lips, especially the fronts. Mags I purchased from Marvel Precision and other retail were bad. I chose to deal direct with Metalform and got replacements that were a little better. However to get 100% function I had to reshape the entire lips to duplicate the original Colt Ace magazines. It took a bit of body and fender work.

The Metalform magazines I recently purchased wouldn't function. I bent the feed lips. I used needle nose pliers and bent the forward parts of the rear and front feed lips to approximate the "spread" as in the article. So, far, so good.
