Experience with a new Chip Brown Mag

Experience with a new Chip Brown...I mean, McCormick...Mag

Erm..., I mean, "McCormick" (see posts that follow for the ensuing hilarity before I saw what I had done!)

Recently got a couple of 1911's. Decided to get a 10-round mag to use with them, and Chip McCormick's were available (couldn't find a retailer with a WC 10-rounder...told they were coming out with a new version, or something like that).

Here's the Reader's Digest version:

Rock Island Rock Ultra - ran 100 rounds alternating the OEM mag with the Chip McCormick, all fmj. Had a few issues due to thumb-riding the slide (grip change, trying to get hands high as possible...), but all the issues were with the OEM mag, none with the CM, which I thought was very interesting. Once I paid attention to keeping my fingers off the slide, no problem with OEM, but again, alternating mags beginning to end, the issues I had with the OEM I did not have with the CM.

So on the Rock, the CM mag seemed to overcome my own thumb-induced issues.

S&W 1911SC - ran 120 rounds of Hornady Critical Defense 185gr FTX, alternating the Chip McCormick and the OEM. Issues with OEM, none with CM. With the OEM, there were a few times when I would load a mag, using little to no 'force,' the first round would hop out of the magazine and get part way into the chamber! There were a few jams - first round would fire, and the 2nd would nose dive into the feed ramp. I know 1911's have a finicky relationship with SD ammo, but interesting that there were no problems with the CM mag. I also fired about 15 rounds of Federal 230gr JHP's through the OEM no problem, but that's way too small a sample size to judge.

So on the S&W, the CM mag overcame the ammo that wouldn't work with the OEM.

So, good on Chip McCormick! Mags definitely lived up to reputation!

Even with the CM working well, think I'll still look for an alternate SD round. I thought the Hornady might do well because of it's nose shape, but ya never know. Might also add an 8-round Wilson Combat mag to the mix.
