FTF with New 1911 & New 10 Round Mags

[Groundhog92614]

Greetings All:

I am new to 1911s and have a new Dan Wesson PointMan 7 with new Chip McCormmick 10 Round Mags.

In short, a Newbe...Anyway, I had a FTF problem on my first trip to the range, and would like your comment(s). I picked-up the DW & 10 rnd mags for participation at the WEGC Pistol Matches, and need to dial every little thing in right, before competing.

More to the point, I discovered for 1 of the 4 mags (mostly), the gun would not cycle completely from round no. 1 of 10 to round 2 of 10 (mostly). . I was shooting FMJRN. The problem didn't occur with 8 round mags or with the following rounds. The bass went 6 to 10 feet upon ejection.

My question to you'all is What should I do to resolve the problem?, i.e.:

1. Magazine tuning (where to learn/how to do);
2. Break-in period needed (with such a fine gun - really?);
3. Limp-arm (not a chance, as it happened with Rnd 1 only);
4. Common problem with 10 Rnd Mags, so load them only with 9 Rnds.

Your comments, suggestions and insights are all appeciated.

Magazine tuning? Not with new mags. If they work, great. If not, call the maker.

Did you try any of them with, say, 8-9 rounds? I'm thinking "no", because of your last question. Try it. But if I were you, I'd only be using 7-8 round mags anyway. BTW- since it's a new gun, why not just shoot it for a while with the standard mags, so you can minimize your variables? Just my opinion, of course!

10 round mags can be fickle. I like 8 round tripp mags.

ChuckB asks: Did you try any of them with, say, 8-9 rounds?

Yep, and yes the problem went away.

Also, you suggest there is nothing to be done to a new mag (ie deburring)?

If you are starting with a round in the chamber like a tactical load and there is no extra play in the mag spring it puts too much pressure on the slide and prevents it from cycling properly. If you are loading from an open slide then you should not have a FTF if that is the cause. AR 15 shooters load a couple rounds less than capacity to prevent this.

I've been shooting Chip 10rd mags for 3 yrs now without any trouble. My full size(S&W), commander (S&W) and micro compact (Springer) all function very well with the 10rd mags. If it is primarily one mag, load 9rds and see if it still has trouble. If it does then it could the mag, send it back for a replacement. I usually clean them and lube them with gun oil and cleaning patch. It could be slide speed as well, but since the 8rd mags are working fine, I doubt that's the case. Make the offending mag to make sure it is the same one. Is the round being jammed into the feed ramp or is it getting part way into the chamber?
