During a practice session with mec gar 15 round BHP mags, one mag developed a problem with the follower jamming about half way up in its travel causing the rounds above to get all crazy and jam the gun. When examining the condition the top two rounds still in the mag were stuck or jammed together and took some effort to release. So my question here is anyone experienced a similar problem? If so, thoughts? I have taken apart the mag, cleaned and demurred the follower (plastic) and made sure no burrs or obstruction in the mad body.
Possible issues I am thinking.
- ammo out of spec allowing 2 rounds to slip too tight and jam, federal cheap 9mm.
- mag body could be out of spec at that point (wider) allowing two rounds to jam more side by side than proper offset. Visual inspection looks good however.
- follower getting stuck in the body, burr or specs of mag body. However the way those rounds were jammed don't think this was the case.
This is a carry gun so obviously I want all to be flawless. And if testing shows continued issues I will replace the mag. Just thought I would post here to see if anyone has similar experience.
Cheers all
Thomas

Tom,
Could you be experiencing a bad mag spring?? With the mag torn down and the follower moves freely up and down the mag body, then my next thought would be mag spring coil bind, or a weak spring. Just a thought.

Jaypee. Thanks much, what I was looking for in info. Moving to AZ from CA a while ago all my other mags were 10 rounders. So I'm new to expanded cap a Mags. What you relate makes a lot of sense and described the problem perfectly. I'll replace them with some 13 rounders for carry. I'll test these with downloading to 13 or so to see if my confidence returns.

PS (I'm a Ventura native who escaped in '96. [/font][/quote] Ha. : ) I spent my whole life in CA until recently. The first time I walked into a Tucson gun store it was "holly sh@t". Now Feinstein and Pelosi are just bad memories. Since my kids and grandkids still live in CA I have to remember to lock em up at the border. Although last trip I forgot to bring 10 round mags that could have been nasty. Sighhhhh |

I have used only 15rd. Mec-Gar mags in my carry HPs for some years now... I have not seen any difference in the performance between the 13 rd and the 15 rd... One question however... were the mags a problem from the start or did they develop problems later on? Obviously, your experience is different...  V/r Chuck |

One question however... were the mags a problem from the start or did they develop problems later on? Obviously, your experience is different... V/r Chuck Chuck, they have been just fine for say 500 rounds or so of shooting. First time this week when doing drills but it happened at least twice, same problem. I typically don't drop them in the dirt during reloading but could have done that as well. I'll keep working with them and see what develops. Oh I should also point out I was doing rapid fire drills. I just love putting 12-15 rounds in a 6 inch pie plate at 15 yrds as fast as I can pull the trigger and align sights. Appreciate your inputs however. Glad to know your not having issues. That gives me a little more confidence. |

That is certainly an interesting data point.... I think the trick here is to find out what is different now from when the mag was new... A case for Sherlock Holmes!  "The Strange Case of The Unreliable Magazine."  I do wish I could figure out the problem... I use a lot of Mec-Gars and don't want problems. Oh, when did you buy the mag? Recently or is it older? Very puzzling... V/r Chuck |

I had an issue with the 15 round magazines by Mecgar. The HP would lock back leaving the last round in the magazine. I cured this by bending the magazine lips inward causing the rounds to lay flatter in the magazine.

It is perplexing to be sure.
I test all magazines I carry, 15 rd or otherwise...
As a sidebar, I also use the the Mec-Gar 15 rd. mag they make for the SIG P228 as well... again never a problem... maybe I should research that as well...
FWIW

Were the problem mags Matte Finish or Polished Nickel ? I thought the nickel finish mags might have less surface friction (drag) upon the follower.
I'm ok with my 15 round mags - so far.

I have two BHPs, a 69C and a 75C Sport. The only time I experience a failure to feed is on the last round of a 15 round Mec-Gars mag. Most recently it happened once in 100 rounds. Yes, rare, but frustrating due to my excellent care and cleaning of my mags. I may try "tuneing" one mag as suggested by the poster above and see if that works for me.
