Grand Power P40 10mm -- meh.

[SavageOne]

I talked to Eagle Imports, asking about the silver recoil spring weight and if they were aware of the mag drop issues. This was using their "chat" option on their web site. What I was told was, they don't know the weight of the silver recoil spring(in fact when I told them what GP told me was the weight of the rec recoil spring, I was informed that was more info than they had received) and that they were unaware of the mag drop problem with the 10mm. He said that when a pistol is sent to a warranty center, a problem report is generated and sent straight to GP and that they were not informed of issues themselves. Since I am on the GP forum as well, I asked if GP monitored the forum and was aware of the problem. The answer I got was, well your gun quit doing it, so problem solved and we haven't heard about any other guns doing it.

It would seem that there has been a communication drop somewhere. I would suggest anyone who has had this issue contact both Eagle Imports and Grand Power and let them know. If they don't know they can't address it. Here is a link to the GP forum thread I started about it(I hope I am not violating any forum rules by posting to another forum, if I am please remove the link and accept my apologizes).

So I guess we are waiting for someone who still has the problem (mag drop) to do the same measurements and pictures to see if we see a difference?

[Intercooler]

That would be awesome! Since this began I suspected mag issues first with procedure issues second. I never really thought the pistol itself was the issue.

[Intercooler]

Can anyone with a mag drop unit help us out?

[Intercooler]

We have a shot at figuring this out ourselves if someone with a problem pistol can post up pictures/measurements.

For what it's worth,...when I sent mine in for the mag drop issue I only sent one mag. Now neither mag has given me any drop issues just ftf on the last round.

[Intercooler]

Interesting! So the drop problem is gone and just a last round issue now? I wonder if an EAA extra power spring would do the trick?

[Ten2six]

I will give that a try, my suspicions are the mag follower itself but you may be right. I was manually running some dummy rounds through it it appeared to not be kicking the case head end of the round up fast enough. I hope to get to test some more this week.

[Intercooler]

The follower coil could be tweaked upwards slightly.

[Ten2six]

Thanks, I'll try that first.

[PCFlorida]

Does your follower look the same as mine above? (picture). I see that everyone has raised the price of the magazines now. Eagle Imports has them for $46 each.

[Ten2six]

PCFlorida , mine look just like yours. I tweaked the spring as Intercooler suggested and took some 400 grit sandpaper and lightly sanded the front edge of the followers, also very slightly rounded the leading front edges. I went to the range and the first 150 or so rounds were a complete success! Then started trying some different loads. All in all I had maybe three ftf on the last round. This GP is really coming along. I encourage others to hang in there, they are worth it.

   Some of the EAA/Tanfoglio magazines were plagued for years until the K10 magazines replaced them. I'm sure just about everyone thought it was the pistol in that case too!

How full are you loading your magazines, the full 14?

[Ten2six]

At first I was loading them the full 14, later I would vary from 12 to 13.  I couldn't tell you how many were in the ones that ftf later on ....I was having to too much fun and forgot to keep track.
