It looks the same to me. I thought the 10mm versions were shipping with the red spring? The blue spring is for the XCal I think. I made my own spring out of a CZ-75 spring that has worked flawlessly since install.

Yeah, that might work.  I would have trim it a little where it's proud of the backstrap, but the shelf upfront looks like something I could make work.

I have the other version with a small shelf coming.  If it doesn't look like it will work, I'll order the extended thumb safety and try with that.

Mine shipped with a red spring and when I contacted Grand Power.eu that's what they told me it used. It's what i replaced my worn with. What about you PCFlorida?

Yeah, the decocker lever is totally different. I can see where it would be a pain. It looks like GP has done some redesigning since I got mine. The spring is really confusing.

It took  EAA about 15 years to get Tanfoglio to produce a reliable standard model 10mm.

I'll wait about that long before I grab one of these. They obviously have some bugs to work out.

Your choice, but except for some initial break in and necessary ordinary maintenance mine has been great. In fact, I have had less issues with my GP than my EAA Polymer Compact Carry. I get the feeling that many are allowing a distributors short comings color their opinions of a fine company and their products.

Are you guys saying the recoil spring in the P40 10mm should be a red spring? Mine is a silver colored flat wire spring that is pretty strong. It makes reassembly very difficult. In fact I have been trying for 10 minutes to get it back together and have not been successful. I have some experience with Grand Powers as I have a K100 and an X-Calibur. Both are much easier to put back together. I haven't called Eagle about my problems yet. I was going to do one more range trip tomorrow to see what happens.

Mine is red, but I don't know that they made any changes in the spring. I have found via SavageOne that the best way to put it together is "I have found that if you run the barrel all the way out and reassemble with the barrel hanging towards the floor, it's a lot easier."


And it is :)

After I wrote that post I went back and tried again. I'm not sure what I did different but it went back together on the 2nd try. It will go to the range tomorrow along with a S&W 4013 converted to 10mm. I just got it back from the guy
who did the work for me yesterday.

Remember when you go to reassemble and have compressed the recoil spring to push the tabs down as well. This maybe a little tricky, but if you can also try to use the slide to bump them down. The main point being that the slide won't go back on if the tab is not at least partially down.

When I got my GP I contacted them in Slovakia, they told me the P40 10mm used the red recoil spring and that it was 6.5kg when compressed. That converts to a little over 14#.

They may have changed springs, you would have to contact them for the answer. I am still using the red springs that I ordered from Eagle.

My spring is silver and noticeably longer than the red spring.  It makes reassembly a PITA.  The spring did take a set after the first range visit and it was slightly easier to put the slide back on.  I just hope this gun runs well when dirty because I'm going to avoid field stripping it.

On a positive note, I think that spring softens the recoil impulse by spreading out the force over time.

I got a reply back from eagleimports regarding a question I sent them before I found the safety levers on their site; they said the non-decocker lever (plastic control  for $4) would NOT fit on the P40 decocker model.  I rephrased the question and asked for clarification; they replied with "no, it will not fit".

Based on the pictures though, I think they are wrong.  We'll see when the levers I ordered get here.

Ok, I took my P40 to the range again yesterday. Earlier in this thread someone suggested giving the mag a good hard slap to make sure it fully seats. I tried this but the mag drops persist. Of course the feeding problems continued.
I called Eagle this morning and they gave me the phone number of the place to send it to. Apparently they have different "warranty repair centers" around the country. For me this turned out to be Colorado Gun Works which
interestingly is in Indiana. I am in Kentucky. I have to pay shipping there but they pay return shipping. I wonder how long it will take them to get it back to me?
