Beta32,
My 10mm has had no malfunctions with any magazine except the one it came with. That one appears to be defective in some way, but not sure exactly how. I have not had time to compare it to my others. Beyond that magazine the gun has run 100% with around 150 rounds of factory ammo. The trigger was terrible from the factory. My smith fixed that and it now is excellent in SA, half-cock, and pretty good in DA (I just don't like double action). It still resets forcefully but I suspect the power of the round is to blame. I like the gun a lot as it provides me a CCW suitable 15 shot 10mm, at a very low price. There are times I don't want to carry my expensive 1911s that normally serve my CCW role. As for durability testing it will have to wait until I get my press setup for 40/10. I do not plan to shoot it that much as I am skeptical that it will hold up under extensive use with 10mm. I probably will load down to closer to 40 specs for practice. I have other 10mms for extensive shooting. This one serves its purpose as a cheap defensive gun.
I have not owned one of the earlier polymers so have no basis for comparing those. I think the new guns with rail look better in the P-Carry length. The full size to me looked better without it, and I have never been a fan of Tanfoglio compacts in any configuration. I have seen too many people report functioning problems with the short guns in the higher pressure calibers. I don't think CDNN has the new 9mm. They got a bunch of EAAs old stock when EAA was clearing space for the new guns. You can have an FFL buy a P-Carry direct from EAA if you want one. I no longer have any contacts there, so you would need to call them to find out the details. The 9mm should be an 18 shot and would be pretty neat. I do know that the 18 shot 9mm pistols were getting a lot of customer service calls due to feeding issues, but on my 9mm Stock that was easy to fix. My smith did a little feed-ramp and chamber mouth tweaking. The result is an extremely reliable pistol. Tanfoglio also has a new 9mm 18 shot magazine design to help this. 40 may be a tad more reliable in my experience.
