Military Arms Channel (MAC) has reviewed the Grand Power P1.
The review is here:
I find it interesting that he’s experiencing the same issues that I have with my P11 — failures to return to battery. He was pretty put-off by that, which is understandable. What’s weird is that some people experience the issue while others do not. I know the gun does not like being extremely dirty (it doesn’t take a lot of rounds before it’s deemed dirty, either). The gun also likes to be wet with lube, which probably isn’t going to help with carbon…it makes for a pasty mix.
He’s also the first major reviewer I’ve ever seen that has experienced such issues. Or maybe he’s the first that’s bold enough to report about it. In the past, I’ve stated that I find it weird that no reviewers have ever had negative comments about this gun. That’s the main reason I did so many videos of the gun…because I felt people were possibly hiding negative experiences of the Grand Power handgun platforms.
One thing that MAC should do is not use CLP. That’s what I was initially using and it is not enough, as it moves around and will eventually evaporate. Apparently grease is a no-go as well, as Dave Copping joined in offering guidance to MAC in that video’s comments section (Dave Copping works for Eagle Imports). He needs a heavy oil — heavy oil will migrate less. I used oil (synthetic motor oil) the last time I took the P11 to the range…I still had FRTBs, although I shot 150 rounds of Wolf, which probably counteracted the motor oil. As a reminder, Wolf generates a LOT of carbon.
It seems that the only way around the FRTBs would be to do a field strip of the weapon at the range to wipe it down enough to lessen the FRTBs so that the range session could continue. Or use a clean-burning ammo (depending on the ammo, that could be expensive).
MAC also wants to apply the MAC reliability test to his P1 (it consists of dunking the gun in water, sand, and mud, firing a mag in between each medium). That gun is going to fail that test. It’s not that type of gun. It’s a very tight gun, tolerance-wise…such guns are not typically reliable when it comes to being subjected to such tests. I left a comment stating that the gun will probably fail the test. I’m not sure if he’s going to submit it to the test anyways, but I seriously doubt it’ll pass.
