    I gave this product 3 out of 5 stars because I don’t know it well enough yet, I installed it very easily and tested it out right away with standard cheap ball ammo. The very first magazine I had a jam, failure to feed, after that I had absolutely no issues for the next 40 or so rounds, after I put a couple hundred rounds through it I will be more trusting but until then it gets a 3

    The product tended to cause misfeeds when fired with live rounds, the spring is longer and wider than the plate and caused hard binding inside the magazine. Including one time it bound up so bad the top spring got deformed thus ending any further attempts until I can find a propper fitting top spring.

    The P3AT kit works just as well as the CW380 kit I purchased a year ago. Will be looking for the CM9 kits in the future.

    I received the product in due time. However, I had to fiddle with it for over an hour to make the spring work to where the bottom plate would lock. Then another issue came up where after loading the 7th bullet, I can’t lock the mag in place due to the spring clearance. I had to open in up and work the spring.

    USPS failed (like they tend to do) and randomly decided to return my package to sender (yes, they actually did this for no reason, and LIED about it. mag guts uses to print shipping labels, i received the email confirming shipment to the correct address, the address i entered during checkout. the people at my local post office LIED and said the package does not have a full address).

    In spite of this, mag guts, even seeing the package tracking showing this return, have decided to wait until they received this return to mail out a new one. So far it is unclear when they will be shipping, surely it is “someday”, it’s up to a post office which already failed once during this exchange. My first purchase was pleasant, and it inspired a 2nd, this one. Sure, it’s only $20 but this is a nightmare. As a seller on ebay amazon for a decade, would I do the same? Possibly, even probably, and this is generally the feedback I get when doing so. Sorry guys. Don’t think I haven’t given the useless managers at my local post office an ear full too.

    First set didn’t fit my older pistol, however Steve was very helpful & the second set was just perfect. Many thanks for his help in sorting it out. This is my third set & have been very pleased with them.

    The tini KelTec P3AT only holds 6+1. Now, with your “Guts,” it holds 7+1 & it still hangs well, with 8 rounds, in my shirt pocket. Thanks!
