Feedback on Mag Guts?

I have two for G42 mags and they work very well. I tried them for LCP2 mags and they made it so that way more force was needed to insert the loaded mag into the gun than I was comfortable with, so I returned them.

They are a popular addition to the PPS M2 (ironically not the M1 much to my annoyance). For the PPS M2 they are +1 additions and I haven't seen any problems reported on other forums about them.

I am using a S&W Bodyguard .380 with the Mag guts spring and follower kit and have had no issues at all, It gives me one more round,Yes it takes just a bit more pressure to seat the mag, but function has been perfect. The side even locks open most of the time, as opposed to never when I had the original guts in them.

I bought Mag guts for my CW380 not for the extra capacity, but for the metal follower that they come with. Both my Nano and Pico have some of the best mags I have come across and they have metal followers and I have never had a problem.
The magguts are nice quality.
