I'm curious if anyone here has tried the +1 Magguts solution for adding additional capacity to a factory mag. And if so, what was your experience with it. Thanks.

I use them in my 42 mags with a pearce plus one and haven’t had any problems. I have read that some had had issues but I never have.

I have one kit for my 43. I use Ghost +2 extensions for the spare mags. The Magguts performed as promised. 7+1 capacity with the factory floor plate. I have about 100 rounds through that one mag without failure. I've had it for about a year now and it has been loaded the entire time.

Placing my order now. Many thanks for your responses.

I run magguts on my G43. ~ 500 rds no issues.
