Take a nail or really thin screwdriver (I use a jeweler's driver), push it through the magazine's sight hole just above the cup. That holds the major portion of the coiled spring in place leaving only a couple of the flat spring rungs extended through the bottom of the magazine. They are now easily pushed down into the magazine, the base plate slips right on, remove the jeweler's screwdriver/nail. Done. Total time 30 seconds.
Unrelated to this procedure, I replaced that hideous stubby Kahr +1 bottom plate in the Kahr 9-7 magazine with the Lakeland plate. I also installed a Magguts spring and follower so that mag is now 8+1. It looks good and feels great in hand. I consider the PM9 set up this way a decent carry gun with total of 9 rounds. I added a Hogue Sig P365 grip sleeve, it fits perfectly, feels great in-hand.
(My PM9 is my first Kahr and number #45 in my collection. I jumped on it when I stumbled across it one of my LGS's at $319, ($348 out the door). She is such a sweet shooter that I recently added the CW45 (#46) but won't take possession of it for at least 10 more days. My PM9 is a Massachusetts compliant gun with external slide safety and loaded chamber indicator. I measured the trigger spring tension at 5 lbs so it appears some time in its history the spring was replaced. It is my understanding that MA compliant guns must have a 10 lb trigger so I assume that spring was replaced with a 5 lb spring.)
